Better rake:stats Test Code Ratio Metrics

It doesn’t make much sense to me why rake:stats will only return 0.1 precision on the test code ratio. So, if you’d like a more precise metric make a change to the code in Rails:

rails/lib/code_statistics.rb
from:

    def print_code_test_stats
      code  = calculate_code
      tests = calculate_tests

      puts "  Code LOC: #{code}     Test LOC: #{tests}     Code to Test Ratio: 1:#{sprintf("%.1f", tests.to_f/code)}"
      puts ""
    end

    def print_code_test_stats
      code  = calculate_code
      tests = calculate_tests

      puts "  Code LOC: #{code}     Test LOC: #{tests}     Code to Test Ratio: 1:#{sprintf("%.3f", tests.to_f/code)}"
      puts ""
    end
