46Description:
47
48Test creates two images and initializes them to random data. Both images have
49always npot size and texture images are always created so that they are mipmap
50complete. Random data is always generated so that it is valid for both formats
51e.g. no invalid ASTC blocks or NaNs exist before or after copying.
52
53Multiple copies are performed per test case. Texture levels 0, 1 and last level
54are used as source and destination levels. For each texture level top left and
55bottom right corners are used as source rectangle and destination rectangle.
56Also npot offset in the middle of the image is used. Some of the copied
57rectangles are npot size.
58
59Each test case does copying in two different ways. First they create images,
60use them for rendering, copy and perform verification. Second time they create
61images and immediately copy them without rendering and finally verify image
62contents.
63
64Instead of trying to isolate different smaller features and testing them
65separately, these tests try to test multiple cases for each format as there
66would be huge number of tests and it would take too long to run more than one
67case for each format and image combination.
