Due to recent Chrome infra changes in
https://chromium-review.googlesource.com/c/472290/
tests running on swarming are now assumed to emit JSON results
or will be marked as failing. This requires us to use our
gtest-parallel wrapper for all our Swarming tests
(or implement the --isolated-script-test-output flag, which
normally only is implemented by the Chromium test launcher).
The low_bandwidth_audio_test can actually run in parallel,
so just change that.
The webrtc_nonparallel_tests cannot, so this CL changes MB
to pass --workers=1 flag to gtest-parallel, which makes the
tests run in sequence. This adds a little confusion but the root
problem is really that our gtest-parallel script [1] does a lot more
than just running the tests in parallel these days, so it should
probably be renamed.
Also make sure gtest-parallel-wrapper.py [2] consumes the
--isolated-script-test-chartjson-output flag (unused) so we don't
pass it on to the test executable.
