Unit tests will be automatically compiled if dependencies were met in ./configure
and tests weren't explicitly disabled.
After configuring, they can be run with make check.
To run the hthd tests manually, launch src/test/test_hth.
To add more hthd tests, add BOOST_AUTO_TEST_CASE functions to the existing
.cpp files in the test/ directory or add new .cpp files that
implement new BOOST_AUTO_TEST_SUITE sections.
To run the hth-qt tests manually, launch src/qt/test/test_hth-qt
To add more hth-qt tests, add them to the src/qt/test/ directory and
the src/qt/test/test_main.cpp file.
