  44   // 1. It verifies that an ad-hoc assertion can be executed even if
  45   //    no test is defined.
  46   // 2. It verifies that a failed ad-hoc assertion causes the test
  47   //    program to fail.

  49   //    assertion is executed before RUN_ALL_TESTS() is called, even
  50   //    though --gtest_output=xml is specified.  This makes sure the
