Hi Joey, Thanks for raising this question. As far as I know there are a few tests exercising on twister2 runner:
- https://github.com/apache/beam/actions/workflows/beam_PostCommit_Java_ValidatesRunner_Twister2.yml - https://github.com/apache/beam/actions/workflows/beam_PostRelease_NightlySnapshot.yml?query=event%3Aworkflow_dispatch++. The latter one is part of release validation workflows, which means itshould work on the latest Beam release at least for basic features exercised by these tests. However there is indeed a proposal to decommission unmaintained runners in the next major release (Beam 3), for example https://github.com/apache/beam/issues/35448. Given the status of upstream trepo, twister2 runner could also be in scope. Feel free to raise a GitHub Issue for proposal.
