For testing headcount. Project description is here

1. Put your code in a directory named headcount, at the same level as this repo. In other words, if you did an ls, you should see directories for both headcount and heacount_test_harness.
2. Run bundle install (if it doesn't know what bundle is, then run gem install bundler)
3. Run rake for the complete set of default tests (this must pass in order to get a 3 on functional requirements)

You can use mrspec directly, it is recommended that you also use bundler when running.

# run all tests
$ bundle exec mrspec

# run a test tagged with "current"
$ bundle exec mrspec -t current

# run until the first failure, then stop
$ bundle exec mrspec --fail-fast
