I must thank the community here for helping me with a few issues along the way (mostly due to poor documentation). It uses a lot of compile time reflection to generate the mocks, which has been very interesting to learn/write (to say the least). I think it's useful enough now to release and it would be nice to perhaps receive some guidance as to where it should improve or fails spectacularly. Wikipedia: http://en.wikipedia.org/wiki/Unit_testing DUnit: https://github.com/kalekold/dunit See examples and documentation for usage. Have fun. You might want to use alternatively you could use "version(unittest)" instead of "debug" for the mocks. Don't know which is better. -- /Jacob Carlborg

Until now, my preferred tool for (large-scale) unit testing in D would be the combination of my dunit framework (of course), DMocks-revived for mocks, and the 'must' matchers of specd. How does your toolkit fit in? I looked at DMocks and Specd before i started work on DUnit to see what was out there. I'm not saying that DUnit does anything really different than those two combined but i'm trying to make it simpler to use and more intuitive. For example DMocks uses an intermediary object to handle the mocks. This is thought was a bit strange as this behaviour should be in the mock to begin with. So my first objective was to provide a way of very simply creating a mock object and to interact with that mock object directly. This also fulfilled the secondary objective of moving 'setup' code out of the unit test and making them more easy to read. Also DUnit solved the problem that Dmocks doesn't address of correctly handling Object base class methods properly. All methods can fall-through to parent implementations or be replaced at runtime. Specd is a nice approach to defining constraints but again it seems overkill for something that should be simple. I don't do anything different, i just do it in a different way. specd: 1.must.be.greater_than(0); dunit: 1.assertGreaterThan(0); The reason i've gone with just providing more specific assert methods is that i can create nice helpful error message when things go wrong. For example this line: 1.assertEquals(0); Creates this error: + | Failed asserting equal + | File: example.d | Line: 85 + | ✓ Expected int: 1 | ✗ Actual int: 2 Making debugging what went wrong loads easier.
