The sources in this directory are unit test cases. Boost includes a unit testing framework, and since Bitcoin Core already uses Boost, it makes sense to simply use this framework rather than require developers to configure some other framework (we want as few impediments to creating unit tests as possible).
The build system is set up to compile an executable called test_verium
that runs all of the unit tests. The main source file is called
setup_common.cpp.
Unit tests will be automatically compiled if dependencies were met in ./configure
and tests weren't explicitly disabled.
After configuring, they can be run with make check.
To run the veriumd tests manually, launch src/test/test_verium. To recompile
after a test file was modified, run make and then run the test again. If you
modify a non-test file, use make -C src/test to recompile only what's needed
to run the veriumd tests.
To add more veriumd tests, add BOOST_AUTO_TEST_CASE functions to the existing
.cpp files in the test/ directory or add new .cpp files that
implement new BOOST_AUTO_TEST_SUITE sections.
To run the verium-qt tests manually, launch src/qt/test/test_verium-qt
To add more verium-qt tests, add them to the src/qt/test/ directory and
the src/qt/test/test_main.cpp file.
test_verium has some built-in command-line arguments; for example, to run just the getarg_tests verbosely:
test_verium --log_level=all --run_test=getarg_tests
... or to run just the doubledash test:
test_verium --run_test=getarg_tests/doubledash
Run test_verium --help for the full list.
To add a new unit test file to our test suite you need
to add the file to src/Makefile.test.include. The pattern is to create
one test file for each class or source file for which you want to create
unit tests. The file naming convention is <source_filename>_tests.cpp
and such files should wrap their tests in a test suite
called <source_filename>_tests. For an example of this pattern,
see uint256_tests.cpp.
To write to logs from unit tests you need to use specific message methods
provided by Boost. The simplest is BOOST_TEST_MESSAGE.
For debugging you can launch the test_verium executable with gdbor lldb and
start debugging, just like you would with veriumd:
gdb src/test/test_verium
