feat(test): support unstubbing actions

[CyberAP]

This change makes it possible to unstub actions when using stubActions: true in createTestingPinia. To do that you have to call mockRestore on the action.

createTestingPinia()

useMyStore().someAction.mockRestore()

// this calls an actual implementation
useMyStore().someAction()

The support for unstubbing is provided only for jest and vitest.

Thanks a lot for this! I'm reworking

• feat: add selective action stubbing support #3040
• to have Allow stubbing specific actions only #2970 implemented

The approach you want should already be doable with type support using the helper mentioned in docs. It depends on your testing framework

[CyberAP]

@posva this is somewhat different. We could stub specific actions before that:

createTestingPinia({ stubActions: false })
actionsToStub.forEach(action => jest.spyOn(useMyStore(), action).mockReturnValue())

What we can't do is stub everything but unstub specific actions.

You can unstub specific actions, I just tested it. But now you can also pass a function to stubActions and return a boolean to decide wheather to stub or not. It should fit any advanced cases
