Developing a QA automation solution that operates independently of a connected PC is a challenging yet rewarding endeavor. This article explores how to run an instrumentation test programmatically from within an Android app, specifically focusing on Appium UiAutomator2 tests.
Understanding the Challenge
The goal is to execute a QA test on an Android device without relying on a connected PC. Typically, such tests are run using the command adb shell am instrument -w. However, executing this command directly from an app encounters permission issues, notably the lack of INTERACT_ACROSS_USERS_FULL permission, leading to a NullPointerException when attempting to access the UiAutomation instance.
Potential Solutions
One approach to tackle this issue involves manipulating the Android operating system’s security features, which are designed to prevent unauthorized actions akin to malware behavior. Here are some potential solutions:
- Build a Custom ROM: By creating a custom build of the Android Open Source Project (AOSP), you can modify the
Manifest.xmlto include the necessary permissions. This involves setting the protection level to “signature” and signing the ROM with the same key as the app. This is a complex process that requires significant effort and resources. - Utilize System Apps: If possible, convert the app into a system app, which inherently has more privileges. This approach, however, is limited to devices where you have control over the system image.
Practical Considerations
For many users, building a custom ROM or modifying system apps is not feasible due to the technical complexities and potential risks involved. Therefore, exploring alternative test automation tools that can operate efficiently without these hurdles is advisable.
Exploring Alternative Solutions with Repeato
If you’re seeking a more straightforward solution for test automation on Android, consider using Repeato.
