Ruby test coverage tool
问题 I need a tool which measures test coverage under Ruby. I tried rcov, but couldn't install it under Windows, Cygwin, or Ubuntu. Which programs (not necessarily free) calculate the branch and/or line coverage of tests in Ruby and work with Ruby on Rails? 回答1: Simplecov. Rcov doesn't work so well under Ruby 1.9.*, but simplecov does. 回答2: You also have deep-cover which aims to be more complete than the mentioned examples. From the Readme: Deep Cover aims to be the best coverage tool for Ruby
