[Piglit] [PATCH 1/5] gles2: add sanity test

Tom Gall tom.gall at linaro.org
Mon Dec 17 15:34:05 PST 2012


new tests/spec/gles-2.0 directory and infrastructure to build
  initial testcase and add gles-2.0 as part of all.tests

new gles2 sanity test which very simply renders a triangle fan and
  validates it was rendered correctly via
  piglit_probe_rect_rgba
