http://tir.mongrel2.org/downloads/tir-0.9-1.rockspec The above rockspec doesn't seem to install the testing.lua. Disclaimer: I know nothing about rockspecs, but tir test fails for me: /opt/local/bin/lua: tests/app_tests/angels_tests.lua:1: module 'tir/testing' not found: If it's just me then no problem, I'll go debug my environment.
