"""Generates necessary files for unit test versions for testing.
After adding/changing RenderScript unit tests, run `python RSUnitTests.py`
to ensure that forward/backward compatibility tests run properly.
This file is so when updating/adding unit tests there is one central location
for managing the list of unit tests and their versions.
This is necessary since forward compatibility unit tests are chosen at compile
time where backward compatibility tests are chosen at runtime.
Generates a Java file for backward compatibility testing.
Generates an Android.mk file for forward compatibility testing.
