|  | To run OpenGL ES 2.0 conformance tests, do the following: | 
|  | (These require access to Google-internal sources.) | 
|  | 1. Generate build files: | 
|  | "python build/gyp_chromium gpu/gles2_conform_support/gles2_conform_test.gyp" | 
|  | or set "GYP_DEFINES=internal_gles2_conform_tests=1" and rebuild your | 
|  | projects using your standard method. Example: | 
|  | "GYP_DEFINES=internal_gles2_conform_tests=1 gclient runhooks" | 
|  | 2. Build any of the two targets: | 
|  | - gles2_conform_test_angle which tests ANGLE | 
|  | - gles2_conform_test_native which tests command-buffer service | 
|  | - gles2_conform_test_windowless which tests command-buffer service on most platforms | 
|  | - gles2_conform_test_pepper will be added later | 
|  | 3. Run the targets as: "<path to>gles2_conform_test_native -noimagefileio | 
|  | -run=<path to>third_party\gles2_conform\GTF_ES\glsl\GTF\mustpass.run" |
