Feature-level behavior testing tools for Java/Scala

Question

Is there a Java or Scala equivalent to Cucumber/SpecFlow? One possibility is using Cucumber with JRuby; any others?

Perhaps http://stackoverflow.com/questions/1068785/which-bdd-framework-for-java-do-you-use might be helpful. — Mark, Jun 08 '10 at 20:14
Have you looked at the frameworks available? Just for Scala, ScalaTest has BDD support, and Specs was designed with BDD in mind. Then there's a multitude of testing frameworks for Java. Perhaps if you could explain your requirements a bit better, it would be easier to answer this question. — Daniel C. Sobral, Jun 08 '10 at 22:02

Take a look at ScalaTest with Feature Spec. Sample feature spec from the ScalaTest website:

import org.scalatest.FeatureSpec
import org.scalatest.GivenWhenThen
import scala.collection.mutable.Stack

class ExampleSpec extends FeatureSpec with GivenWhenThen {

  feature("The user can pop an element off the top of the stack") {

    info("As a programmer")
    info("I want to be able to pop items off the stack")
    info("So that I can get them in last-in-first-out order")

    scenario("pop is invoked on a non-empty stack") {

      given("a non-empty stack")
      val stack = new Stack[Int]
      stack.push(1)
      stack.push(2)
      val oldSize = stack.size

      when("when pop is invoked on the stack")
      val result = stack.pop()

      then("the most recently pushed element should be returned")
      assert(result === 2)

      and("the stack should have one less item than before")
      assert(stack.size === oldSize - 1)
    }

    scenario("pop is invoked on an empty stack") {

      given("an empty stack")
      val emptyStack = new Stack[String]

      when("when pop is invoked on the stack")
      then("NoSuchElementException should be thrown")
      intercept[NoSuchElementException] {
        emptyStack.pop()
      }

      and("the stack should still be empty")
      assert(emptyStack.isEmpty)
    }
  }
}

specs provides Literate Specifications with "forms" to develop Fit-like specifications. You can find a post explaining the rationale of it here, and some examples of what can be done with it.

Note however that the library is still in alpha mode as I plan to give it more attention once Scala 2.8.0 has settled.

Now you can use Cucumber and define your steps in Java or pure Scala.

Here you have a short and easy tutorial on how to use it in Scala with SBT: http://func.io/post/36452127031/pure-scala-bdd-made-easy-with-sbt-and-cucumber.

JBehave works just fine with Scala. For an example, in this article, http://jnb.ociweb.com/jnb/jnbJun2010.html there is a link to a zip file that contains a sample application using JBehave implemented completely in Scala.

Look at Fitness, if you want to separate test code from acceptance text. Otherwise, both Specs and ScalaTest support BDD-style (Specs was written to be BDD-style), and lots of other Java frameworks support it was well.

JBehave was rewritten after Cucumber was released, so that we could also use plain text. Gherkin wasn't out when we wrote it, so it doesn't parse exactly the same - uses tokens instead of regexp - but it'll do the same job.
