Coco For Linux

Coco is an open source and free command-line software implemented in Ruby and designed from the offset to be used by Ruby developers as a code coverage utility. It is easy to setup, works with Rails, it’s fully configurable, and provides console-based and simple HTML reports.

Key features include support for Ruby 1.9.2, Ruby 2.0 and Ruby 2.1, easy configuration through an YAML file, support for UTF-8 encodings, colorized console output, support for displaying names of uncovered files on console, support for generating simple HTML reports for uncovered files, support for reporting sources that don’t have tests, as well as support for rspec.

The easy way to install Coco on your GNU/Linux operating system, is to use the ‘gem install coco’ command, considering the fact that you have Ruby installed. Another easy way to install Coco is to use the ‘gem coco’ command in your Gemfile.

If for some reason you can’t install Coco using the gem command, you can always get the latest version of the project from Softpedia, where it is distributed as a tarball (TAR archive). Save the package somewhere on your computer, unpack it, and open the Terminal app.

In the terminal emulator, navigate to the location of the location of the extracted archive files using the ‘cd’ command (e.g. cd /home/softpedia/coco-0.12.0) and run the ‘rake’ command to create the gem.

After installation, you will be able to add Coco at the beginning of your tests by including the “required 'coco'” line (without double quotes) in the spec_helper.rb or test_helper.rb files of your Ruby project.

Taking a look under the hood of Coco, we can notice that it has been written entirely in the Ruby programming language. The project is fully compatible with all distributions of Linux, supporting 64-bit (x86_64) and 32-bit (x86) flavors.
