-Now, in order to test this method without actually hitting the API (and thus creating slow and fragile tests), we can use the `jest.mock(...)` function to automatically mock the axios module.

-Once we mock the module we can spy on the `.get` method and provide a `mockImplementation` that returns the data we want our test to assert against. In effect, we are saying that we want axios.get('/users.json') to return a fake response.
