How can I get verbose output when running tests?

Step-by-step guide

When you run the tests via CMake (which actually runs ctest), you are only told if it passed or failed. After a failure you want to re-run the test and see all of what the test was doing.
So for example you run the tests first:

   ctest

  1. Now let's assume you see the test "t_bufr_ls" has failed. Now re-run just that test (not everything) with the verbose option:

       ctest -VV -R t_bufr_ls

  2. This -VV switch tells ctest not to suppress its output. Another method is to run all the tests with the "--output-on-failure" option of ctest:

      ctest --output-on-failure
