Reference: https://github.com/microsoft/playwright/blob/main/tests/bidi/README.md

Steps:
* Clone Playwright: https://github.com/microsoft/playwright
* Run `npm install` (or `npm run clean` before in case of errors during installation)
* Run `npm run build` (as well each time you make modifications to the source)
* Run `npm run watch` (optional, to start the watch mode for incremental compilation)
* Use `DEBUG="pw:browser"` to log the output of Firefox to the terminal console
* Use `DEBUG="pw:protocol"` to log the usage of Juggler and CDP protocol to the terminal console
* Use `PWDEBUGIMPL=1` to see a full stack of where the error was thrown
* Use `PWTEST_FIREFOX_USER_PREFS='{"remote.log.level":"Trace"}'` to set custom Firefox preferences
* Use `PWTEST_USE_BIDI_EXPECTATIONS=1` to enable custom expectations (e.g. skipping tests that timeout)
* Use `BIDI_FFPATH=/%path%/%to%/%firefox%/%binary%` to use a custom build of Firefox
* Use `CI=1` to get test results written to `test-results/report.json`
* Update the `./expectationReporter` in `tests/bidi/playwright.config.ts` with `rebase: true` to update the expectation files
* Run tests: `npm run biditest -- --project='moz-firefox-%train%*' [%path%/%to%/%tests]` (train is one of `nightly`, `beta`, or `stable`)

Further to run only individual tests you can also use `it.only` (that prevents requiring the path as mentioned above)

Debug Playwright test and core code with VSCode:
* Run `npm run watch` to let the compiler create the source maps on file changes
* Add `.only` to the test (see above) that you want to debug
* Set your wanted breakpoint(s)
* Open the `Javascript Debugger Terminal` via the command palette (`Cmd+Shift+P`)
* Run the test command as listed above with the Javascript Debugger Terminal
