[BUG] VSCode Extension Test explorer not running any tests: "no tests found" "1 error was not a part of any test, see above for details"

[Wilhop]

Context:

• Playwright Version: 1.26.0
• Operating System: Windows
• Node.js version: v16.13.1
• Visual Studio Code version: 1.71.2
• Playwright for VSCode extension version: 0.2.10
• Browser: [e.g. All, Chromium, Firefox, WebKit]

Reproducable repo:
https://github.com/Wilhop/PlaywrightExtensionRepro

1.I have the VSCode extension "Test explorer" open
2.I click on "Run test" button on any of the following tests: "plainLogin.spec.ts" or "Online.spec.ts"
3.It does not run any tests. Check console
no tests found.
1 error was not a part of any test, see above for details

Here is the log from the terminal:

Running 0 tests using 0 workers
Error: login\plainLogin.spec.ts:7:12: Playwright Test did not expect test.describe() to be called here.
Most common reasons include:
- You are calling test.describe() in a configuration file.
- You are calling test.describe() in a file that is imported by the configuration file.
- You have two different versions of @playwright/test. This usually happens
  when one of the dependencies in your package.json depends on @playwright/test.

We were facing the same issue in Windows Playwright 1.26.0, after updating the Playwright version to 1.26.1. We have not observed this issue.

Updating Playwright to version 1.26.1 solved the issue, I appreciate your help @Mallikarjunkrs !

I'll close this, as it seems upgrading to the latest version is the answer.

@Mallikarjunkrs how do I debug no tests found?

I want to match slices/**/tests/**/*.js for slices/${folder}/tests/${all subfolders}, there about 10 submodules

• ls slices/**/tests/*.js prints just first level, but match occurs
• Tried to inspect pw /tests/ and found no test about glob pattern
• DEBUG=* npx playwright test prints NO info about matched files

If no debugging is possible, could you please point out where the hell in pw source code match occurs? I want to debug my case

Impact: integrating pw into my enviroment blocked
