Playwrigth tests on multiple browsers

This repo is a showcase how to run Playwright tests on multiple browsers inside a nix-shell.

On my Mac, the tests run just fine on all three browser types:

$ nix-shell
[nix-shell:~/work/playwright_test]$ python test.py
Running test on chromium
Running test on firefox
Running test on webkit

However, they fail on Ubuntu-based GitHub Actions:
