Stuck on Learn Ruby The Hard Way #46 rake aborted

Question

I made the project skeleton as described in Learn Ruby The Hard Way #43 and created the structure stated.

The problem occurs when I run rake test and the prompt spouts out the following:

/home/username/.rbenv/versions/2.2.2/bin/ruby -I"lib:tests"  "/home/username/.rbenv/versions/2.2.2/lib/ruby/2.2.0/rake/rake_test_loader.rb" "tests/test_NAME.rb"

Command failed with status (1): [ruby -I"lib:tests"  "/home/username/.rbenv/versions/2.2.2/lib/ruby/2.2.0/rake/rake_test_loader.rb" "tests/test_NAME.rb" ]

Tasks: TOP => test
(See full trace by running task with --trace)

Can anybody tell me why the rake test gets aborted and how to possibly fix it?

Thank you.

Thank you Anthony! You are golden! Just needed to install the test-unit gem with gem install test-unit
