Compiling/running unit tests
Unit tests will be automatically compiled if dependencies were met in
and tests weren't explicitly disabled.
After configuring, they can be run with
To run the litecoind tests manually, launch
src/test/test_litecoin. 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 litecoind tests.
To add more litecoind 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 litecoin-qt tests manually, launch
To add more litecoin-qt tests, add them to the
src/qt/test/ directory and
Running individual tests
test_litecoin has some built-in command-line arguments; for example, to run just the getarg_tests verbosely:
test_litecoin --log_level=all --run_test=getarg_tests
... or to run just the doubledash test:
test_litecoin --help for the full list.
Note on adding test cases
The sources in this directory are unit test cases. Boost includes a unit testing framework, and since litecoin 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 setup to compile an executable called "test_litecoin" that runs all of the unit tests. The main source file is called test_bitcoin.cpp, which simply includes other files that contain the actual unit tests (outside of a couple required preprocessor directives). 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 examples of this pattern, examine uint160_tests.cpp and uint256_tests.cpp.
Add the source files to /src/Makefile.test.include to add them to the build.
