Files

The test setup is the “lib” folder containing one file that defines the class, the test folders and test / sub_test, with “sub_test” containing the only “test_example_lib.rb” and a Rakefile like this:

require 'rcov / rcovtask'

task: default => [: rcov]

desc "RCov"
Rcov :: RcovTask.new do | t |
    t.test_files = FileList ['test / ** / test _ *. rb']
end

Result

#rake
