Zint backend test suite
-----------------------

To make, first make libzint with ZINT_TEST defined:

  cd <project-dir>
  mkdir build
  cd build
  cmake -DZINT_TEST:BOOL:1 ..
  make

Then make the tests:

  cd <project-dir>
  cd backend/tests
  mkdir build
  cd build
  cmake -DZINT_TEST:BOOL:1 ..
  make

(ZINT_TEST is needed to export INTERNAL functions for use and testing.)

To run all tests:

  make test

To run individual tests, eg:

  ./test_common
  ./test_vector

To make with gcc sanitize, first set for libzint and make:

  cd <project-dir>
  cd build
  cmake -DZINT_SANITIZE:BOOL=1 ..
  make && sudo make install

Then set for tests and make:

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

Similarly to make with gcc debug:

  cd <project-dir>
  cd build
  cmake -DZINT_DEBUG:BOOL=1 ..
  make && sudo make install

  cd <project-dir>
  cd backend/tests/build
  cmake -DZINT_DEBUG:BOOL=1 ..
  make

To undo sanitize/debug, remake each after setting:

  cmake -DZINT_SANITIZE:BOOL=0 ..
  cmake -DZINT_DEBUG:BOOL=0 ..

To get a clean libzint, set the above and also:

  cmake -DZINT_TEST:BOOL=0 ..

(The tests will now fail to link.)
