node-nock-example

All examples are for nock using mocha.

Using isDone() and cleanAll() in afterEach()

Include the following to ensure nock interceptors don't affect other tests (and make debugging hard):

afterEach(function() {
  ...
  if(!nock.isDone()) {
    this.test.error(new Error('Not all nock interceptors were used!'));
    nock.cleanAll();
  }
  ...
});

See the difference in action. The bug is with the GET / five times test; it was only consuming one of the nock interceptors.
