Testing in Scala using a Java tool
My first post on Graceless Failures, a blog about adventures on the path to learning Scala:
Scala, like a lot of other languages these days, ships with a unit testing framework - SUnit - built in. Many other Scala specific “testing” frameworks have sprung up in recent times that contain similar or vastly different feature sets to the traditional xUnit tools. These include Reductio, ScalaCheck, Specs, ScalaTest, and SUnit (built into the Scala distribution).
And as Scala is “just Java” you can also use Java frameworks such as JUnit and TestNG. Having only used Reductio, I can’t vouch for any others, though ScalaTest is getting good airplay on Artima and Specs seems to have the Scala BDD mindshare.
These tools can be loosely categorised as traditional unit testing tools, ala xUnit, or automated specification testing tools, ala QuickCheck. Reductio and ScalaCheck are incarnations of automated specification testing, while Specs, ScalaTest and SUnit are more your traditional xUnit frameworks.
However, I’m not to write about any of these frameworks, instead, I’m going to write about Instinct, a Java BDD framework that I’ve been developing for around 18 months, and for which I’ve recently started to add specific support for Scala into the codebase. Good fodder for blog posts!
