I'm having a problem with ng test and Angular v21

Start by reproducing the failure with ng test and with pnpm run test in the reported Windows, Angular CLI 21.0.1, Node.js 24.11.1, and pnpm 10.24.0 environment. Compare the two command paths and capture the underlying error; done means the test command reports a useful failure without closing the terminal.

Which @angular/* package(s) are the source of the bug?

Don't known / other

Is this a regression?

No

Description

Let me explain my problem. I'm trying to run tests using ng test, but I don't know why it suddenly closes the terminal and I don't get any errors. If I run pnpm run test or pnpm test using pnpm run test, I get these errors:

ELIFECYCLE Test failed. See above for more details.

I've searched on Google but haven't found anything about this issue.

I'm using a Windows environment.

Please provide a link to a minimal reproduction of the bug

No response

Please provide the exception or error you saw

When I launch ng test, my terminal immediately shuts down. But if I run it via `pnpm run test`, I get this error ELIFECYCLE Test failed. See above for more details.

Please provide the environment you discovered this bug in (run ng version)
