Unit Testing

First, check with the README to see what the latest approach is. As of this writing (June 2019), this works:

mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Debug -DBUILD_TESTING=ON
make
make test

The tests themselves are .cpp files in the test directory (e.g. test/accidentals.cpp). The test/CMakeLists.txt file has a list of the tests that will be built/run. Individual tests can be run directly from the build directory:

build/test/accidentals

This information appears to be outdated.

Unit tests are useful to call code in isolation during development (so you don't need to start the entire GUI to test every change), and for regression tests.

A couple of unit tests for Rosegarden have been written in src/test.

Enable WANT_TEST in ccmake and build the codebase as usual

Run 'make test'

• write tests in src/test/foo.cpp
• define an 'int test_foo(int argc, char** argv)'. This method will be called by the test driver, which will report 'Success' if the call returned '0'. If you put multiple tests in one file, this will looks something like 'return test1() + test2() + test3()', where all other tests should also return 0 on success or a positive integer on failure.
• add to src/TestFileList.txt
• Enjoy :)
