My Lib PLoop <https://github.com/kurapica/PLoop> should be complex enough for testing, it's pure Lua. Download it to the LUA_PATH, run the PLoop\UnitTest\Run.lua， if meet some error with os(for pure lua, I use io.popen to check the file system in the lib, it'd works fine with windows and centos, I don't check other system), you can use the code in UnitTest <https://github.com/kurapica/PLoop/blob/master/Docs/015.unittest.md> for a test. -- Sent from: http://lua.2524044.n2.nabble.com/Lua-l-f2524044.html
