Double Shot #663

I'll just be over here in the corner, trying to write some code.

• Public Beta: Deployment Stacks: You now have a choice of Debian and Ruby versions on Heroku.
• Smart HTTP Transport - Interesting, setting up your own git server might get easier now.
• Smack a Ho.st - Easier testing for Rails apps with subdomains.
• Ruby's Metaprogramming Toolbox - An introduction.
• Highlight - Syntax highlighting for Rails projects via a plugin that wraps pygments.
• Stubbing and Setting Expectations on HTTP Requests Is Now Easy With WebMock - Looks like a potential alternative to fakeweb with a bit more spice.
• identity-map - Simple Identity Mapper implementation for Active Record.

Easy rcov with Test::Unit and Rails 2

Yesterday, I needed test coverage numbers for an application using Rails 2.3 and plain old Test::Unit (still my test framework of choice). This proved to be a good deal more difficult than I expected: there are so many forks of the original rcov code, and so much disparate advice on how to get it hooked up, that I spent a great deal of unprofitable time reading before I got the right combination. Hopefully this short list will save you from doing the same:

1. Install the relevance-rcov gem. This is the stable and maintained fork.
2. Install the commondream rcov_plugin. This has the best set of working rake tasks I've found.
3. Add coverage/* and test/coverage/* to your .gitignore.
4. Run rake test:coverage to generate coverage results.
5. Open /coverage/index.html in your project to view the results.

Double Shot #619

Looks like the next RailsBridge BugMash is going to focus on Rails 3, just before the beta. This could be interesting.

• Lemon - Yet another ruby unit test framework, this one focused on making sure there's a test case for every method.
• Reincarnate - How to make a ruby class inherit from itself.
• Sphinx Monitoring Plugin - The latest nice touch from the Scout guys.
• Cromwell - Wrapper for ruby signal handling to allow you to easily create unkillable scripts.
• Stencil - Free-text (ie, not assuming HTML) templating system.
• Rubinius 1.0.0-RC2 Released - Ruby in Ruby moves along.
• Firebug 1.6a1 - The next branch of Firebug (for Firefox 3.6/3.7) has gone live.
