Datastore Amplify Mock Support

[diegoconcha]

Is this feature request related to a new or existing Amplify category?

No response

Is this related to another service?

Datastore

Describe the feature you'd like to request

My team and I spent a week getting excited about and integrating datastore into our app only to find out when trying to test it locally that it doesn't work with amplify mock so we ended up having to rip it out. This would be an awesome improvement as testing on the cloud is slow especially between deploys.

Describe the solution you'd like

We're approach agnostic as long as amplify mock works with datastore :).

Describe alternatives you've considered

Not using datastore and having to wrangle app state and backend state manually.

+1. I'm surprised that this is not supported. What's the best practice for developing with Datastore locally? If we need to rely on a cloud Dev environment, it's slow and not really cost-effective.

What if there are multiple developers working on the same project? Does each of them need to create a cloud environment for their branch? Is this a cost-effective approach?

Keen to learn more about this 🙏

Any update on this? mocking and testing my DataStore app locally would be very useful

[talaikis]

jest.mock('aws-amplify/datastore', () => ({
  DataStore: {
    configure: jest.fn()
  },
  initSchema: jest.fn().mockImplementation((schema) => ({
    Update: jest.fn(),
    Upstream: jest.fn(),
    Message: jest.fn()
  })),
  DISCARD: {}
}))

etc.
