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 code:
more accurate line coverage
branch coverage
can be used as a drop-in replacement for the built-in Coverage library.
回答3:
Use Ruby's built in Coverage feature if you are wanting something very simple. It is what Simplecov uses under the hood.
