tested 0.9.4

Unit test runner with structured JSON output of results and resource usage.


To use this package, put the following dependency into your project's dependencies section:

dub.json
dub.sdl

tested

This is a simple unit test runner with the ability to measure resource usage of each test. It can produce structured test result and resource data especially suitable for automated tests and performance/resource monitoring.

To use it, simply disable D's built-in unit test runner and call runUnitTests. Your main() should just return zero or be declared as void and do nothing else:

version (unittest) {
	shared static this()
	{
		// disable built-in unit test runner
		import core.runtime;
		Runtime.moduleUnitTester = () => true;
	}

	void main()
	{
		enforce(runUnitTests!app(new JsonTestResultWriter("results.json")), "Unit tests failed.");
	}
}

Alternatively, the latest version of DUB will automatically generate the necessary code by simply running "dub test" on your project. The package description just needs to have a dependency to "tested".

Example output

Running the included example with dub --build=unittest will produce output similar to this:

$ dub --build=unittest

===========================
2 of 4 tests have passed.

FINAL RESULT: FAILED
core.exception.AssertError@source\app.d(20): Unit tests failed.

It will also generate a results.json file with detailed data, similar to this (shortened):
