provide to ScalaCheck, which it will use when generating objects for which size matters (such as
strings or lists).

Abstract class defining a family of configuration parameters for property checks.
Abstract class defining a family of configuration parameters for property checks.
The subclasses of this abstract class are used to pass configuration information to
the forAll methods of traits PropertyChecks (for ScalaTest-style
property checks) and Checkers(for ScalaCheck-style property checks).
A PropertyCheckConfigParam that (with minSize) 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).
A PropertyCheckConfigParam that (with minSize) 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 size range is added to minSize in order to calculate the maximum size passed to ScalaCheck. Using a range allows compile-time checking of a non-negative number being specified.

to use when evaluating a property.

property evaluations allowed during property evaluation.
A PropertyCheckConfigParam that specifies the maximum number of discarded
property evaluations allowed during property evaluation.
In GeneratorDrivenPropertyChecks, a property evaluation is discarded if it throws
DiscardedEvaluationException, which is produce by whenever clause that
evaluates to false. For example, consider this ScalaTest property check:
// forAll defined in GeneratorDrivenPropertyChecks
forAll { (n: Int) =>
whenever (n > 0) {
doubleIt(n) should equal (n * 2)
}
}
In the above code, whenever a non-positive n is passed, the property function will complete abruptly
with DiscardedEvaluationException.
Similarly, in Checkers, a property evaluation is discarded if the expression to the left
of ScalaCheck's ==> operator is false. Here's an example:
// forAll defined in Checkers
forAll { (n: Int) =>
(n > 0) ==> doubleIt(n) == (n * 2)
}
For either kind of property check, MaxDiscarded indicates the maximum number of discarded
evaluations that will be allowed. As soon as one past this number of evaluations indicates it needs to be discarded,
the property check will fail.

A PropertyCheckConfigParam that 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.

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