Testing stores while accessing other store actions

[Oleksii14]

Store example:

...
actions:  {
 test() {
  const store2 = useStore2()
  store2.test()
 }
}

Unit test:

it('calls the action from another store', () => {
 const pinia = createPinia()
 const store2 = useStore2(pinia)
 store2.test = jest.fn()
 const store1 = useStore1(pinia)
 store1.test()
 
 expect(store2.test).toHaveBeenCalled()
})

Result:

Expected number of calls: >= 1
Received number of calls: 0

Have you tried the experimental creatingPinia()?

• https://github.com/posva/pinia/blob/v2/packages/testing/src/testing.spec.ts
• https://pinia.esm.dev/cookbook/testing.html#unit-testing-a-store

Does createTestingPinia exist in v0.5.4? It seems there is no exported createTestingPinia from 'pinia' module

[posva]

It will be in its own package, it's v2 only but it supports Vue 2 and Vue 3

[Oleksii14]

Can you provide the name of this package?

[posva]

The reason it doesn't work on 0.5.x is that that version doesn't use effectScope() and stores are partially recreated, so it's not possible to spy on actions by overriding them

[posva]

the package is @pinia/testing, it exists now
