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> 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!
