I recently integrated Warden into a web service I’ve been building with Sinatra. Unfortunately doing so completely broke some of my tests. I spent a while trying to figure out how to stub out the Warden object before I discovered that Warden already provides support for testing. Awesome. While I could load my config.ru in the test, there are other things in there that I’d rather not deal with while testing. I came up with the following approach, which lets me more or less test the web service in isolation.
