OpenGL ES testing
This page provides an overview of the GPU testing suite called deqp (drawElements Quality Program).
You can access the code for deqp in AOSP at the following location:
To work with the latest submitted code, use the deqp-dev branch. If you want the code that matches the Android 5.0 CTS release, use the lollipop-release branch.
Deploying deqp
To deploy the deqp test suite to a new environment, please review the deqp information regarding the following:
- Building test programs
- Porting the test framework (optional, depending on the target platform)
- Running the tests
- Automating the tests
- Using special test groups
- Integrating with Android CTS
