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

To make, first make libzint with ZINT_TEST defined:

  cd <project-dir>
  mkdir build
  cd build
  cmake -DZINT_TEST=ON ..
  make

Then make the tests:

  cd <project-dir>
  cd backend/tests
  mkdir build
  cd build
  cmake -DZINT_TEST=ON ..
  make

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

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

To run all tests (within <project-dir>/backend/tests/build):

  ctest

To run individual tests, eg:

  ./test_common
  ./test_vector

To run a single test function within an individual test, use '-f <func-name>':

  ./test_common -f utf8_to_unicode
  ./test_dotcode -f input

To run a single dataset item in a single test function, use '-i <index>':

  ./test_dotcode -f input -i 2

To show debug info (if any), use '-d <flag>':

  ./test_dotcode -f input -i 2 -d 1

(for other flags see <project-dir>/backend/tests/testcommon.h)

To generate test data, use '-g':

  ./test_dotcode -f encode -g

To run a test against BWIPP (if any), use '-d 128':

  ./test_composite -d 128

(see also <project-dir>/backend/tests/tools/run_bwipp_tests.sh)

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

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

  cd <project-dir>
  cd build
  cmake -DZINT_SANITIZE=ON ..
  make && sudo make install

Then set for tests and make:

  cd <project-dir>
  cd backend/tests/build
  cmake -DZINT_SANITIZE=ON ..
  make

Similarly to make with gcc debug:

  cd <project-dir>
  cd build
  cmake -DZINT_DEBUG=ON ..
  make && sudo make install

  cd <project-dir>
  cd backend/tests/build
  cmake -DZINT_DEBUG=ON ..
  make

To undo sanitize/debug, remake each after setting:

  cmake -DZINT_SANITIZE=OFF ..
  cmake -DZINT_DEBUG=OFF ..

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

  cmake -DZINT_TEST=OFF ..

(The tests will now fail to link.)
