  • Google’s CTS-D is a new test module to help developers identify compatibility issues with Android devices.
  • The CTS-D will allow app developers to contribute test cases that others can use.
  • Google hopes that Android OEMs will utilize these tests to help identify issues more effectively.

Google is introducing CTS-D, a new module within the CTS (Compatibility Test Suite). It will be utilized by app developers and is open-sourced within the Android Open Source Project (AOSP). The new module’s goal is to enable more efficient communication among app developers, OEMs, and Google, while also assisting in resolving compatibility issues to make sure apps run consistently across devices.

The CTS is already a crucial part of the company’s Android Compatibility program, where smartphone OEMs run tests on their devices during development to recognize bugs and fix them as early as possible. Android engineers normally write these tests, and the CTS holds a collection of two million test cases to check Android device compatibility.
