doMockIf is not a function

I’m trying to write an utility function that will mock the response of the profile view and the auth refresh of my API user.

I followed the docs for version 3.0.0, which is installed

npm ls | grep jest-fetch-mock
+-- jest-fetch-mock@3.0.0

When I run my tests, I get

    TypeError: fetch.doMockIf is not a function

      1 | export function mockLoggedOut() {
    > 2 |   fetch.doMockIf('api/profile/').mockResponse('UNAUTHORIZED', { status: 401})
        |         ^
      3 |   fetch.doMockIf('api/auth/refresh/').mockResponse('UNAUTHORIZED', { status: 401})
      4 | }
      5 | 

      at mockLoggedOut (src/test-utils/auth.test.tsx:2:9)
      at Object.<anonymous> (src/store/auth/actions.test.tsx:62:5)

fetch seems to be properly mocked, since doing

  ● Auth actions › checkAuth checks auth when logged out

    function mockConstructor(_a, _b) {
            return fn.apply(this, arguments);
          }

      1 | export function mockLoggedOut() {
    > 2 |   throw Error(fetch)
        |         ^
      3 |   fetch.doMockIf('api/profile/').mockResponse('UNAUTHORIZED', { status: 401})
      4 |   fetch.doMockIf('api/auth/refresh/').mockResponse('UNAUTHORIZED', { status: 401})
      5 | }

      at mockLoggedOut (src/test-utils/auth.test.tsx:2:9)
      at Object.<anonymous> (src/store/auth/actions.test.tsx:62:5)

Shows that fetch is a mock (at least it looks like)

On the other hand, doMock is working

  ● Auth actions › checkAuth checks auth when logged out

    TypeError: fetch.doMockIf is not a function

      1 | export function mockLoggedOut() {
      2 |   fetch.doMock('api/profile/').mockResponse('UNAUTHORIZED', { status: 401})
    > 3 |   fetch.doMockIf('api/auth/refresh/').mockResponse('UNAUTHORIZED', { status: 401})
        |         ^
      4 | }
      5 | 

      at mockLoggedOut (src/test-utils/auth.test.tsx:3:9)
      at Object.<anonymous> (src/store/auth/actions.test.tsx:62:5)

So, either I didn’t understand the docs, either it is not clear, either doMockIf is not working

fetch.doMockIf(/api\/(profile|auth/refresh)\//).mockResponse(req => {
   if (req.url.includes("profile")) {
      return {
       status: 401,
       body: "UNAUTHORIZED"
      }
   } else if (req.url.includes("auth")) {
      return {
          status: 403
          body: "FORBIDDEN"
       }
   }
})

Yes, it does. Thank you
