= Cobra Koans = Cobra Koans are a series of focused exercises centered around learning language features by correcting code whose assertions are failing. As Laura @ DorkByte.com says: "Koans uses test driven development (TDD) or the notion of red, green, refactor. With the koans, run the tests and see it fail (red), make the test pass (green), then see if there’s any way you could improve upon it (refactor)."
