GivenWhenThen

Trait that contains methods named given, when, then, and and, which take a string message and implicit Informer, and forward the message to the informer.

Here's an example:

package org.scalatest.examples.flatspec.info

import collection.mutable
import org.scalatest._

class SetSpec extends FlatSpec with GivenWhenThen {

  "A mutable Set" should "allow an element to be added" in {
    Given("an empty mutable Set")
    val set = mutable.Set.empty[String]

    When("an element is added")
    set += "clarity"

    Then("the Set should have size 1")
    assert(set.size === 1)

    And("the Set should contain the added element")
    assert(set.contains("clarity"))

    info("That's all folks!")
  }
}

If you run this SetSpec from the interpreter, you will see the following output:

scala> new SetSpec execute
A mutable Set
- should allow an element to be added
  + Given an empty mutable Set
  + When an element is added
  + Then the Set should have size 1
  + And the Set should contain the added element
  + That's all folks!

Note: The lower case forms of given, when, then and and were deprecated in ScalaTest because using then as an identifier was deprecated in Scala 2.10.
