[Question] Testing with Jest/Vitest

[kwiat1990]

Hi Matt, have you tried to unit test the theme-provider? I'm stuck a little bit on the following error from Vitest:

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.

which I can't really track down and fix. I have though it have something to do with throw Error() inside useTheme hook but after some refactoring Vitest still throws the above error.
