Testing
-------

Unit Tests

  The gtest framework library <https://github.com/google/googletest> is required
  in order to write and compile unit tests in libyami. To make it convenient to 
  use, we add gtest source to subdirectory `gtestsrc`. The gtest documentation 
  can be found in their source tree under `docs` (online or in the subdirectory 
  `gtestsrc`).

  To build gtest and enable the unit tests, when configuring libyami you need to
  specify:

    --enable-tests

  We highly recommend that unit tests accompany your contributed patches.  See
  "Testing" section above.  However, we do understand that not everything can
  be tested by a unit test. So use your best judgement to determine if a unit
  test is appropriate for your contribution.  The maintainer(s) reserve the
  right to refuse submission's without unit tests, when reasonable, or if a
  submission causes existing unit tests to regress.
