What is this?

I got tired of typing these all the time to run one test in our suite:

$ rake test TEST=test/unit/some_test.rb
$ rake test TEST=test/integration/some_integration_test.rb

Instead, I wanted to be able to do:

$ rtu s (tab complete to some_test.rb or other matching files in test/unit/)
$ rti s (tab complete to some_integration_test.rb or other matching files in test/integration/)

and have them run the same thing as the first set of commands. The following scripts let you do just that!

This guide was awesome in figuring out how to configure the filename completion: http://devmanual.gentoo.org/tasks-reference/completion/index.html

rti

#! /bin/bash

# Create this file someplace in your PATH and make sure it's executable.
# I put this in ~/bin and added ~/bin to my PATH.

rake test TEST=test/integration/$1

rtu

#! /bin/bash

# Create this file someplace in your PATH and make sure it's executable.
# I put this in ~/bin and added ~/bin to my PATH.

rake test TEST=test/unit/$1
