@m-radzikowski any update on this?

I'm trying to mock cloudfront waitUntilInvalidationCompleted. I think this would helpful.

I also see there is the callsFake method but I haven't figured out how to get that working, if that's even the way to go. Any suggestions would be greatly appreciated.

No, it's not supported directly by the library. The best approach is to mock the waitUntilInvalidationCompleted function with Jest or other lib, like this: https://jestjs.io/docs/mock-functions#mocking-partials

Thanks for the quick response! I managed to mock successfully as you suggested.

For future reference, the workaround I found:

jest.mock('@aws-sdk/client-cloudfront', () => ({
  ...jest.requireActual('@aws-sdk/client-cloudfront'),
  waitUntilInvalidationCompleted: jest.fn(async () => cloudfrontWaiterResponse),
}));
