Describe the bug

I want to be able to merge the coverage generated by Playwright for each tests into one.
I have an issue using nyc to merge and generate the reports after the conversion to istanbul (as described by documentation).

I don't know if this is linked to coverage generated by Playwright or the other tools.

I am able when using other tool, to instrument the tests and to extract the coverage, to generate coverage but not in case of Playwright tools.

After cloning the repo run:
npm install; npm run e2e:playwright

to reproduce the issue.

Error message is:
"Invalid file coverage object, missing keys, found:path,all,statementMap,s,branchMap,b,fnMap,f"

Indeed the file generated have empty path which leads to the error.

Thx for the help.

Hi, since you are using @playwright/test I would recommend that you wait for #7030. This gives you coverage report out of the box for all the browsers and not only or Chromium.

Closing as it gets addressed in #7030.
