From the full log it looks like something is quite wrong in the test, it keeps getting stuck at tons of Updating /home/iojs/node-tmp/.tmp.2479/dependency.js until the 2 minute timeout is reached (my guess is it has more to do with how the test is written)

is anyone able to reproduce with tools/test.py --repeat=1000 test/parallel/test-runner-watch-mode.mjs? on my machine it passes smoothly

I'm also unable to reproduce on macOS (Apple Silicon)

The flakes in the CI only show up in Linux ARM and Linux + shared library. I am guessing using a similar setup may help reproducing the issues. Or you can try using the the CI boxes.

Looks like this also comes up to people running Ubuntu 22.04 locally too https://github.com/nodejs/node/issues/49513
