Integrating Ruby testing in Intellij and TeamCity...made easy

One of the greatest things about scripting languages is that they can work entirely through the command line and require very little in the way of infrastructure.

For example, in my environment at work, our development environment is Java, and the tools are very Jetbrain-centric. They use Intellij for their and IDE and (more important for me) use TeamCity for continuous integration. This has two implications for me:

1. JetBrains has a Ruby plugin for Intellij which works really well, so I can use the same dev environment as our developers, even though I'm working in Ruby. It has code highlighting and code intelligence, and generally works well. I'm also playing with RubyMine, a Jetbrains all-Ruby IDE. It is based on Intellij so it has a great editor, but also supports Rake and has a nifty GUI test runner. Right now it's in "free preview mode", I'm told when it releases it will be $99, which seems pretty reasonable.
2. One requirement I had when I started working for McAfee is that our component-level tests integrate into our TeamCity environment, so that test runs could be scheduled to be kicked off and so that test results would be easily viewable by anyone on the team at the location they are already going to. This was easy, because TeamCity has a "command line" option for it's build runner. That means anything that can be kicked off through the command line can be scheduled to run. Of course, this includes RSpec-enabled Ruby scripts. Since RSpec includes an option to output to HTML, and since TeamCity has a way of pointing to build "artifacts" to view from their website, I just set up my configuration so that the script outputs to an HTML file, and then pointed to that HTML file as my build artifact. In this way, I can run Ruby tests and produce an HTML report in the TeamCity environment.
