How to run pytest-watch inside docker

[realmhamdy]

Hello

I thought this was a no-brainer and will just work out of the box. But for some reason, ptw won't rerun tests inside docker when code changes, even if it works fine on the host.
Here's a minimal repo that reproduces the issue for me.

##Steps to reproduce:

1. docker build -t ptw-docker .
2. docker run -v /path/to/repo/code:/app
3. The output indicates the test failed.
4. Modify test_sample.py and see tests are not rerun.

If you run with -it, does that help? I have no problem running with docker-compose

I'm currently having some issues when running two containers concurrently FWIW
