Improve GraphQL mocking

Is your feature request related to a problem? Please describe. Right now you need to mock the whole GraphQL response like this https://github.com/mswjs/msw/blob/e31a344332f5951177bb17655a82c7cefe59445e/test/graphql-api/query.mocks.ts

Describe the solution you’d like The idea is to only mock the types and fields that you need in your test

Describe alternatives you’ve considered I’ve been using relay-testing-utils to mock only parts of my GraphQL response https://relay.dev/docs/en/testing-relay-components We can also use graphql-tools mocking approach (https://www.apollographql.com/docs/graphql-tools/mocking/)

Additional context This is based on a twitter discussion (https://twitter.com/sseraphini/status/1264877251587432448) about graphql-mock-api

We’ve shipped support for graphql.operation request handler in msw@0.21.0. Updating to that version should allow you to use that request handler to resolve any GraphQL operation any way you wish (i.e. using an external server).

I’ll close this issue, concluding its scope being graphql.operation support. That is to prevent it from being forever open without a clear milestone. We still have a way to go with enhancing GraphQL support with adding subscriptions and providing other improvements to the experience. Please don’t hesitate to reach out and share your feedback on the GraphQL usage of MSW. You’re awesome.

Agreed. I think the graphql.operation could pretty much cover all cases mentioned here. I see that @garhbod is planning to contribute with a PR, great! I’m happy to help if needed!
