Vitest and Pinia reactivity not working when running multiple tests

[wasimTQ]

I'm testing my custom store built with createGlobalState from vueuse. I'm using a watcher to watch for changes in pinia's getter to manipulate value in my store.

For some context:

• cardExpandedDialogStore is a pinia store
• cardNavigation is a custom store
• cardExpandedDialogStore.open() when I call this function it modifies the store values dialogIsVisible, expandedCard that's used inside the custom store to manipulate values.

The problem is it works perfect when I'm only running that test suite with it.only. And not working when running multiple test suites.

When running the single test suite alone, the response for
console.log(currentIndex.value, currentCardId.value) // These are from cardNavigation is 1 'd66ee8a8-c650-42b7-bbe0-7c8761473b45'.

But when running multiple test suites other tests are passing but only two tests that calls the open function is failing and the console log of the above in 0

I know I should've explained it better. But I don't know how. And I can't share much of codes that's protected by NDA. Let me know if you can help me solve it.

This seems to be related to vueuse, not pinia. BTW you shouldn't use a global state with pinia as pinia already makes its state global. I suspect the global state you are creating is being reused across tests. With pinia, each each test should have its own createPinia() to ensure they run with their own fresh state https://pinia.vuejs.org/cookbook/testing.html#testing-stores

Yeah I have it set up like this in beforeEach. I couldn't really point out a problem there.

I also reset the stores I'm using in afterEach.

The pinia's reactivity is updated but it doesn't seems to work on the custom composable.

Seems to be not working in some instance. So I worked up another work around.

I thought of do it like integration testing. But mocked the function from the custom store instead.

Instead of resetting stores, use a new pinia instance like shown in docs
