See theCompare companion object
trait Compare[A, B]

A type-class that is used to compare values in MUnit assertions.

By default, uses == and allows comparison between any two types as long they have a supertype/subtype relationship. For example:

  • Compare[T, T] OK
  • Compare[Some[Int], Option[Int]] OK, subtype
  • Compare[Option[Int], Some[Int]] OK, supertype
  • Compare[List[Int], collection.Seq[Int]] OK, subtype
  • Compare[List[Int], Vector[Int]] Error, requires upcast to Seq[Int]
