trait Configuration extends AnyRef
Trait providing methods and classes used to configure property checks provided by the
the forAll
methods of trait GeneratorDrivenPropertyChecks
(for ScalaTest-style
property checks) and the check
methods of trait Checkers
(for ScalaCheck-style property checks).

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.

- case class MaxDiscarded(value: Int) extends PropertyCheckConfigParam with Product with Serializable
A
PropertyCheckConfigParam
that specifies the maximum number of discarded 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 throwsDiscardedEvaluationException
, which is produce bywhenever
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 withDiscardedEvaluationException
.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.- Annotations
