Is there a quick and easy way to test a gem which is already installed locally? Like:
gem test gem_name_to_test
rubygems docs says one can put gem: --run-tests in ~/.gemrc file to run unit tests when a gem is installed. I could not make it work though and that is not exactly what I need.
There is “gem test” command, which may or may not be what you are looking for. It run tests agains the package and sends them to test.rubygems.org.
