### Type Members

1. #### class ConfiguredPropertyCheck extends AnyRef

   Performs a configured property checks by applying property check functions passed to its `apply` methods to arguments supplied by implicitly passed generators, modifying the values in the `PropertyGenConfig` object passed implicitly to its `apply` methods with parameter values passed to its constructor.

2. #### 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.

3. #### case class MaxSize (value: Int) extends PropertyCheckConfigParam with Product with Serializable

   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).

4. #### case class MinSize (value: Int) extends PropertyCheckConfigParam with Product with Serializable

   A `PropertyCheckConfigParam` that specifies the minimum size parameter to provide to ScalaCheck, which it will use when generating objects for which size matters (such as strings or lists).

5. #### case class MinSuccessful (value: Int) extends PropertyCheckConfigParam with Product with Serializable

   A `PropertyCheckConfigParam` that specifies the minimum number of successful property evaluations required for the property to pass.

6. #### case class PropertyCheckConfig (minSuccessful: Int, maxDiscarded: Int, minSize: Int, maxSize: Int, workers: Int) extends Product with Serializable

   Configuration object for property checks.

7. #### class PropertyCheckConfigParam extends AnyRef

   Abstract class defining a family of configuration parameters for property checks.

8. #### case class Workers (value: Int) extends PropertyCheckConfigParam with Product with Serializable

   A `PropertyCheckConfigParam` that specifies the number of worker threads to use when evaluating a property.

    Performs a property check by applying the specified property check function to arguments supplied by implicitly passed generators, modifying the values in the implicitly passed `PropertyGenConfig` object with explicitly passed parameter values.

    Performs a property check by applying the specified property check function to arguments supplied by implicitly passed generators, modifying the values in the implicitly passed `PropertyGenConfig` object with explicitly passed parameter values.

    This method creates a `ConfiguredPropertyCheck` object that has six overloaded apply methods that take a function. Thus it is used with functions of all six arities. Here are some examples:

        forAll (minSize(1), maxSize(10)) { (a: String) =>
          a.length should equal ((a).length)
        }

        forAll (minSize(1), maxSize(10)) { (a: String, b: String) =>
          a.length + b.length should equal ((a + b).length)
        }

        forAll (minSize(1), maxSize(10)) { (a: String, b: String, c: String) =>
          a.length + b.length + c.length should equal ((a + b + c).length)
        }

        forAll (minSize(1), maxSize(10)) { (a: String, b: String, c: String, d: String) =>
          a.length + b.length + c.length + d.length should equal ((a + b + c + d).length)
        }

        forAll (minSize(1), maxSize(10)) { (a: String, b: String, c: String, d: String, e: String) =>
          a.length + b.length + c.length + d.length + e.length should equal ((a + b + c + d + e).length)
        }

        forAll (minSize(1), maxSize(10)) { (a: String, b: String, c: String, d: String, e: String, f: String) =>
          a.length + b.length + c.length + d.length + e.length + f.length should equal ((a + b + c + d + e + f).length)
        }

    configParams

      a variable length list of `PropertyCheckConfigParam` objects that should override corresponding values in the `PropertyCheckConfig` implicitly passed to the `apply` methods of the `ConfiguredPropertyCheck` object returned by this method.

    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.

52. #### def whenever (condition: Boolean)(fun: ⇒ Unit): Unit

    Evaluates the passed code block if the passed boolean condition is true, else throws `DiscardedEvaluationException`.

    Evaluates the passed code block if the passed boolean condition is true, else throws `DiscardedEvaluationException`.

    The `whenever` method can be used inside property check functions to discard invocations of the function with data for which it is known the property would fail. For example, given the following `Fraction` class:

        class Fraction(n: Int, d: Int) {

          require(d != 0)
          require(d != Integer.MIN_VALUE)
          require(n != Integer.MIN_VALUE)

          val numer = if (d < 0) -1 * n else n
          val denom = d.abs

          override def toString = numer + " / " + denom
        }

        import org.scalatest.prop.TableDrivenPropertyChecks._

        val fractions =
          Table(
            ("n", "d"),
            (  1,   2),
            ( -1,   2),
            (  1,  -2),
            ( -1,  -2),
            (  3,   1),
            ( -3,   1),
            ( -3,   0),
            (  3,  -1),
            (  3,  Integer.MIN_VALUE),
            (Integer.MIN_VALUE, 3),
            ( -3,  -1)
          )

    Imagine you wanted to check a property against this class with data that includes some value that are rejected by the constructor, such as a denominator of zero, which should result in an `IllegalArgumentException`. You could use `whenever` to discard any rows in the `fraction` that represent illegal arguments, like this:

        import org.scalatest.matchers.ShouldMatchers._

        forAll (fractions) { (n: Int, d: Int) =>

          whenever (d != 0 && d != Integer.MIN_VALUE
              && n != Integer.MIN_VALUE) {

            val f = new Fraction(n, d)

            if (n < 0 && d < 0 || n > 0 && d > 0)
              f.numer should be > 0
            else if (n != 0)
              f.numer should be < 0
            else
              f.numer should be === 0

            f.denom should be > 0
          }
        }

    In this example, rows 6, 8, and 9 have values that would cause a false to be passed to `whenever`. (For example, in row 6, `d` is 0, which means `d` `!=` `0` will be false.) For those rows, `whenever` will throw `DiscardedEvaluationException`, which will cause the `forAll` method to discard that row.

    condition

      the boolean condition that determines whether `whenever` will evaluate the `fun` function (`condition` is true) or throws `DiscardedEvaluationException` (`condition` is false)

    fun

      the function to evaluate if the specified `condition` is true
