Describe the bug

I have other code I am using for this, but I was able to reproduce the issue with the default example tests provided here that Playwright provides when downloading it. I am running my tests on TeamCity. I have a Linux VM with a TeamCity build agent Docker container. I am also using the Docker container from Playwright to run the tests in. So far, the tests run fine in Chromium and Safari. However, I get the following error when trying to run them in Firefox: Timeout of 30000ms exceeded while running fixture “browser” setup. at /opt/buildagent/work/6f7a18f2c8f56a5c/PolicyTechAutomationTests/tests/smoketestshould.spec.ts:94:6 That line in my code (which is different than the code pasted here) is: test.beforeAll(async ({ browser }) => { I am able to run these tests using Firefox on my local environment without issue. It is almost as if the Playwright Docker container is acting like Firefox does not exist.

[KenjiTakahashi]

@aslushnikov Installing from inside the container does not fix the issue for me. I did some further experiments. Using the same example project code from npm init, but removed node_modules and package*json.

docker run --rm -it -v $(pwd):/code/t/ mcr.microsoft.com/playwright:v1.22.2-focal /bin/bash

Then inside the container:

1. cd /code/
2. npm i @playwright/test
3. npx playwright test -c /code/t/playwright.config.ts --project firefox -> This works fine.
4. cd /t/
5. npx playwright test -c /code/t/playwright.config.ts --project firefox -> This fails.

Then I did the “opposite” (in new container):

1. cd /code/t/
2. npm i @playwright/test
3. npx --prefix /code/t/ playwright test -c /code/t/playwright.config.ts --project firefox -> This fails.
4. cd ..
5. npx --prefix /code/t/ playwright test -c /code/t/playwright.config.ts --project firefox -> This works.

So it looks like the trigger is cwd being on a bind mount. Doesn’t matter if the code or deps are also bind mounted or not. But why that is, I can’t really tell. And why it only fails for Firefox? Sth wrong with how Firefox handles files in bind mounted dirs?

[jkilada]

Thanks @KenjiTakahashi for your research. I was able to resolve the issue in a similar manner by ensuring cwd was outside of the bind mount before invoking the tests.
