Replace the global XMLHttpRequest only for one request

[maksugr]

Do we can replace the global XMLHttpRequest only for one request? Right now, if you make .setup() all others XMLHttpRequest, that doesn't have mocks, doesn't work.

No, the current implementation requires you to call .teardown() when you want to stop mocking requests. And I think this is the optimal behaviour (because who's to say it shouldn't be two requests or three requests?).

Instead, you should call .teardown(). e.g.

mock.get('/first/request', (req, res) => {
  mock.teardown();
  return res;
});

Alternatively, you could try proxying unmocked requests to the real XHR e.g (albeit untested) https://github.com/jameslnewell/xhr-mock#proxying-requests
