Initial value:

= {
        
        {std::regex(".*ES3.*"), CtsEnforcement::kNever}}

SkSL error tests are used by CTS to verify that Android's RuntimeShader API fails when certain shader programs are compiled. Unlike unit tests these error tests are defined in resource files not source code. As such, we are unable to mark each test with a CtsEnforcement value. This list of exclusion rules excludes tests based on their file name so that we can have some form of control for which Android version an SkSL error test is expected to run.
