Flaky test?

[kikuomax]

Overview of the problem

Buefy version: [0.2.0]
Vuejs version: [3.3.10]
OS/Browser: macOS/Vitest

Description

A GitHub Actions job for verification (verify.yml) failed with the following error:

⎯⎯⎯⎯ Unhandled Rejection ⎯⎯⎯⎯⎯

⎯⎯⎯⎯⎯⎯ Unhandled Errors ⎯⎯⎯⎯⎯⎯
ReferenceError: window is not defined

 ❯ Proxy.<anonymous> src/components/autocomplete/Autocomplete.vue:607:37
Vitest caught 1 unhandled error during the test run.

This might cause false positive tests. Resolve unhandled errors to make sure your tests are not affected.

    609|                     this.updateAppendToBody()

This error originated in "src/components/autocomplete/Autocomplete.spec.ts" test file. It doesn't mean the error was thrown inside the file itself, but while it was running.
This error was caught after test environment was torn down. Make sure to cancel any running tasks before test finishes:
- cancel timeouts using clearTimeout and clearInterval
- wait for promises to resolve using the await keyword

This should not be a problem of the library itself.

Steps to reproduce

Difficult to reproduce; when I re-ran the tests, it did not happen. Run unit tests repeatedly until you face it.

Expected behavior

Any unhandled rejection error should not happen.

Actual behavior

An unhandled rejection error happened.

It happened again!

What branch were you on? Dev?

I was looking through that pipeline's logs and can't find the error being logged

@wesdevpro On dev, but I reran the failed jobs, and they passed. That's why you could not find the error.
