Running ScalaTest BDD Tests from Eclipse

Stephen Haberman - 10 Sep 2009

At Bizo, we're using Scala for a few things here and there. While investigating testing approaches for Scala, I came across ScalaTest and its Behavior Driven Development (BDD) spec approach.

While its a small thing, I really like the sentence-based it "should do this and that" aspect of the spec approach. You get great readability compared to traditional "testDoThisAndThat" method names.

However, a large downside to the spec approach is that spec tests cannot, on their own, be easily, one-keyboard-shortcut run from within Eclipse. The built-in Eclipse JUnit test runner does not understand the describe/it-based test structure.

To solve this, I wrote a class that can be used with JUnit's "RunWith" annotation to bridge the gap between JUnit and ScalaTest. Its not perfect, but you get back the one-shortcut/greenbar runner in Eclipse. So I can definitely see it being handy if we decide to do any spec-based testing here at Bizo.
