busted
Elegant Lua unit testing
busted is a unit testing framework with a focus on being easy to use. Supports Lua >= 5.1, luajit >= 2.0.0, and moonscript. busted test specs read naturally without being too verbose. You can even chain asserts and negations, such as assert.is_not.equal. Nest blocks of tests with contextual descriptions using describe, and add tags to blocks so you can run arbitrary groups of tests.
