Applied Functional Programming with Scala - Notes

1. Mastering Functions

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.

// Sequentially runs the tests, isolating the Fixture in each test.  The Fixture carries the TestKit
// so each test gets its own ActorSystem
