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
• colorblind-friendliness

• Ruby 1.8.6
• (recommended) C compiler: you can also use rcov without the rcovrt extension but rcov will be two orders of magnitude slower. The extension requires Ruby 1.8.6 or later.

De-compress the archive and enter its top directory. Then type:

($ su)
 # ruby setup.rb

This simple step installs rcov under the default location for Ruby libraries. You can also customize the installation by supplying some options to setup.rb. Try "ruby setup.rb --help".

A normal (rcovrt-enabled) install requires Ruby >= 1.8.6 and a working C toolchain; if you cannot compile Ruby extensions proceed as described below.

You might have to install a "development package" (often named ruby-dev or ruby1.8-dev), or alternatively build ruby from the sources, if the compiler cannot find the headers (ruby.h and friends).

($su )
# ruby setup.rb all --without-ext

will install rcov without building the rcovrt extension.

In the common scenario, your tests are under test/ and the target code (whose coverage you want) is in lib/. In that case, all you have to do is use rcov to run the tests (instead of testrb), and a number of XHTML files with the code coverage information will be generated, e.g.

rcov -Ilib test/*.rb

will execute all the .rb files under test/ and generate the code coverage report for the target code (i.e. for the files in lib/) under coverage/. The target code needs not be under lib/; rcov will detect is as long as it is require()d by the tests. rcov is smart enough to ignore "uninteresting" files: the tests themselves, files installed in Ruby's standard locations, etc. See rcov --help for the list of regexps rcov matches filenames against.

rcov can also be used from Rake; see readme_for_rake or the RDoc documentation for more information. The Rakefile included in rcov's sources holds a few tasks that run rcov on itself, producing a number of reports. You can try

rake rcov

preferably after a full install or

ruby setup.rb config
ruby setup.rb setup

so that the rcovrt extension can be used to speed up the process. This will generate a cross-referenced XHTML report under coverage/.

rcov can output information in several formats, and perform different kinds of analyses in addition to plain code coverage. See rcov --help for a description of the available options.
