/** @file
  This is a sample to demonstrates the use of GoogleTest that supports host
  execution environments for test case that generates an exception.  For some
  host-based environments, this is a fatal condition that terminates the unit
  tests and no additional test cases are executed. On other environments, this
  condition may be report a unit test failure and continue with additional unit
  tests.
