[BUG] Show `yarn` instead of `npx` in show-trace error message

System info

• Operating System: [Windows 11]
• Browser: [Chromium]
• Other info:

Steps

• Run a test in a yarn environment

Expected

The log message on test fail should be: yarn playwright show-trace "test-results\page-01 - appointments-Create-chromium\trace.zip"

Maybe a solution would be that when a yarn.lock file is found, it shows yarn instead of npx.

Actual

It prints: npx playwright show-trace "test-results\page-01 - appointments-Create-chromium\trace.zip"

Looking at the lock file looks like too much hassle, also won't work without the lock file. If yarn allows detecting it explicitly, we can follow up with a fix. For now marking it as non-actionable.

Thanks for looking at this. At this moment, I don't know a way to explicitly know when yarn or npm is used without looking at the lockfile unfortunately.

Same here, that's why we can't act on the issue. Closing as non-actionable.
