  Message : Re-land "Add new test runner harness." (#2) Re-land #2 changes: * export labels are fixed for the CFI build * crash test disabled because of flakiness and issues with asan Re-land changes: * Unit test is suppressed in ASAN * --deqp-case is fixed * Debug layer errors should correctly work with failure expectations Original message: The ANGLE test harness is a harness around GoogleTest that provides functionality similar to the Chromium test harness. It supports: * splitting a test set into shards * catching and reporting crashes and timeouts * outputting to the Chromium JSON test results format * multi-process execution Unit tests are added in test_utils_unittest.cpp. Bug: angleproject:3162 Bug: chromium:1030192 Change-Id: I71d66a407ea0e53d73cbe75b5b4bfb9e73791534 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1965091 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Jonah Ryan-Davis <jonahr@google.com>
