Jest Testing with async errors

[nathanthibert]

I have a test where I'm rejecting a service call. We can use the documentation example.

 async registerUser(login, password) {
      try {
        this.userData = await api.post({ login, password })
        showTooltip(`Welcome back ${this.userData.name}!`)
      } catch (error) {
        showTooltip(error)
        // let the form component display the error
        return error
      }
    },

How do we test the return value of the error? I assume this hooks into the $onAction(({onError})=>{}). How do we test this in our store and or in our component?

You can instantiate a regular store in a test and call the action and check the returned value:

expect(await store.registerUser(...)).toEqual(...)

I love how easy this framework is. Amazing!
