ScalaCheckFunction

trait ScalaCheckFunction extends ScalaCheckProperty

A ScalaCheckFunction adds the possibility to select various typeclass instances for a given property:

  • Arbitrary to generate values
  • Shrink to shrink counter-examples
  • Show to display arguments in case of a counter-example
  • Collector to collect values and provide a summary as string (to show frequencies for example)
