Can anyone help me find a code coverage tool in ruby? What I want is: given a set of tests that I run, what lines of my code and what routines are covered. And also a list of uncovered routines and tests. I couldn’t find an open source one out there… – > **[Salesforce: The Customer Company](https://www.salesforce.com)** > > Personalize every experience along the customer journey with the Customer 360.

It’s slow as buggery, and isn’t perfect, but it exists and is released under Ruby’s licence. - Matt ---

I haven’t tried it myself, only Ruby Performance Validator, which is excellent. – stefan – For rails performance tuning, see: [http://railsexpress.de/blog](http://railsexpress.de/blog) Subscription: [railsexpress.de](http://railsexpress.de/blog/xml/rss20/feed.xml) ---
