Each test case performs multiple iterations, each consisting 39 of multiple color clears. Parameters, such as color, scissor rectangle 40 or color mask are chosen using deterministic random number generator. 41 42 Results are verified by building a reference image and comparing it 43 against the rendered image at the end of each iteration. 44
