Extension discovers tests but does not run them when Vitest is installed above the root

[roryschadler]

Describe the bug

I have a monorepo¹ which has two components, a Python tool and a TypeScript project. I've installed vitest in the TypeScript project, which isn't the root of the repo, and when vitest is run from the command line in that subdirectory, it works fine.

This extension does discover the tests just fine², but will not run them if I click the run button on the top level of the tree (typescript-project in the screenshot below).

It will run them if I click the run button for client or server, which I've confirmed by setting up a side effect for the test and seeing it occur. But it will not report the test results in this case.

I'm running the latest pre-release version of this extension (0.5.6 as of now). Thank you all for looking into this, I really appreciate it!

Can you add steps on how to install dependencies in your reproduction, please. Currently I see this error when running yarn test in typescript-project folder:

Error: Cannot find package 'happy-dom' imported from /vitest-non-root-monorepo/typescript-project/node_modules/vitest/dist/vendor/index.GVFv9dZ0.js

Fixed it. Turns out I had an old global yarn installed. The error should be fixed by 204d15b

[roryschadler]

Thanks for the quick turnaround @sheremet-va! I confirm that v0.5.7 resolves almost all of this issue. The only remaining issue is

This extension does discover the tests just fine, but will not run them if I click the run button on the top level of the tree (typescript-project in the screenshot below above).

Would you like me to open a separate issue for that?

[sheremet-va]

Oh, I didn't notice that, sorry. So, it doesn't run all tests or all in a folder?

[roryschadler]

As far as I can tell, it doesn't run any tests. I'd expect it to run all the tests under the typescript-project folder. Clicking run on the client or server level will run all tests under client or server respectively, as expected.

I've just pushed a commit to that reproduction, which adds a side-effect to one of the tests. When I click run on the server level, a file is created and test results are reported. When I delete that file, then click run on the typescript-project level, no file is created and no results are reported

[sheremet-va]

Hm, this is actually a bug in Vitest:

This happens because the filter checks the relative path, but typescript-project is outside of the root, so it becomes ../. Please open an issue in Vitest, - I am already working on a fix there.

[roryschadler]

Ah, thanks for digging into that! I'll do that later today. Could you please share the underlying vitest command that's being run in your screenshot? I can't reproduce that error running just yarn test in vitest-non-root-monorepo/typescript-project.

[sheremet-va]

I can't reproduce that error running just yarn test in vitest-non-root-monorepo/typescript-project.

I didn't change anything. You need to specify the full path to typescript-project with a slash at the end.
