Method Detail

withTransformation

@API(status=EXPERIMENTAL,
     since="1.7.2")
ChainArbitrary<T> withTransformation(int weight,
                                                                                   Transformation<T> transformation)

Allow an additional Transformation on the generated chain.

Parameters:

weight - Determines the relative probability of a transformer to be chosen.

transformation - The provider to add.

Returns:

new instance of arbitrary

withTransformation

@API(status=EXPERIMENTAL,
     since="1.7.0")
default ChainArbitrary<T> withTransformation(Transformation<T> transformation)

Allow an additional Transformation with a default weight of 1.

Parameters:

transformation - The provider to add.

Returns:

new instance of arbitrary

withMaxTransformations

ChainArbitrary<T> withMaxTransformations(int maxTransformations)

Set the intended number of transformations of generated chains.

Setting maxTransformations to -1 creates a potentially infinite chain. Such a chain will only end when a Transformer.endOfChain() is applied.

Returns:

new instance of arbitrary

infinite

default ChainArbitrary<T> infinite()

Create a potentially infinite chain. Such a chain will only end when a Transformer.endOfChain() is applied.

Returns:

new instance of arbitrary

improveShrinkingWith

ChainArbitrary<T> improveShrinkingWith(java.util.function.Supplier<ChangeDetector<T>> detectorSupplier)

Set supplier for the type specific ChangeDetector which can make shrinking of chains more effective.

Parameters:

detectorSupplier - A function to create a new ChangeDetector instance.

Returns:

new instance of arbitrary
