Run iOS unit tests (in a Xcode workspace) when a file changes and *only* those tests related to the changed file. Also trims otest output and colors test results.

Instructions

Enable ‘Run’ in the ‘Build’ section of your test bundle’s scheme. (See http://www.raingrove.com/2012/03/28/running-ocunit-and-specta-tests-from-command-line.html)

Install the Kicker tool and the dependencies

$ gem install kicker open4 colored xcodebuild-rb

Install the .kick example file and the otest wrapper

$ curl https://raw.github.com/gist/3011214/8f660de3ef091770290660680e7c195052b3b0e0/kick.rb > .kick
$ curl https://raw.github.com/gist/3011214/b1dd39b5509a87e16c691177926eced004fa2d14/run-tests.rb > run-tests
$ chmod +x run-tests

Update the files for your application’s requirements

$ edit .kick
$ edit run-tests

Finally, start Kicker

$ kicker -c

And an example of the output:
