  -Unlike the `always_expect()` instruction, `expect()` sets up an
  -expectation of a single call and specifying `will_return()` sets the
  -single return value for just that call.  It acts like a record and
  -playback model.  Successive expectations map out the return sequence
  -that will be given back once the test proper starts.

   We'll add this test to the suite and run it...

  -------------------------
  
  We recommend the BDD notation to discover tests, and you indicate
  which context the test we want to run is in. In this example it is
  `Cgreen` so the test should be refered to as `Cgreen:this_test_should_fail`.
  
  If you don't use the BDD notation there is actually a context anyway,
  it is called `default`.

negative.code: 
  === Selecting Tests To Run
  
  You can name a single test to be run by giving it as the last argument on the command line.
  The name should be in the format `<SUT>:<test>`.
  If not obvious you can get that name by using the `--verbose` command option which will show you all tests discovered and both there C/C++ and Cgreen names.
  Copying the Cgreen name from that output is an easy way to run only that particular test.
  When a single test is named it is run using `run_single_test()`.
  As described in <<tdd_with_cgreen>> this means that it is __not__ protected by `fork()`-ing it to run in its own process.
  
  The `cgreen-runner` supports selecting tests with limited pattern matching.
  Using an asterisk as a simple 'match many' symbol you can say things like
  
  --------------------
  $ cgreen-runner <library> Cgreen:*
