@MoLow is this ready for review? At a minimum, it looks like there are linter issues.

@nodejs/test_runner ready for review

lib/internal/test_runner/runner.js

We should probably update the doc of --watch-path and --test to clarify they can't be used together

node/doc/api/cli.md

Lines 1214 to 1216 in f1e9382

    
           Starts the Node.js command line test runner. This flag cannot be combined with 
        
           `--check`, `--eval`, `--interactive`, or the inspector. See the documentation 
        
           on [running tests from the command line][] for more details.

node/doc/api/cli.md

Lines 1610 to 1611 in f1e9382

    
           This flag cannot be combined with 
        
           `--check`, `--eval`, `--interactive`, or the REPL.

We could add an entry to the history of --watch and --test to say that now they can be used together.

Could we add a test to ensure watching ESM works? And maybe even ESM+CJS?

@ErickWendel you were asking about this

aduh95

I don't know if you missed it in my previous review, I was asking if it would be possible to add tests for ESM (i.e. does dependencies loaded though import() from a CJS files are picked up)

Going to rebase on top of #45348 to avoid conflicts

LGTM if the CI is happy
