A native application is created for use on a platform like mobile and tablets. Hi Nancy, Thanks for sharing the information with us. Can any one send it to me at: Can any one send it to karthik gmail. For example, in a family of 50 repeats where 42 have a T base pair in the same position, the consensus sequence would have a T at this position as well, as the base pair is representative of the family as a whole at that particular position, and is most likely the base pair found in the family’s ancestor at that position. Types of Mobile App Testing:

This approach is independent of screen size and mainly used for Android devices. Image-based mobile testing tools — create automation scripts based on screen coordinates of elements.

In addition to functionality based test cases, Mobile application testing requires special test cases which should cover following scenarios. The scope of the testing depends on a number of requirements to be checked or the extent of changes made to the app.

If the changes are few, a round of sanity testing will do. An example application testing project: ILL International Learn Lab is an application designed to help admin, publisher to create websites in collaboration.

Using a web browser, instructors choose from a set of features to create a class that meets their requirements. Identify the types of testing: We need to do usability, functional and compatibility testing on different browsers with the combinations of manual and automation test cases.

Manual and Automated testing: The methodology followed for this project is Agile with the iteration of two weeks. Every two weeks dev. Automation team creates scripts for the set of basic functionality and runs the scripts that help determine if the new build is stable enough to test.

The Manual testing team will test the new functionality. Once the iteration gets over, iteration planning meeting held where dev. The team, product owner, business analyst, and QA team discuss what went well and what needs to improve.

User Acceptance Testing is done by the client. They re-verify all the bugs to make sure every bug was fixed and the application is working as expected on every approved browser.

Performance testing team tests the performance of the web app using JMeter scripts and with different the loads on the application. The web app gets tested across multiple browsers – both using different simulation tools as well as physically using real mobile devices.

After every 4th week, the testing moves into staging, where a final round of end to end testing on these devices is performed to make sure the product is ready for production.

And then, it goes Live! It is very important for the testers who test their apps on both iOS and Android Platform to know the difference between the both. You might have gone through all the tutorials, I have put in some major differences here, which in turn will help you as part of your testing: For Example, Samsung S2 size is too small when compared with Nexus 6.

There are high possibilities that your app layout and design get distorted on one of the devices. Probability is low in iOS as there are only countable devices available in the market and out of those many phones have similar resolutions.

For Example, before iPhone 6 and above came into existence all the older versions had the similar size only. You can refer to the below diagram to understand the concept of image resolutions: So, it is quite probable that your app may behave slowly on lower-end devices.

Device manufacturers decide when to upgrade their devices. It becomes a very difficult task to test everything both with the new OS and the old OS. Also, it becomes a cumbersome task for the developers to modify their code to support both the versions.

For Example, when Android 6. To clarify further, the user could change permissions location, contacts at app level also. Now the testing team owes the responsibility to make sure that showing permissions screen on the app launch on Android 6.

In Android, if a user is added to beta users list then he can see the updated beta build on the Play Store only if he is signed in into the play store with the same email ID which is added as a beta user.

I have been working in Mobile Testing for the last 2 years on both iOS and Android Platform and all the key points mentioned below in this tutorial are from my personal experience and some got derived from the issues encountered in the project.

Everyone has their own style of testing. Some testers just focus on what they see from their eyes and the rest are passionate about everything that works behind the scenes of any mobile application.

I know things are difficult to understand without citing examples. Testing should not just be limited to exploring the mobile app and logging bugs. We, as a QA should be aware of all the request that we hit our server and the response that we get out of it.

Configure Putty to view logs or verify sumo logic for logs depending on what is being used in your project. It not only helps you in knowing the End-to-End flow of the application but also makes you a better tester as you get more ideas and scenarios now.

Nothing comes into this world without any reason. Any statement should have a valid reason behind it. We could potentially see our app crashing if these kinds of exception keep creeping.

As we have mentioned about App Crash in the last sentence, this leads the QA to have access to crashlytics of the project. Now the question over here is that if the tester has seen app crashing then why does he need to bother about crashlytics?

The answer to this is quite interesting. There are some crashes which may not be visible on the UI but they are logged on crashlytics. It could be out of memory crash or some fatal exceptions which may impact the performance later.

Citing a simple Example, say you are working on a chat application like WhatsApp which supports sending images and videos and the application is built on both iOS and Android platforms Development may or may not be going in sync.

Another important advice for mobile testers — Please keep checking the size of your app after each release. For mobile testers, app upgrade testing is very important. Data retention is also equally important as in whatever preferences the user has saved in the previous version should be retained when he upgrades the app.

For Example, a user might have saved his bank card details in apps like PayTm, etc. Yeah, many devices may not support your app. Many of you must be knowing that vendors write their own wrappers on the top of US and it could be possible that any SQL query of your app is not compatible with the device and hence it throws an exception and it may result in not even launching the app on that phone.

Point over here is — Do try to use your app on your own devices except for the ones you use in the office. It is quite possible that you see some issues with your app. Next on the list is Permission Testing of mobile apps.

I have seen few testers who make a mistake by not testing the proper combinations of these permissions. I can recall a real-time Example when we were testing a chat app which had all the features of sharing images and Audio files.

Permission for Storage was set to NO. Now, when a user would click on the Camera option it never opened till the permission for storage is set to YES. The scenario was ignored as Android Marshmallow had this functionality that if storage permission is set to NO, the camera cannot be used for that app.

The scope extends further than what we have discussed in the above paragraph. We should make sure that the app is not asking for any permissions which are not used. Any end user familiar with the software industry may not download the app in which too many permissions are asked.

If you have removed any feature from your app, then make sure to remove the permission screen for the same. Comparing with the other similar apps on the same platform can strengthen your argument that the functionality under test will work or not.

Lastly, a majority of you have might have come across situations where your builds got rejected by Apple. As a tester, it becomes difficult for us to cater the technical aspects but still, there is some rejection criterion which the testers can take care of.

For more information on this, please click here. Try to engage yourself in activities which take place well before the code comes to your bucket to test. Also, be ready to share your views if you require modifications.

This applies to all the testers who are working on various domains and platforms. I am sharing this because I have seen the app crashing after launching it, say after around 14 hours from background state.

The reason could be anything depending on how the developers have coded it. Let me share a real-time Example: In my case token expiration was the cause behind it. For one of the chat apps if launched after hours would be stuck on the connecting banner and would never get connected until killed and relaunched.

These kind of things are very difficult to catch and in a way, it makes mobile testing more challenging and creative. In the mobile world, the performance of your app impacts the extent to which your application is getting recognized worldwide.

As a testing team, it becomes too important to check your app response and more importantly how it works when a large number of users are using it all together. If we consider what is going on behind the scenes, then it is a request which is going on to the server with the PayTm UserID and the server sends back the response with the balance in your account.

The above case is only when one user has hit the server. We need to make sure that even when users hit the server, they should get back the response well on time because end-user usability is our prime goal.

I would conclude this tutorial by re-iterating that mobile testing seems to be very easy in the beginning but as you keep digging in you will understand that it is not easy to ensure that whatever developed will run smoothly on thousands of devices all over the world.

You would mostly see the apps that are supported on latest and last few versions of OS only. Scenarios like battery consumption, interrupt testing, testing on different networks 3G, Wi-Fi, testing while switching networks, monkey testing of mobile apps, etc are all useful when it comes to mobile testing.

The attitude of testers matters a lot when it comes to the real testing environment. Well, this has been our effort to fulfill multiple requests from our readers on a mobile application testing guide.

Thanks to Swapna, Hasnet, and many other mobile testing experts for helping us compile this series! I have recently joined a Mob App testing project, the contents mentioned above are really greatful, thank u so much for sharing.

The information what you are giving is very helpful. Can you please forward information on Health Domain Application also. I would suggest to add for the Types of testing Mobile App internationalization and localization.

Many of the mobile applications have to be translated into several language. It is the nature of these application to be sold wherever in the world. It is very useful for the beginners who want to build career in testing mobile app.

Every thing is explain point to point. Must read post for all the testers. Personally the post has enhanced my knowledge about mobile test. Hi Dear I am working as a desktop software tester and also i want to learn about Mobile Test.

So above this information are really helpful, and appreciate you. Can you please foreword me about test case write for mobile app test and other information. Thanks for your good co-operation.

I would like to know about the kind of defects that are unique and individual needs to focus on while their testing. What are the simple defects founds? What are the critical defects found?

We have updated the article with a spreadsheet for download containing the sample test cases for testing mobile applications. Thanks for sharing the information. How could i use them to test my Hybrid apps?

This information is really helpful to us Thanx for increasing our Knowledge regarding mobile test as well as Testing Mobile application. Simple Defects — If we are rotate our devices in landscape or portrait mode the the page gets distorted.

Critical Defects — pop up handling – some times pop up wont display to user and if it displays the functionality wont work. Thank you very much for sharing this article.

I totaly new in Testing Mobile app. Now this is a good way to start learning about mobile app test with proper explanation. This is informative article for a great start.

I do manual Mobil app testing for iOS and Android for functionality. But i am lot more interested in automation testing and Load and performance testing for a mobile app.

Can you help me with the article for iOS and Android.? And also tell us more about choosing the tool? If you have any information on Automation testing for Mobile using on demand software. While the user is using the app, if a call come or an SMS arrives — how the app behaves at that time.

Also when we end the call or come back to teh app after reading the SMS how the app behaves 4 Text field labels, tool tips wrapping is not done correctly. Text might appear correctly on one device but might not wrap properly on devices with small screen sizes 5 OS differences, the app.

These were my 2 cents, will keep posting more. Mobile Automation Testing Tools that are getting popular in the market are: Choosing the right tools depends on which tools meets your and the clients requirement.

If the budget is tight then one shud go for Cloud otherwise when budget is not a constraint then testing on real devices is advisable. However, one should surely test the app. You can also check the Responsive design is Google Chrome using below steps with multiple devices.

Launch your application 2. Press F12 or Console Drawer 3. Click on Sources tab 4. Go to Emulation tab Check your application in different devices. I am a student who has a great deal of experience and knowledge.

I have a great deal of time and interest in this opportunity to make a career in the testing of a new application, and I will have the ability to do marketing and administration.

I have sent you a email and I would like a little more information, please contact me if you have any suggestions and time. The best thing is this article is bringing a good way of a career to the masses.

Nancy — Wonderful article and gives a clean picture for a individual like me who is just looking for info on the various aspects of mobile Test. I am seeking information on Regression Testing of mobile applications.

Initially when the application is built — it was tested by a Team which is currently not exisiting. Now with the Ios upgrades and the android upgrade – i want to know how should i plan to do Regression Testing for the applications Hybrid.

My Email id is — pk. Can you help me And also tell more about choosing the mobile test automation tool and working. Hi, I am planning to attend interviews on Testing Mobile application.

Can anyone suggest me how to prepare for that? Thank you for your information. If you provide real time videos to test mobile apps it is very help full to people like me to learn mobile test easily.

Thank you for Sharing this post. It would be more helpful for freshers like me if you share some demo videos on mobile test. I want to ask one thing we want to learn how companies are doing mobile test practically, how to set up environment for testing, how test cases will prepare what are the terminologies they used in companies by this we can learn more things theory part we can study..

Very useful guide for beginners. Mobile users are unforgiving when it comes to poorly performing applications. This is a really useful article. It covers all the things needed for a start in mobile test.

I am new to testing mobile, however i need more info about how to write test cases for testing mobile applications. Can you please guide me the tools which can be used for recording and testing Native iOS application.

Can any one suggest me the tool for regression testing in mobile test. Your help is appreciated. I liked this article. I am looking for test plan preparation, test case prep and execution, defect life cycle, automation etc.

Very useful information…while i am exploring some mobile automation tools, came to know one automation tool i. Automation tool mAutomate is available and is available for testing on one device i.

Link for mAutomate http: I was looking for some information on line to under stand how to text Mobil applications manually with the help of emulation settings.

Various viruses and TEs also share features in their genome structures and biochemical abilities, leading to speculation that they share a common ancestor. Because excessive TE activity can damage exons, many organisms have acquired mechanisms to inhibit their activity.

Bacteria may undergo high rates of gene deletion as part of a mechanism to remove TEs and viruses from their genomes, while eukaryotic organisms typically use RNA interference to inhibit TE activity.

Nevertheless, some TEs generate large families often associated with speciation events. Evolution often deactivates DNA transposons, leaving them as introns inactive gene sequences.

It exists in the human genome as an intron and was activated through reconstruction. Large quantities of TEs within genomes may still present evolutionary advantages, however. Interspersed repeats within genomes are created by transposition events accumulating over evolutionary time.

Because interspersed repeats block gene conversion, they protect novel gene sequences from being overwritten by similar gene sequences and thereby facilitate the development of new genes.

TEs may also have been co-opted by the vertebrate immune system as a means of producing antibody diversity. TEs can contain many types of genes, including those conferring antibiotic resistance and ability to transpose to conjugative plasmids.

Some TEs also contain integrons, genetic elements that can capture and express genes from other sources. These contain integrase, which can integrate gene cassettes.

There are over 40 antibiotic resistance genes identified on cassettes, as well as virulence genes. Transposons do not always excise their elements precisely, sometimes removing the adjacent base pairs; this phenomenon is called exon shuffling.

Shuffling two unrelated exons can create a novel gene product or, more likely, an intron. The first TE was discovered in maize Zea mays and is named dissociator Ds. Likewise, the first TE to be molecularly isolated was from a plant snapdragon.

Appropriately, TEs have been an especially useful tool in plant molecular biology. Researchers use them as a means of mutagenesis. In this context, a TE jumps into a gene and produces a mutation.

The presence of such a TE provides a straightforward means of identifying the mutant allele relative to chemical mutagenesis methods. Sometimes the insertion of a TE into a gene can disrupt that gene’s function in a reversible manner, in a process called insertional mutagenesis ; transposase-mediated excision of the DNA transposon restores gene function.

This produces plants in which neighboring cells have different genotypes. This feature allows researchers to distinguish between genes that must be present inside of a cell in order to function cell-autonomous and genes that produce observable effects in cells other than those where the gene is expressed.

TEs are also a widely used tool for mutagenesis of most experimentally tractable organisms. The Sleeping Beauty transposon system has been used extensively as an insertional tag for identifying cancer genes.

De novo repeat identification is an initial scan of sequence data that seeks to find the repetitive regions of the genome, and to classify these repeats. Many computer programs exist to perform de novo repeat identification, all operating under the same general principles.

However, it is important to identify these repeats as they are often found to be transposable elements TEs. De novo identification of transposons involves three steps: There are three groups of algorithms for the first step.

One group is referred to as the k-mer approach, where a k-mer is a sequence of length k. In this approach, the genome is scanned for overrepresented k-mers; that is, k-mers that occur more often than is likely based on probability alone.

The length k is determined by the type of transposon being searched for. The k-mer approach also allows mismatches, the number of which is determined by the analyst. Some k-mer approach programs use the k-mer as a base, and extend both ends of each repeated k-mer until there is no more similarity between them, indicating the ends of the repeats.

As these programs find groups of elements that partially overlap, they are useful for finding highly diverged transposons, or transposons with only a small region copied into other parts of the genome.

These algorithms perform a Fourier transformation on the sequence data, identifying periodicities, regions that are repeated periodically, and are able to use peaks in the resultant spectrum to find candidate repetitive elements.

This method works best for tandem repeats, but can be used for dispersed repeats as well. However, it is a slow process, making it an unlikely choice for genome scale analysis. The second step of de novo repeat identification involves building a consensus of each family of sequences.

A consensus sequence is a sequence that is created based on the repeats that comprise a TE family. A base pair in a consensus is the one that occurred most often in the sequences being compared to make the consensus.

For example, in a family of 50 repeats where 42 have a T base pair in the same position, the consensus sequence would have a T at this position as well, as the base pair is representative of the family as a whole at that particular position, and is most likely the base pair found in the family’s ancestor at that position.

Transposable elements have been recognized as good candidates for stimulating gene adaptation, through their ability to regulate the expression levels of nearby genes.

Although most of the TEs were located on introns, the experiment showed the significant difference on gene expressions between the population in Africa and other parts of the world.

The four TEs that caused the selective sweep were more prevalent in D. However, not all effects of adaptive TEs are beneficial to the population. Down regulation of such genes has caused Drosophila to exhibit extended developmental time and reduced egg to adult viability.

Although this adaptation was observed in high frequency in all non-African populations, it was not fixed in any of them. At the same time, there have been several reports showing the advantageous adaptation caused by TEs.

In the research done with silkworms, “An Adaptive Transposable Element insertion in the Regulatory Region of the EO Gene in the Domesticated Silkworm”, a TE insertion was observed in the cis-regulatory region of the EO gene, which regulates molting hormone 20E, and enhanced expression was recorded.

While populations without the TE insert are often unable to effectively regulate hormone 20E under starvation conditions, those with the insert had a more stable development, which resulted in higher developmental uniformity.

These three experiments all demonstrated different ways in which TE insertions can be advantageous or disadvantageous, through means of regulating the expression level of adjacent genes. The field of adaptive TE research is still under development and more findings can be expected in the future.

TEs are mutagens and their movements are often the causes of genetic disease. They can damage the genome of their host cell in different ways: Diseases often caused by TEs include hemophilia A and B, severe combined immunodeficiency, porphyria, predisposition to cancer, and Duchenne muscular dystrophy.

Additionally, many TEs contain promoters which drive transcription of their own transposase. These promoters can cause aberrant expression of linked genes, causing disease or mutant phenotypes.

One study estimated the rate of transposition of a particular retrotransposon, the Ty1 element in Saccharomyces cerevisiae. Using several assumptions, the rate of successful transposition event per single Ty1 element came out to be about once every few months to once every few years.

Cells defend against the proliferation of TEs in a number of ways. If organisms are mostly composed of TEs, one might assume that disease caused by misplaced TEs is very common, but in most cases TEs are silenced through epigenetic mechanisms like DNA methylation, chromatin remodeling and piRNA, such that little to no phenotypic effects nor movements of TEs occur as in some wild-type plant TEs.

Certain mutated plants have been found to have defects in methylation-related enzymes methyl transferase which cause the transcription of TEs, thus affecting the phenotype. TEs are found in most life forms, and the scientific community is still exploring their evolution and their effect on genome evolution.

It is unclear whether TEs originated in the last universal common ancestor, arose independently multiple times, or arose once and then spread to other kingdoms by horizontal gene transfer.

In this way, they are similar to viruses. Various viruses and TEs also share features in their genome structures and biochemical abilities, leading to speculation that they share a common ancestor.

Because excessive TE activity can damage exons, many organisms have acquired mechanisms to inhibit their activity. Bacteria may undergo high rates of gene deletion as part of a mechanism to remove TEs and viruses from their genomes, while eukaryotic organisms typically use RNA interference to inhibit TE activity.

Nevertheless, some TEs generate large families often associated with speciation events. Evolution often deactivates DNA transposons, leaving them as introns inactive gene sequences.

It exists in the human genome as an intron and was activated through reconstruction. Large quantities of TEs within genomes may still present evolutionary advantages, however. Interspersed repeats within genomes are created by transposition events accumulating over evolutionary time.

Because interspersed repeats block gene conversion, they protect novel gene sequences from being overwritten by similar gene sequences and thereby facilitate the development of new genes.

TEs may also have been co-opted by the vertebrate immune system as a means of producing antibody diversity. TEs can contain many types of genes, including those conferring antibiotic resistance and ability to transpose to conjugative plasmids.

Some TEs also contain integrons, genetic elements that can capture and express genes from other sources. These contain integrase, which can integrate gene cassettes.

There are over 40 antibiotic resistance genes identified on cassettes, as well as virulence genes. Transposons do not always excise their elements precisely, sometimes removing the adjacent base pairs; this phenomenon is called exon shuffling.

Shuffling two unrelated exons can create a novel gene product or, more likely, an intron. The first TE was discovered in maize Zea mays and is named dissociator Ds. Likewise, the first TE to be molecularly isolated was from a plant snapdragon.

Appropriately, TEs have been an especially useful tool in plant molecular biology. Researchers use them as a means of mutagenesis. In this context, a TE jumps into a gene and produces a mutation.

The presence of such a TE provides a straightforward means of identifying the mutant allele relative to chemical mutagenesis methods. Sometimes the insertion of a TE into a gene can disrupt that gene’s function in a reversible manner, in a process called insertional mutagenesis ; transposase-mediated excision of the DNA transposon restores gene function.

This produces plants in which neighboring cells have different genotypes. This feature allows researchers to distinguish between genes that must be present inside of a cell in order to function cell-autonomous and genes that produce observable effects in cells other than those where the gene is expressed.

TEs are also a widely used tool for mutagenesis of most experimentally tractable organisms. The Sleeping Beauty transposon system has been used extensively as an insertional tag for identifying cancer genes.

De novo repeat identification is an initial scan of sequence data that seeks to find the repetitive regions of the genome, and to classify these repeats. Many computer programs exist to perform de novo repeat identification, all operating under the same general principles.

However, it is important to identify these repeats as they are often found to be transposable elements TEs. De novo identification of transposons involves three steps: There are three groups of algorithms for the first step.

One group is referred to as the k-mer approach, where a k-mer is a sequence of length k. In this approach, the genome is scanned for overrepresented k-mers; that is, k-mers that occur more often than is likely based on probability alone.

The length k is determined by the type of transposon being searched for. The k-mer approach also allows mismatches, the number of which is determined by the analyst.

Some k-mer approach programs use the k-mer as a base, and extend both ends of each repeated k-mer until there is no more similarity between them, indicating the ends of the repeats.

As these programs find groups of elements that partially overlap, they are useful for finding highly diverged transposons, or transposons with only a small region copied into other parts of the genome.

These algorithms perform a Fourier transformation on the sequence data, identifying periodicities, regions that are repeated periodically, and are able to use peaks in the resultant spectrum to find candidate repetitive elements.

This method works best for tandem repeats, but can be used for dispersed repeats as well. However, it is a slow process, making it an unlikely choice for genome scale analysis. The second step of de novo repeat identification involves building a consensus of each family of sequences.

A consensus sequence is a sequence that is created based on the repeats that comprise a TE family. A base pair in a consensus is the one that occurred most often in the sequences being compared to make the consensus.

For example, in a family of 50 repeats where 42 have a T base pair in the same position, the consensus sequence would have a T at this position as well, as the base pair is representative of the family as a whole at that particular position, and is most likely the base pair found in the family’s ancestor at that position.

Transposable elements have been recognized as good candidates for stimulating gene adaptation, through their ability to regulate the expression levels of nearby genes.

The applications that work on mobile devices and their functionality are tested. Even in the mobile applications, there are few basic differences that are important to understanding:. A native application is created for use on a platform like mobile and tablets.

Testing applications on mobile devices is more challenging than testing web apps on the desktop due to. As with any application, Mobile application testing is also very important, as the clientele is usually in millions for a certain product — and a product with bugs is never appreciated.

It often results in monetary losses, legal issue, and irreparable brand image damage. To address all the above technical aspects, the following types of testing are performed on Mobile applications.

The Test strategy should make sure that all the quality and performance guidelines are met. A few pointers in this area:. This decision mostly relies on the clients.

The client or the app builders consider the popularity factor of certain devices as well as the marketing needs for the application to decide what handsets to use for testing. The emulator is a system that runs software from one environment to another environment without changing the software itself.

It duplicates the features and works on the real system. MobiReady — With this, not only can we test the web app, we can also check the code. Responsivepx — It checks the responses of the web pages, appearances, and functionality of the websites.

Screenfly — It is a customizable tool and used to test websites under different categories. Cloud computing is basically running devices on multiple systems or networks via the Internet where applications can be tested, updated and managed.

For testing purposes, it creates the web-based mobile environment on a simulator to access the mobile app. Object-based mobile testing tools — automation by mapping elements on the device screen into objects.

This approach is independent of screen size and mainly used for Android devices. Image-based mobile testing tools — create automation scripts based on screen coordinates of elements.

In addition to functionality based test cases, Mobile application testing requires special test cases which should cover following scenarios. The scope of the testing depends on a number of requirements to be checked or the extent of changes made to the app.

If the changes are few, a round of sanity testing will do. An example application testing project: ILL International Learn Lab is an application designed to help admin, publisher to create websites in collaboration.

Using a web browser, instructors choose from a set of features to create a class that meets their requirements. Identify the types of testing: We need to do usability, functional and compatibility testing on different browsers with the combinations of manual and automation test cases.

Manual and Automated testing: The methodology followed for this project is Agile with the iteration of two weeks. Every two weeks dev. Automation team creates scripts for the set of basic functionality and runs the scripts that help determine if the new build is stable enough to test.

The Manual testing team will test the new functionality. Once the iteration gets over, iteration planning meeting held where dev. The team, product owner, business analyst, and QA team discuss what went well and what needs to improve.

User Acceptance Testing is done by the client. They re-verify all the bugs to make sure every bug was fixed and the application is working as expected on every approved browser.

Performance testing team tests the performance of the web app using JMeter scripts and with different the loads on the application. The web app gets tested across multiple browsers – both using different simulation tools as well as physically using real mobile devices.

After every 4th week, the testing moves into staging, where a final round of end to end testing on these devices is performed to make sure the product is ready for production.

And then, it goes Live! It is very important for the testers who test their apps on both iOS and Android Platform to know the difference between the both. You might have gone through all the tutorials, I have put in some major differences here, which in turn will help you as part of your testing: For Example, Samsung S2 size is too small when compared with Nexus 6.

There are high possibilities that your app layout and design get distorted on one of the devices. Probability is low in iOS as there are only countable devices available in the market and out of those many phones have similar resolutions.

For Example, before iPhone 6 and above came into existence all the older versions had the similar size only. You can refer to the below diagram to understand the concept of image resolutions: So, it is quite probable that your app may behave slowly on lower-end devices.

Device manufacturers decide when to upgrade their devices. It becomes a very difficult task to test everything both with the new OS and the old OS. Also, it becomes a cumbersome task for the developers to modify their code to support both the versions.

For Example, when Android 6. To clarify further, the user could change permissions location, contacts at app level also. Now the testing team owes the responsibility to make sure that showing permissions screen on the app launch on Android 6.

In Android, if a user is added to beta users list then he can see the updated beta build on the Play Store only if he is signed in into the play store with the same email ID which is added as a beta user.

I have been working in Mobile Testing for the last 2 years on both iOS and Android Platform and all the key points mentioned below in this tutorial are from my personal experience and some got derived from the issues encountered in the project.

Everyone has their own style of testing. Some testers just focus on what they see from their eyes and the rest are passionate about everything that works behind the scenes of any mobile application.

I know things are difficult to understand without citing examples. Testing should not just be limited to exploring the mobile app and logging bugs. We, as a QA should be aware of all the request that we hit our server and the response that we get out of it.

Configure Putty to view logs or verify sumo logic for logs depending on what is being used in your project. It not only helps you in knowing the End-to-End flow of the application but also makes you a better tester as you get more ideas and scenarios now.

Nothing comes into this world without any reason. Any statement should have a valid reason behind it. We could potentially see our app crashing if these kinds of exception keep creeping. As we have mentioned about App Crash in the last sentence, this leads the QA to have access to crashlytics of the project.

Now the question over here is that if the tester has seen app crashing then why does he need to bother about crashlytics? The answer to this is quite interesting.

There are some crashes which may not be visible on the UI but they are logged on crashlytics. It could be out of memory crash or some fatal exceptions which may impact the performance later.

Citing a simple Example, say you are working on a chat application like WhatsApp which supports sending images and videos and the application is built on both iOS and Android platforms Development may or may not be going in sync.

Another important advice for mobile testers — Please keep checking the size of your app after each release. For mobile testers, app upgrade testing is very important.

Data retention is also equally important as in whatever preferences the user has saved in the previous version should be retained when he upgrades the app. For Example, a user might have saved his bank card details in apps like PayTm, etc.

Yeah, many devices may not support your app. Many of you must be knowing that vendors write their own wrappers on the top of US and it could be possible that any SQL query of your app is not compatible with the device and hence it throws an exception and it may result in not even launching the app on that phone.

Point over here is — Do try to use your app on your own devices except for the ones you use in the office. It is quite possible that you see some issues with your app. Next on the list is Permission Testing of mobile apps.

I have seen few testers who make a mistake by not testing the proper combinations of these permissions. I can recall a real-time Example when we were testing a chat app which had all the features of sharing images and Audio files.

Permission for Storage was set to NO. Now, when a user would click on the Camera option it never opened till the permission for storage is set to YES. The scenario was ignored as Android Marshmallow had this functionality that if storage permission is set to NO, the camera cannot be used for that app.

The scope extends further than what we have discussed in the above paragraph. We should make sure that the app is not asking for any permissions which are not used.

Any end user familiar with the software industry may not download the app in which too many permissions are asked. If you have removed any feature from your app, then make sure to remove the permission screen for the same.

Comparing with the other similar apps on the same platform can strengthen your argument that the functionality under test will work or not. Lastly, a majority of you have might have come across situations where your builds got rejected by Apple.

As a tester, it becomes difficult for us to cater the technical aspects but still, there is some rejection criterion which the testers can take care of. For more information on this, please click here.

Try to engage yourself in activities which take place well before the code comes to your bucket to test. Also, be ready to share your views if you require modifications.

This applies to all the testers who are working on various domains and platforms. I am sharing this because I have seen the app crashing after launching it, say after around 14 hours from background state.

The reason could be anything depending on how the developers have coded it. Let me share a real-time Example: In my case token expiration was the cause behind it. For one of the chat apps if launched after hours would be stuck on the connecting banner and would never get connected until killed and relaunched.

These kind of things are very difficult to catch and in a way, it makes mobile testing more challenging and creative. In the mobile world, the performance of your app impacts the extent to which your application is getting recognized worldwide.

As a testing team, it becomes too important to check your app response and more importantly how it works when a large number of users are using it all together. If we consider what is going on behind the scenes, then it is a request which is going on to the server with the PayTm UserID and the server sends back the response with the balance in your account.

The above case is only when one user has hit the server. We need to make sure that even when users hit the server, they should get back the response well on time because end-user usability is our prime goal.

I would conclude this tutorial by re-iterating that mobile testing seems to be very easy in the beginning but as you keep digging in you will understand that it is not easy to ensure that whatever developed will run smoothly on thousands of devices all over the world.

You would mostly see the apps that are supported on latest and last few versions of OS only. Scenarios like battery consumption, interrupt testing, testing on different networks 3G, Wi-Fi, testing while switching networks, monkey testing of mobile apps, etc are all useful when it comes to mobile testing.

The attitude of testers matters a lot when it comes to the real testing environment. Well, this has been our effort to fulfill multiple requests from our readers on a mobile application testing guide.

Thanks to Swapna, Hasnet, and many other mobile testing experts for helping us compile this series! I have recently joined a Mob App testing project, the contents mentioned above are really greatful, thank u so much for sharing.

Can you help me with the article for iOS and Android.? And also tell us more about choosing the tool? If you have any information on Automation testing for Mobile using on demand software.

While the user is using the app, if a call come or an SMS arrives — how the app behaves at that time. Also when we end the call or come back to teh app after reading the SMS how the app behaves 4 Text field labels, tool tips wrapping is not done correctly.

Text might appear correctly on one device but might not wrap properly on devices with small screen sizes 5 OS differences, the app. These were my 2 cents, will keep posting more. Mobile Automation Testing Tools that are getting popular in the market are: Choosing the right tools depends on which tools meets your and the clients requirement.

If the budget is tight then one shud go for Cloud otherwise when budget is not a constraint then testing on real devices is advisable. However, one should surely test the app.

Nancy — Wonderful article and gives a clean picture for a individual like me who is just looking for info on the various aspects of mobile Test. I am seeking information on Regression Testing of mobile applications.

Initially when the application is built — it was tested by a Team which is currently not exisiting. Now with the Ios upgrades and the android upgrade – i want to know how should i plan to do Regression Testing for the applications Hybrid.

My Email id is — pk. Can you help me And also tell more about choosing the mobile test automation tool and working. Hi, I am planning to attend interviews on Testing Mobile application.

Can anyone suggest me how to prepare for that? Her work was largely dismissed and ignored until the late s—s when, after TEs were found in bacteria, it was rediscovered.

Transposable elements represent one of several types of mobile genetic elements. Class I TEs are copied in two stages: This copied DNA is then inserted back into the genome at a new position. The reverse transcription step is catalyzed by a reverse transcriptase, which is often encoded by the TE itself.

The characteristics of retrotransposons are similar to retroviruses, such as HIV. Retroviruses can also be considered TEs. These integrated DNAs are termed proviruses. The provirus is a specialized form of eukaryotic retrotransposon, which can produce RNA intermediates that may leave the host cell and infect other cells.

The transposition cycle of retroviruses has similarities to that of prokaryotic TEs, suggesting a distant relationship between the two]. The transpositions are catalyzed by several transposase enzymes.

Some transposases non-specifically bind to any target site in DNA, whereas others bind to specific target sequences. The transposase makes a staggered cut at the target site producing sticky ends, cuts out the DNA transposon and ligates it into the target site.

This results in target site duplication and the insertion sites of DNA transposons may be identified by short direct repeats a staggered cut in the target DNA filled by DNA polymerase followed by inverted repeats which are important for the TE excision by transposase.

Cut-and-paste TEs may be duplicated if their transposition takes place during S phase of the cell cycle, when a donor site has already been replicated but a target site has not yet been replicated.

Not all DNA transposons transpose through the cut-and-paste mechanism. In some cases, a replicative transposition is observed in which a transposon replicates itself to a new target site e.

Activator element Ac is an example of an autonomous TE, and dissociation elements Ds is an example of a non-autonomous TE. Without Ac, Ds is not able to transpose. TEs are mutagens and their movements are often the causes of genetic disease.

They can damage the genome of their host cell in different ways: Diseases often caused by TEs include hemophilia A and B, severe combined immunodeficiency, porphyria, predisposition to cancer, and Duchenne muscular dystrophy.

We, as a QA should be aware of all the request that we hit our server and the response that we get out of it. Although most of the TEs were located on introns, the experiment showed the significant difference on gene expressions between the population in Africa and other parts of the world. Class I TEs or retrotransposons generally function via reverse transcription, while Class II TEs or DNA transposons encode the protein transposase, which they require for insertion and excision, and some of these TEs also encode other proteins.
