You should consider switching these tests to use file_test_runner. It doesn't require recompiling when adding a test: https://github.com/denoland/file_test_runner (https://david.deno.dev/posts/file-test-runner/)

Sounds interesting. Does it support listing tests without running them? IIRC it was required for some reason.

swc-bump:

• swc_core
• swc_ecma_codegen

Yeah, the collection module allows for that: https://docs.rs/file_test_runner/0.7.2/file_test_runner/collection/index.html

It's two steps—collect and then run.
