/**
 * 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. *
