Hopefully this is fixed in v3.1.4. Please reopen if not.

Switching from setImmediate
to process.nexTick
does make a few of the tests fail. Not sure why, I haven't had a chance to look into it further. But IIRC it was difficult to get all of the asynchronous stuff working correctly, and I think even now there are some rare edge cases where it doesn't work quite right. Very finicky stuff. So I'm a little scared to change it :)

I tried using queueMicrotask
but got a few timeout in tests (I guess the same ones you got with process.nextTick
). I think the difference is that setImmediate
is a macrotask, but process.nextTick
and queueMicrotask
queue microtasks, which behave differently.
I also tried using setTimeout
and with this, all tests are passing. The downside of setTimeout is that in browsers it may be delayed more, especially when nested. But is that a problem for this package, as it will run in a test environment? That would remove the need of the polyfill for setImmediate
, reducing the complexity.
But anyway this doesn't solve the problem with jest's fake timers, because they also mock setTimeout
obviously. Instead of calling setImmediate
or setTimeout
, we'd need to call the real functions, probably using some magic with jest
functions like outlined above.
For now I'm not blocked anymore in our project, as I removed the fake timers from the tests that were using this library.
