There's going to be mostly nitpicky style stuff here. The tests I've read through so far look like really good additions to the coverage. The only thing I don't really like about the testing methods in a few of these is that they just do GetTexImage() and look at those those values, rather than rendering them to the screen and probing the result in the window system. I think that one of the great strengths of piglit compared to other graphics test suites is that the results are easily visible when you want to debug a testcase. GetTexImage() also generally means that our tests are exercising a less common and useful path in the driver compared to what applications are going to be doing (actual rendering with the textures). I'm not going to block the tests over this, though. > diff --git a/tests/spec/arb_texture_view/texsubimage-levels.c > b/tests/spec/arb_texture_view/texsubimage-levels.c > new file mode 100644 > index 0000000..6457393 > --- /dev/null > +++ b/tests/spec/arb_texture_view/texsubimage-levels.c > @@ -0,0 +1,129 @@ > +/* > + * Copyright © 2014 Intel Corporation > + * > + * Permission is hereby granted, free of charge, to any person obtaining a > + * copy of this software and associated documentation files (the "Software"), > + * to deal in the Software without restriction, including without limitation > + * the rights to use, copy, modify, merge, publish, distribute, sublicense, > + * and/or sell copies of the Software, and to permit persons to whom the > + * Software is furnished to do so, subject to the following conditions: > + * > + * The above copyright notice and this permission notice (including the next > + * paragraph) shall be included in all copies or substantial portions of the > + * Software. > + * > + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR > + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, > + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
