Passing out-of-scope variable with jest.mock

Question

I have a mock object that I am using to mock react-native:

const MyMock = {
    MockA: {
        methodA: jest.genMockFn()
    },
    MockB: {
              


        

Answer 1

I hadn't read the error message fully. On the last line(slightly obscured) there is this:

Note: This is a precaution to guard against uninitialized mock variables. If it is ensured that the mock is required lazily, variable names prefixed with mock are permitted.

So when I changed MyMock to for instance mockMyMock, it worked.
