Unit Test is a modern C++ unit testing framework. It compiles multiple test suites into a single executable which can then be used to run unit tests. It uses several advanced features from C++11 including lambdas and initializer lists to improve the readability and reduce boiler plate code and macro usage.

Firstly the build tool teapot needs to be installed (which requires Ruby):

$ gem install teapot

To run unit tests:

$ teapot Test/UnitTest

Typically, you'd create a directory called test and then, per component, create a file called Test.Component.cpp, e.g. test/Test.UnitTest.cpp. In this file, simply follow this template:

namespace UnitTest
{
	UnitTest::Suite StatisticsTestSuite {
		"UnitTest::Statistics",

		// Repeat this block as many times as required for various collections of unit tests.
		{"Basic pass and fail",
			[](UnitTest::Examiner & examiner) {
				UnitTest::Statistics statistics;
		
				statistics.pass_test();
				statistics.fail_test();
		
				examiner.expect(statistics.failed()).to(be_true);
			}
		},
	};
}

Perhaps a canonical example would be to look at existing projects that use unit-test, including unit-test itself.

To migrate away from the Test.*.cpp prefix use the following shell:

for f in test/**/*.cpp; do echo mv "$f" "${f#Test.}"; done

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request
