Test code:

describe('test', () => {
  it('tests', async () => {
  });
});

I have tried many different tests I could run under mocha, but this is the simplest that fails.

Starting with mocha-parallel-tests -R xunit --timeout 10000 --slow 1000 tests/*.test.js

I started to see this after upgrading Mocha to v8.x.

@mastermatt out of interest, mocha@8 supports parallel mode, does it work for you?

[mastermatt]

Using the parallel mode out of the box in mocha 8 isn't straight forward in my case. I'm moving in that direction, but I was hoping to continue using mocha-parallel-tests in the mean time.

Any updated on this issue @1999 ?
