Recently discovered when adding some evaluation tests, our parallel test runner did not support async mocha tests (either using
done
, or via async functions). This changes the parallel test runner to leverage more of Mocha to actually run the tests in each parallel worker to avoid future inconsistencies.NOTE: This PR includes a private copy of the mocha definitions until such time as DefinitelyTyped/DefinitelyTyped#26396 has been merged.
