Checkers

object Checkers extends Checkers

Companion object that facilitates the importing of Checkers members as an alternative to mixing it in. One use case is to import Checkers members so you can use them in the Scala interpreter.

    Returns a MaxSize property check configuration parameter containing the passed value, which specifies the maximum size parameter to provide to ScalaCheck, which it will use when generating objects for which size matters (such as strings or lists).

    Note that the maximum size should be greater than or equal to the minimum size. This requirement is enforced by the PropertyCheckConfig constructor and the forAll methods of traits PropertyChecks and Checkers. In other words, it is enforced at the point both a maximum and minimum size are provided together.
