LuaUnit

LuaUnit is a popular unit-testing framework for Lua, with an interface typical of xUnit libraries (Python unittest, Junit, NUnit, ...). It supports several output formats (Text, TAP, JUnit, etc.) that can be used directly or work with continuous integration platforms (Jenkins, Maven, etc.). LuaUnit may be installed as a rock or directly added to your project. For simplicity, LuaUnit is contained into a single file and has no external dependency. LuaUnit may also be used as an assertion library, to validate assertions inside a running program. In addition, it provides a pretty stringifier that converts any type into a nicely formatted string (including complex nested or recursive tables).
