rcov is a code coverage tool for Ruby. It is commonly used for viewing overall
test unit coverage of target code.  It features fast execution (20-300 times
faster than previous tools), multiple analysis modes, XHTML and several kinds
of text reports, easy automation with Rake via a RcovTask, fairly accurate
coverage information through code linkage inference using simple heuristics,
colorblind-friendliness...
