fastest-jest-runner's Issues

Crashes with ../src/node_platform.cc:214:void node::WorkerThreadsTaskRunner::Shutdown(): Assertion `(0) == (uv_thread_join(threads_[i].get()))' failed.

I setup the runner in https://github.com/EvHaus/test-runner-benchmarks to benchmark it against jasmine and jest. It runs the tests, but crashes with:

exit from root process!!!!! 0
Tests left:

Code Coverage

Hey I just wanted to enable codecov.io and was debugging for 2 hours why we've seen 0 hits across our covered files. Now I noticed when I turn off fastest-jest-runner it reports correctly. Has someone achieved to get a functional coverage report using fastest-jest-runner?

Some tests crashing on macOS due to fork()

Hey there! I came across this amazing repo while investigating how to speed up our memory hogging test suite. I am completely flabbergasted by the ingenuity behind this runner. Really well done.

Running my tests on a Linux machine is no problem. All tests run fine and it seems the processes correctly fork.
Running the same tests on macOS 13.2.1 however makes some tests fail with the following error:

objc[59483]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.

I am not too familiar with macOS internal workings but judging by this blog post: http://sealiesoftware.com/blog/archive/2017/6/5/Objective-C_and_fork_in_macOS_1013.html

It seems to be related on how macOS handles thread safety of forked child processes. Not sure why this is not a problem on any other Linux Distro though.

Exporting OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES before running the tests fixed it for me but i am unsure if this would be the best approach.

Is this behaviour something that should be fixed here with one of the suggestions in the link i shared above, or can this be safely ignored with the env var?
