Zint frontend test suite
------------------------

See <project-dir>/backend/tests/README first to build the backend test suite, as
its library <project-dir>/backend/tests/build/libtestcommon.a is used here. Then

  cd <project-dir>
  cd frontend/tests
  mkdir build
  cd build
  cmake ..
  make

If the backend test suite was made with -DZINT_SANITIZE:BOOL=1 then instead

  cd <project-dir>
  cd frontend/tests
  mkdir build
  cd build
  cmake -DZINT_SANITIZE:BOOL=1 ..
  make

-DZINT_DEBUG:BOOL=1 can also be used.

------------------------------------------------------------------------------

Only a single test is defined:

./test_args

As with the backend tests, individual test functions and single dataset items
can be run using '-f <func-name>' and '-i <index>' etc.
