Recently I wanted to add a very simple sanity check to our sites’ build. Typically the Integration/Selenium RC tests would handle this sort of thing, but I wanted something light enough to go in continuous integration build so we would be protected from simple dll version mishaps, configuration errors, container issues, whatever. There’s probably plenty of ways to do this, and if any of you know of a better way, please let me know. In order to do it, I modified the Cassini source to run as more of a daemon, I created a simple rakefile to launch it and I use curl to verify a test url. For my test Url I simply made a Diagnostics Controller with an Ok action that returns a ContentResponse with “OK”. Pretty simple. If you need something like this, give it a shot and let me know what you think.
