Each new feature of the development needs to be tested. Functional testing is an important aspect of mobile app testing, and mobile testers should perform manual and automated tests. At the beginning of the test, the tester must manually test the mobile app as a "black box" to see if the functionality provided is correct and works as designed. In addition to classic software testing, like clicking a button to see what happens, testers must also perform more versatile mobile device-specific testing.
Today, modern mobile devices have touch screens that require multi-touch actions to interact with them. The device can be a portrait or landscape display. They provide motion, tilt and helical sensors. They have different interfaces to connect to other devices or services, such as GPS,NFC, cameras, LEDs, and so on.
The mobile software tester must ensure that all of the app's specific device features are available in the app. There are so many types of mobile devices that it is not possible to test all of the coverage, so the testers have to focus on the key to their app when it comes to functional testing. What is really simple and effective? Device rotation. I found a lot of bugs during my test work that only needed to rotate the device from portrait to landscape and back.
In addition to the entire manual testing process, test automation is also important for mobile apps. Each code change or new feature can affect existing features and their status. Usually the manual regression test time is not enough, so the tester has to find a tool to perform automated regression testing. Now there are many mobile test automation tools in the market, there are commercial and open source, for different platforms, I usually use the AI Beta (http://www.detect.cn) automated testing to detect mobile app security vulnerabilities.
