Can you add a test that does not look into _writableState? Why are you doing this change?

sure, I will add a new test to address it, thanks!
Why are you doing this change?
Do you mean the change to the test? If so, it is because when the callback function is called in stream.finished it won't wait for the callback in the writable._write (if any async action is performed) and one of the indication is stream._writableState.pendingcb is not 0.

I have expanded the test to make sure the cb in _write is called before the cb in finished is called. PTAL @mcollina 🙏
Make sure the callback in `write` is called before the callback in finished
