Minitest::Cc o Minitest Code Coverage

Minitest::Cc is a plugin for Minitest that provide a very simple and minimalism measure of code coverage by your tests.

You need to keep in mind that this information is only a reference and don't represent how effective are your tests.

Add it into your Gemfile:

# Gemfile
gem 'minitest-cc'

Then you need to require it in the very top of your test helper file:

require 'minitest/cc'
Minitest::Cc.start

If you run your tests you will see something like this:

Running 24 tests in a single process (parallelization threshold is 50)
Run options: --seed 6319

# Running:

........................

# Coverage:


lines: 95%    branches: 75%     methods: 93%


Finished in 1.875197s, 12.7987 runs/s, 18.6647 assertions/s.
24 runs, 35 assertions, 0 failures, 0 errors, 0 skips

Minitest::Cc.start(:lines, :branches, :methods) # this is like look by default

• You can choose whatever you want. I think are very explicit so don't need explanation.

You can configure two aspects more:

• Mode of cc the report:

Minitest::Cc.cc_mode = :resume

• It could be :resume, the default behavior
• It could be :per_file to get a list of files and his coverage

• Files tracked:

Minitest::Cc.tracked_files = [
  './app/**/*.rb',
  './lib/**/*.rb'
]

• Path to your files that should be tested.

This configuration must be do in the helper file of your tests.
