Explanation of output
What you can see is that two files have been tested; index.coffee and tools.coffee. The number of lines contained in the file and the percentage of those line that was covered is printed at the top and at the bottom of the report.
The main body of the report is all the lines NOT covered by tests (marked in read), and five lines of context before and after each uncovered line. The line numbers are printed along with the code itself.
