== Test Run

Given an example ruby project with a `.locat` file:

  match 'lib/**.rb' do |file, line|
    case line
    when /^\s*#/
      'Comment'
    when /^\s*$/
      'Blank'
    else
      'Code'
    end
  end

Running the locat command should produce the expected HTML file.

  LOCat.cli('--output', 'locat.html')

  File.assert.exist?('locat.html')
