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

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

    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.
