19    Occlusion query stress tests
20
21Tests:
22 + dEQP-GLES3.stress.occlusion_query.*
23
24Includes:
25 + Uses primitives drawn with GL_TRIANGLES
26 + Uses query target ANY_SAMPLES_PASSED
27
28Excludes:
29 + Occlusion query result verification based on framebuffer
30
31Description:
32
33Occlusion query stress tests generate large amounts of occlusion queries
34in order to test implementation's ability to handle them. First a
35specified number of occluding triangles are drawn. Then the occlusion
36query is started, specified number of target triangles are drawn and the
37occlusion query is terminated. After all occlusion queries and triangle
38draws are executed, glFinish() is called and all query results are read.
39
40Actual query result values are not verified - only trouble-free result
41retrieval is tested. Query result correctness can be implemented later
42by inspecting framebuffer contents.
