title: Does django testing have a breakDown() similar to setUp() that is ran after all tests complete?
body: <p>I am running some tests in django but they depend on a response from an outside service. For instance,
  I might create a customer and wish to acknowledge it has been created in the outside service.</p>
  <p>Once I am done with testing I want to remove any test customers from the outside service.</p>
  <p>Ideally, there would be a method similar to <code>setUp()</code> that runs after all tests have completed.
  Does anything like this exist?</p>
