Help with stitched schema mocks

[janKozie1]

Hi! I'm trying to write mocks for my API - I've got a frontend app and its requests go through a mock server.
(app - mock_server - real_server). On the mock_server i would like to add new types and extend existing ones.

I've made a simple demo illustrating my issues: https://github.com/janKozie1/graphql-tools-example

Basically:

• I'm not sure how to make stitched schema resolvers use the store properly - the store returns refs, which i imagine have to be resolved by something. I imagine addMocksToSchema does it, but I'm not sure how to use while stitching (https://github.com/janKozie1/graphql-tools-example/blob/591b85614fb3de249a9f2c2f5182729f1aebfc61/mock_server/schema/stitches/index.js#L18)
• I'm not sure how to mock a stitched mutation - https://github.com/janKozie1/graphql-tools-example/blob/591b85614fb3de249a9f2c2f5182729f1aebfc61/mock_server/schema/stitches/index.js#L21 - this does not seem to run, even though the Book.comments defined in the same file does
• I'm not sure how to access variables from field higher - https://github.com/janKozie1/graphql-tools-example/blob/591b85614fb3de249a9f2c2f5182729f1aebfc61/mock_server/schema/mock/index.js#L36 (the variableValues are empty, compared to https://github.com/janKozie1/graphql-tools-example/blob/591b85614fb3de249a9f2c2f5182729f1aebfc61/real_server/index.js#L46, where they aren't)
• I'm not sure how to associate mocked generated values with an entity coming from an external API - https://github.com/janKozie1/graphql-tools-example/blob/591b85614fb3de249a9f2c2f5182729f1aebfc61/mock_server/schema/stitches/index.js#L15 - i know i've got an access to the parent object, which is what my "real api" returns, but how do I associate mocked values with it? (so that querying for the mocked field on the same entity will result in the same values)

Any help will be greatly appreciated!
