Indeterminate Heuristics
First Impression: Scala Goodies
by Dale Asberry

Summary
I'm test-infected and that's why one of my first exciting Scala discoveries was ScalaTest

Actually, the first big thing I noticed about Scala was the crispness I could write my code. Put it together with the ScalaTest framework and you get the following highly-readable and obvious test snippet (excerpted from ScalaTest Testing with Mock Objects: Using Borachio):

val mockCollaborator = mock[Collaborator]

mockCollaborator expects 'documentAdded withArgs ("Document")
mockCollaborator expects 'documentChanged withArgs ("Document") repeated 3 times

classUnderTest.addDocument("Document", new Array[Byte](0))
classUnderTest.addDocument("Document", new Array[Byte](0))
classUnderTest.addDocument("Document", new Array[Byte](0))
classUnderTest.addDocument("Document", new Array[Byte](0))

Clean.
