A function that is used in the same module it was declared cannot be spied mocked, unless it's consistently as a method of some object, which is cumbersome and incompatible with ES modules:

Jest hoists all of the calls to jest.mock on the top of the scope (it's mentioned in few places in the documentation). And even though it's also mentioned that the variables prefixed with mock will also be hoisted apparently they go below the jest.mock calls causing this error to happen.

I can advice you to use the auto-mocking feature of jest

Based on the excellent answers I am attempting to implement JestJS on a similar function.

Question

The problem seams to be how I am inserting the mocked response data in jest.mock(). Below have I described and included all the files I have used.

Your function getStatusCode checks the response and returns -1 or 0.

So you can't expect it to have a property status

You can check if it is toBeGreaterThanOrEqual to zero

Since in your implementation you're calling axios.request with an object that has baseURL, it doesn't matches your assertion.

So you can either assert that it has to be called with an object that has baseURL
