rcov is a code coverage tool for Ruby. It is commonly used for viewing overall test coverage of target code. It features: - fast execution: 20-300 times faster than previous tools - multiple analysis modes: standard, bogo-profile, "intentional testing", dependency analysis... - detection of uncovered code introduced since the last run ("differential code coverage") - fairly accurate coverage information through code linkage inference using simple heuristics - cross-referenced XHTML and several kinds of text reports - support for easy automation with Rake and Rant - colorblind-friendliness
rcov can be useful for testing, optimizing and understanding your Ruby programs.
