@matanlurey:

Is there a deterministic (by humans) way of mapping a package/foo/test/foo_test.dart to the task and shard it is executing on? I'd settle for "I know the task, tell me the shard" if that is all we have.

For example, imagine the query:
"I am a test owner of package/foo/test, and I want to see if foo_test.dart is running slowly"

@christopherfujino:

There is a deterministic way, but it's not easy. We could add a special flag to test.dart though, that doesn't actually run any tests but prints out what tests would have run on which shard. this seems useful
