Alternative parallel test runner for Ruby with (partial) compatibility with RSpec, Test::Unit and Minitest test suites.
The aim is to allow running unmodified test suites, but this doesn't always work.
$ gem install ruptr
$ cd project-root-directory
$ ruptr
See ruptr --help for options. Options --no-capture-output and --monkey-patch may help some
test suites to run correctly. Use options -I to add include paths and -r to require extra
libraries if needed.
