Describe the bug

I am just upgraded the aws-amplify from v5 to v6. Seems subscriptions working fine. I tried to create mock response for those subscriptions. In v5 I used spyon to create mock response. jest.spyOn(API, "graphql").mockImplementation(() => { return of(mockResponse); });

But in V6 seems API is removed. I am not able to mock those subscription.

Expected behavior

Mock should work with v6

Reproduction steps

create spyon for subscription

Hi @lingomksr the new API for graphql clients in V6 is from generateClient to initialize a client. You should be able to mock client.graphql instead of API.graphql

https://docs.amplify.aws/react/build-a-backend/data/connect-to-API/#generate-the-amplify-data-client

Let me know if that helps!

HI @chrisbonifacio,

I tried to use like this

const amplifyClient = generateClient();
    const apiSpy = jest.spyOn(amplifyClient, "graphql").mockImplementation(() => {
      return of(mockResponse);
    });

But its not throws type mismatch build error!

Hi @lingomksr , I would recommend checking out how we test subscriptions in our library:

https://github.com/aws-amplify/amplify-js/tree/main/packages/api-graphql/__tests__

If that doesn't help, I'll try and see if I can get you some feedback and/or guidance on your tests.

Also, can you please share the error message you're seeing?
