- Mobile Application Testing is the gate way to provide a high-quality mobile app
- A quality test is done in various verticals; so, that the mobile app passes before they reach their target mobile devices or app stores, and become available for public.
- It is mainly tested for its functionality, usability, and consistency
- It ensures the app in the mobile devices is user friendly.
- Mobile application testing can be done automatically or manually.
- There are many tools used for automating the mobile application testing, but using the right tool at the right place is the most important
- Nowadays most of the mobile phones are enriched with advanced features and applications to meet the needs of the end user; so, to make it an effective application, various testing process are involved in testing the mobile application

Installation Testing (Whether the user can install the application smoothly or not).
- Basically, Mobile devices use two types of applications:
- Applications that automatically comes with mobile OS (while installing OS, it automatically gets installed),
- Applications that we should install specially from the store to use the application.
![mobile application testing](https://www.mstsolutions.com/wp-content/uploads/2020/12/image-16.jpeg)
- Installation testing involves the process of testing an application’s installation and uninstallation process
- It also includes testing whether the specific application can be updated properly without any interruption
Functional Testing
- Functional testing is the most basic test performed on the functional behavior of the application to ensure that the application is working as per the defined requirements.
![mobile application testing](https://www.mstsolutions.com/wp-content/uploads/2020/12/image-17.jpeg)
Key points for functional testing of the any mobile app:
- Check out that all the functional flow of the application works as per the business logic.
- A thorough testing should be done on the developed application in all major devices and versions for its functionality.
- Make sure the application works properly, even if the memory is full
- Be certain on the security of the data, If the application is integrated with any e-pay/payment gateway.
- Check out whether the proper informative messages are displayed, If the application is forcefully stopped during page loading or navigating
Performance Testing
- Mobile performance involves the client application, server and network performance so it is important to get hold on the performance scenarios in performance testing
![mobile application testing](https://www.mstsolutions.com/wp-content/uploads/2020/12/image-1186.png)
- Performance testing also involves testing other scenarios like low battery power due to heavy battery use, network out of coverage area/poor bandwidth/changing internet connection mode (2G, 3G, or WiFi) /changing broadband connection, transferring heavy file, etc.
- Performance testing is mainly done to make sure that the device doesn’t freeze or crash, if a user performs same operation again and again
Interruption Testing
- Interrupt Testing is used to check how the mobile application performs when an interrupt occurs
![mobile application testing](https://www.mstsolutions.com/wp-content/uploads/2020/12/image-18.jpeg)
Mobile applications should be able to handle different interruptions for example
- Incoming and Outgoing calls, SMS and MMS.
- Low Battery Notification.
- Data Cable Insertion and Removal.
- Network Provider outage and recovery.
- Device Power cycle.
- Network Connection type: Application should easily run on Wi-Fi or 4G or 3G or 2G connections.
- The app should work properly even if there is no SIM card in the device (provided it is independent of Mobile Service Network).
- The app should function as expected in the Aero plane mode
- SD Card Interaction: This factor can play a vital role in the mobile device.
- App should provide an option to move the app to SD card and its functioning should also be proper.
Usability Testing
- The most important factor that should be taken extra care of while developing a mobile application is its usability.
- It should take place from the early stage of application development
- The success and failure of any application depends on its User Interface.
Usability testing considers three main features and evaluates the application based on them
- Efficiency
- Effectiveness
- Satisfaction
![mobile application testing](https://www.mstsolutions.com/wp-content/uploads/2020/12/image-20.jpeg)
- UI of the app should be as per device screen size and no text/control should be cutting off.
- Text should be readable.
- Progress indicator should be provided in case of app/page load. So, that the user is aware that the app is fetching some data.
- Button size should be proper and large enough that it should be easily clickable by the large fingertip, and spacing between 2 buttons should also be good enough.
Memory leakage Testing
- Compared with the computer memory, the mobile devices have very limited memory; so, there is a high possibility for Memory leakage,
- Memory leakage happens when a computer program or application is unable to manage the memory it is allocated and that results in poor performance of the application and the overall slowdown of the system.
- As mobile devices have significant constraints of available memory, memory leakage testing is crucial for the proper functioning of an application
Example:
- Keep the application running for ten minutes and observe if memory usage remains stable.
Security Testing
- The purpose of security testing is to mainly test the application’s data and network security as per the given requirement/guideline.
![mobile application testing](https://www.mstsolutions.com/wp-content/uploads/2020/12/image-19.jpeg)
Example:
- Verify that a session automatically gets expired if it remains inactive for more than 15 minutes.
Operational Testing:
- Operational testing’s main purpose is to make sure that the back-up and recovery process is working as per the requirement
Conclusion:
All the above methodologies involved in Mobile Application Testing are to ensure that the users trust the applications for mobile devices.
Summary:
With the help of these testing types, we make sure that the application is 99.9% tested and applications satisfy the user requirements.
