anchor.diff:  * Change the call to add the tests to 'add_test_with_context()'
   
   Done.
  +
  +It is good that this is a simple process, because you can change over
  +from TDD style to BDD style in small steps. You can convert one source
  +file at a time, by just following the recipe above. Everything will
  +still work as before but your tests and code will likely improve.
  +
  +And once you have changed style you can fully benefit from the
  +automatic discovery of tests as described in <<runner, Automatic Test
  +Discovery>>.

positive.code: Setup, Teardown and custom reporters
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  
  At the time of writing there is no way to use setup and teardown
  functions with the runner. If you have setup and/or teardown you need
  to go to the BDD style using 'BeforeEach()' and 'AfterEach()' as
  described in <<changing_style>> above.
  
  Neither is it possible to use custom reporters as outlined in the
  previous chapter.
  
negative.code: talk to IDE plug-ins, paint pretty printed documents or just return a boolean
  for monitoring purposes.
