Move "test.dart" (well, most of its contents) into pkg/test_runner.
I don't like having a large volume of Dart code sitting under tools/ where it is hard to analyze, lint, test, and reuse. Also, eventually we want to merge test.dart and test.py. This seems like an easy mostly mechanical first step. All I did was: 1. Move the contents of tools/test.dart to pkg/test_runner/lib/test_runner.dart. (That's not a great file name since we already have pkg/test_runner/bin/test_runner.dart, but it was the best I could come up with. 2. Copy tools/bots/results to pkg/test_runner/bot_results.dart. I don't like duplicating this, but there are other scripts under tools that import the old location. Eventually, we should have those scripts import it from package:test_runner/bot_results.dart, but I didn't want to do that here since I'm not familiar with those other scripts. 3. Make tools/test.dart import and forward to pkg/test_runner/lib/test_runner.dart. 4. Fix any linter and type errors. The test_runner package has a bunch of strictness checks and lints enable to keep it cleaner. 5. Run dartfmt --fix to format and get rid of "new", etc. Change-Id: Ifc89817508d3fc147fa78dbc6744d547aeaf4c55 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/155240 Commit-Queue: Bob Nystrom <rnystrom@google.com> Auto-Submit: Bob Nystrom <rnystrom@google.com> Reviewed-by: Jonas Termansen <sortie@google.com>
