How to handle hoisted mocks

Let’s take the following code snippet:

import { mockDeep } from "jest-mock-extended";
// ... other imports

jest.mock("./someObject", () => ({
  someObject: mockDeep<InstanceType<SomeClass>>(),
}));

This would fail because jest hoists jest.mock above all the imports and so mockDeep would be undefined.

How do I solve this problem? And would it be worthwhile adding documentation on how to do this?

Probably worth adding to docs… but you can do this:

import { mockDeep } from "jest-mock-extended";
// ... other imports

jest.mock("./someObject", () => {
    const nonHoistedMockDeep: typeof mockDeep = jest.requireActual("jest-mock-extended").mockDeep;
    return {
      someObject: nonHoistedMockDeep<SomeClass>(),
    };
});

@toshi38 this is absolutely worth adding to the docs, this is a scenario that we would encounter quite frequently.

Closing this issue as resolved, but yes definitely worth adding to the docs!
