Zint backend test suite
|
|
-----------------------
|
|
|
|
In order to build the zint test suite, zint has to be compiled with the
|
|
ZINT_TEST option enabled:
|
|
|
|
cd <project-dir>
|
|
mkdir build
|
|
cd build
|
|
cmake -DZINT_TEST=ON ..
|
|
cmake --build .
|
|
|
|
When using generators that support multiple build configurations, such as
|
|
Visual C++ Project Files (the default generator on win32), the configuration
|
|
can be provided via --config:
|
|
|
|
cd <project-dir>
|
|
mkdir build
|
|
cd build
|
|
cmake -DZINT_TEST=ON -DCMAKE_BUILD_TYPE=Debug ..
|
|
cmake --build . --config Debug
|
|
|
|
Note specifying a matching CMAKE_BUILD_TYPE is required to set the test PATH
|
|
environment for Windows.
|
|
|
|
------------------------------------------------------------------------------
|
|
|
|
In order to run the test suite, the path of the zint library may need to be
|
|
communicated to the runtime linker. On UNIX-like systems, this is done by
|
|
exporting LD_LIBRARY_PATH to the path containing the zint library, which is
|
|
<build-dir>/backend:
|
|
|
|
cd <project-dir>
|
|
cd build
|
|
export LD_LIBRARY_PATH=$(pwd)/backend
|
|
|
|
Setting LD_LIBRARY_PATH is not required if the zint library to be tested is
|
|
installed into a system library path ( /usr/lib for example ) prior to running
|
|
the tests, or if the tests are not run individually.
|
|
|
|
(On Windows, the PATH may need to be set to include the DLL location.)
|
|
|
|
------------------------------------------------------------------------------
|
|
|
|
To run all tests (within <build-dir>):
|
|
|
|
ctest
|
|
|
|
When using a generator that does support multiple build configurations, the
|
|
configuration that was used to build the project has to be explicitly provided
|
|
to ctest, even if it was the default one:
|
|
|
|
ctest -C Debug
|
|
|
|
For various useful options, e.g. matching (-R) and excluding (-E) tests, see
|
|
https://cmake.org/cmake/help/latest/manual/ctest.1.html#options
|
|
|
|
Tests can also be run individually, eg:
|
|
|
|
backend/tests/test_common
|
|
backend/tests/test_vector
|
|
|
|
To run a single test function within an individual test, use '-f <func-name>':
|
|
|
|
backend/tests/test_common -f utf8_to_unicode
|
|
backend/tests/test_dotcode -f input
|
|
|
|
To run a single dataset item in a single test function, use '-i <index>':
|
|
|
|
backend/tests/test_dotcode -f input -i 2
|
|
|
|
To run a range of dataset items in a single test function, use '-i <start>-<end>':
|
|
|
|
backend/tests/test_dotcode -f input -i 2-5
|
|
|
|
To exclude a single dataset item in a single test function, use '-x <index>':
|
|
|
|
backend/tests/test_dotcode -f input -x 4
|
|
|
|
This can also take a range, '-x <start>-<end>':
|
|
|
|
backend/tests/test_dotcode -f input -x 4-6
|
|
|
|
Exclude can be used multiple times (unlike '-i'):
|
|
|
|
backend/tests/test_dotcode -f input -x 4 -x 6-8
|
|
|
|
The include and exclude options can be used together:
|
|
|
|
backend/tests/test_dotcode -f input -i 2-7 -x 4 -x 6
|
|
|
|
To show debug info (if any), use '-d <flag>':
|
|
|
|
backend/tests/test_dotcode -f input -i 2 -d 1
|
|
|
|
E.g. to print which dataset items are being run, use '-d 16':
|
|
|
|
backend/tests/test_dotcode -f input -d 16 -i 2
|
|
|
|
(for other flags see <project-dir>/backend/tests/testcommon.h)
|
|
|
|
To run a test against BWIPP (if any), use '-d 128':
|
|
|
|
backend/tests/test_composite -d 128
|
|
|
|
(see also <project-dir>/backend/tests/tools/run_bwipp_tests.sh)
|
|
|
|
To run a test against ZXing-C++ (if any), use '-d 512':
|
|
|
|
backend/tests/test_rss -d 512
|
|
|
|
(see also <project-dir>/backend/tests/tools/run_zxingcpp_tests.sh)
|
|
|
|
To generate test data, use '-g':
|
|
|
|
backend/tests/test_dotcode -f encode -g
|
|
|
|
------------------------------------------------------------------------------
|
|
|
|
If the zint library was built with static linkage support, i.e. ZINT_STATIC
|
|
is ON, an additional test executable, which uses the zint-static library, will
|
|
be built. The static variant of each test shares the test name, but has a
|
|
"-static" suffix. For example,
|
|
|
|
backend/tests/test_dotcode
|
|
|
|
would run the dotcode test that uses the shared zint library, while
|
|
|
|
backend/tests/test_dotcode-static
|
|
|
|
runs the same test built against the zint-static library.
|
|
|
|
------------------------------------------------------------------------------
|
|
|
|
To make with gcc sanitize, first set for libzint and make:
|
|
|
|
cd <project-dir>
|
|
cd build
|
|
cmake -DZINT_SANITIZE=ON ..
|
|
make && sudo make install
|
|
|
|
Similarly to make with gcc debug:
|
|
|
|
cd <project-dir>
|
|
cd build
|
|
cmake -DZINT_DEBUG=ON ..
|
|
make && sudo make install
|
|
|
|
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.)
