GivenWhenThen

trait GivenWhenThen extends AnyRef

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> org.scalatest.run(new SetSpec)
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!
