Message : Fix import paths for //scripts/run_gtest_angle_test.py. We added run_gtest_angle_test.py in a86c854, but didn't actually check that it worked :(. This CL adds the missing sys.path imports needed to find the rest of the Chromium test script modules. Bug: chromium:816629, angleproject:3162 Change-Id: I4c381bda334df4d2e648aab65ca4cc0310d840bf Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2283694 Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Dirk Pranke <dpranke@google.com>

"""Runs an isolated non-Telemetry ANGLE test.

The main contract is that the caller passes the arguments:

  --isolated-script-test-output=[FILENAME]
json is written to that file in the format:
https://chromium.googlesource.com/chromium/src/+/master/docs/testing/json_test_results_format.md

Optional argument:

  --isolated-script-test-filter=[TEST_NAMES]

is a double-colon-separated ("::") list of test names, to run just that subset
of tests. This list is parsed by this harness and sent down via the
--gtest_filter argument.

This script is intended to be the base command invoked by the isolate,
followed by a subsequent non-python executable. For a similar script see
run_performance_test.py.
