Brian Takita and Alex Chaffee gave a presentation at the SDForum Silicon Valley Ruby Conference over the weekend, entitled Full-stack web app testing with Selenium and Rails (slides hosted at SlideShare).

We also attended a few talks (unfortunately we couldn't attend the whole thing). A few highlights:

Mongrel HTTP handlers.

From Brian:

I'm at Ezra's Mongrel HTTP Handler's talk and it looks like a way to improve Tracker's JSON performance.

The simple "Hello World" benchmark was something like this:

• Rails: ~121 req/sec
• Mongrel: ~900 req/sec

There is an in-process mode that a mongrel HTTP handler can be run in. This handler will be run in process of your rails app. You have access to Active Record. It just avoids ActionController.

Ezra wrote a framework named Merb (Mongrel + ERB).

Also, mongrel is thread safe. Also, Ezra shared that he wants to avoid magic in Merb.

Ezra's slides are online now.

Here's what Josh wrote about Merb.

Heckle

Heckle is a framework for doing "mutation testing" (like Jester for Java). Kevin Clark demoed it and it looks like a valuable addition to any Ruby build (though probably not as a requirement for a green build -- more like part of a nightly metrics run).

Microformats

Chris Wanstrath of Err the Blog gave a talk that was ostensibly about Web Services but that actually ran a manic gamut from SOAP to Microformats to Firefox plugins to command-line blogs to mock object libraries. His speaking style is deceptively laid-back -- if you don't pay close attention, especially to code examples, you'll miss entire open-source civilizations being born and collapsing. Fortunately, I had just given a talk so my neurons were all juiced up, which meant I could just barely keep up. Bottom line for microformats: gem install mofo.
