Every day, thousands of apps are launched. Over time, the tech industry is speeding up and making smart and big changes rapidly, such as new OS versions, a bunch of new devices, development platforms, frameworks, and much more. Due to all of these, a mobile app tester's job has become much more complex and challenging. In this blog, we are going to share some hacks of mobile app testing that will make app testers' job much easier.
First of all, let's discuss some common challenges of mobile app testing. OS fragmentation, multitude of mobile devices, different mobile app types (Native, Hybrid, HTML5), a variety of testing tools, numerous test interfaces, and performance testing under natural conditions are some common testing challenges for mobile. How do we overcome all these challenges? What do we do if we are stuck on one challenge? Below, we have tried to consolidate all possible information that every mobile app tester should know and follow.
Understand the Nature, Scope, and Goal of the Application
A skilled mobile app tester always makes it their first step to test with a great understanding of the project. A mobile app tester needs to have an in-depth understanding of the project to become aware of its nature, scope, and ultimate goal.
Know Your Customers
According to today's scenario, mobile users expect much more from the mobile apps and mobile devices than from web or desktop, so knowing your target customer's expectation is essential. A mobile app tester can know the app audience by its niche or nature. For example, if the app is in the category of dating, then they can identify the ideal age of the app audience that should be in between 18 to 30. So, on the basis of the age, the tester can sort the devices. The app tester can downsize the testing efforts by focusing on what is important to the app audience related to functionality, UI/UX, like/dislikes, and more.
Testing Strategy and Plan
Formulating a testing strategy helps to wager necessary guidelines which all testers are expected to follow. This brings consistency in testing and ensures sufficient test coverage.
Test on Real Devices
Emulators and simulators are very useful for the early stages of development, but testing on real devices ensures real test results and gives the tester a better idea about the look and feel of the app.
User Experience Testing
User experience testing is the most important task for every tester. 80% of the app's success depends on users, so a mobile app tester should properly test the user journey execution, UI consistency, UI behavior, visual issues, user interaction visualization, custom device feedback, responsive design behavior, and application-specific functionality.
Compose a List of Devices for Testing
Create a list of devices and OS's on which you are going to apply testing strategies. You can also avoid the devices that are no longer supported by manufacturers and vendors. You can use the help of emulators if you want to test on an older version.
Test Native and Web-Based Mobile Apps Differently
Native Mobile App Considerations
When you are testing a native mobile app, the testing cycle should start from the installation and launch process. Access to the device ID is needed, and if the app uses third party API, API connection testing is also required.
Web Based Mobile App Considerations
If the application requires an internet connection, then connection testing is important for Wi-Fi, mobile data, 2G, 3G, 4G, 5G, GPRS, etc. The application's pages will look different while checking it on different browsers, so check things according to visuality. Load and performance testing is one of the major factors to test in web-based mobile applications.
Perform Automation Testing
Mobile app automation can improve the development process. If you are developing app in an agile environment, automation testing can save hours. It is very easy to add new test cases without interfering in the development process with the help of automation testing.
Performance and Connectivity
Check the memory leaks and remove the redundant code; it can lead to higher battery consumption. If the app uses GPS and the camera, make sure it will stop after the application is closed because it can increase the battery issues. For connectivity, application memory, and processor usage, transition behavior when switching between Wi-Fi and 3G/EDGE, weak signal conditions, and network bandwidth usage are necessary functionalities to test.
Security Perspective Testing
Check for encryption and authentication of data, proper encoding of sensitive data, the interaction of the app with third party software or services, and potential areas of the app that can receive malicious information.
Application Global Acceptance Testing
If the application has worldwide appeal, you have to properly check that the app adapts to various geography, support languages, currencies, and popular social networks in prominent markets.
Test for Updates and Install/Uninstall Processes
As we all know, the versions of mobile app platforms change frequently, so testing the app's update and installation processes is an essential task. A mobile app tester should do testing in order to replicate updating from an older application version to the latest one. During the update and installation tests, mobile app testers must take care of crashes and other issues like that. They must also check that after uninstalling the application, the app data has been completely removed from device storage.
Check All Log Files and Restrict Permission
Everybody who uses a smartphone is very sensitive about their private data. Users do not like to install an app that requires unnecessary permissions. For example, if the app requires only a camera and internet connection, there is no reason to get permission for SMS, contact numbers, and that kind of thing. In this test scenario, mobile app testers must connect the mobile device to a computer to check the log files, stack traces, device storage, and that kind of information that is not allowed to be there. They should also check for log cases to make sure the log is in release mode and avoids showing too much app information to other people.
