35Description:
36
37Color clear tests are organized based on the feature set used in the
38test case. Each test case performs multiple iterations, each consisting
39of multiple color clears. Parameters, such as color, scissor rectangle
40or color mask are chosen using deterministic random number generator.
41
42Results are verified by building a reference image and comparing it
43against the rendered image at the end of each iteration.
