Input / expected output tests

[MaxwellBo]

Scala Center Advisory Board Accessible Scala proposal provided some examples for testing - many more are needed.

Current tests

Example tests:

case class Person(name: String, address: Address, age: Int)
// case class Person containing name String, address Address and age Int
// --summary --prefer=symbols: case class Person with name, address and age
// --summary --prefer=types:   case class Person with String, Address and Int

trait Monad[F[_]] extends Applicative[F] {
    // five methods defined here...
}
// trait Monad with higher type F extending applicative of F with five declarations
// trait Monad higher F

val a = 5
// val a with value 5 
// val a

type ErrorsOr[A] = ValidatedNel[String, A]
// type alias ErrorsOr type A equal to ValidatedNel of String and type A
// alias ErrorsOr A
