Initial seed to use for testing.

val maxDiscardRatio: Float

The maximum ratio between discarded and passed tests allowed before ScalaCheck gives up and discards the whole property (with status Test.Exhausted). Additionally, ScalaCheck will always allow at least minSuccessfulTests * maxDiscardRatio discarded tests, so the resulting discard ratio might be higher than maxDiscardRatio.

Concrete fields

val maxRNGSpins: Int

Maximum number of spins of the RNG to perform between checks. Greater values will reduce reuse of values (with dimimishing returns) for a given number of arguments to Prop.forAll tests. Greater values will also generally lead to slower tests, so be careful.
