Currently we don't have any tests written for this project as its really hard and complex to write tests for GLSL shaders and OpenGL-ES programs.
But I think we can write tests at least for Utility functions and other basic APIs.
Resources to learn basics of testing-
JUNIT5 - testing framework for Java and JVM
how to start writing tests for GLSL shaders
Writing tests in Android
Android OpenGL unit testing
What do you think @codeanticode about this ?
