Each primitive is tested using a single 45e5c31af7Sopenharmony_ci(generated) attribute array, multiple attribute arrays, instanced 46e5c31af7Sopenharmony_ciattribute array (instance divisor > 0) and with a non-array current 47e5c31af7Sopenharmony_ciattribute. 48e5c31af7Sopenharmony_ci 49e5c31af7Sopenharmony_ciDrawArraysIndirect firstVertex cases draw random triangles using 50e5c31af7Sopenharmony_ciglDrawElementIndirect with firstVertex > 0 and compare results to a 51e5c31af7Sopenharmony_cigenerated reference image. 52e5c31af7Sopenharmony_ci 53e5c31af7Sopenharmony_ciDrawElementsIndirect index array cases draw random triangles using 54e5c31af7Sopenharmony_ciglDrawElementIndirect with index types of unsigned byte, short and int 55e5c31af7Sopenharmony_ciwith both firstIndex = 0 and firstIndex = 1 and compare results to 56e5c31af7Sopenharmony_cigenerated reference images. 57e5c31af7Sopenharmony_ci 58e5c31af7Sopenharmony_ciDrawElementsIndirect baseVertex cases draw random triangles with index 59e5c31af7Sopenharmony_citypes of unsigned byte, short and int using both positive and negative 60e5c31af7Sopenharmony_cibaseVertex values and compare results to generated reference images. 61e5c31af7Sopenharmony_ci 62e5c31af7Sopenharmony_ciInstanced draw cases draw a grid by instancing a single tile. The result 63e5c31af7Sopenharmony_ciis verified by simply searching for background colored (black) pixels in 64e5c31af7Sopenharmony_cithe result image. Resulting image should not contain any background 65e5c31af7Sopenharmony_cicolored pixels. 66e5c31af7Sopenharmony_ci 67e5c31af7Sopenharmony_ciNegative cases test try to issue a bad indirect draw command expecting an 68e5c31af7Sopenharmony_ciINVALID_OPERATION. Bad commands tested are commands with bad alignment, 69e5c31af7Sopenharmony_cicommands only partially in the DRAW_INDIRECT_BUFFER buffer, and commands 70e5c31af7Sopenharmony_cinot even partially in the DRAW_INDIRECT_BUFFER buffer. 71
