Method Summary

Modifier and Type	Method and Description
java.util.Optional<java.lang.Throwable>	falsifyingError() The error which resulted in falsifying a property.
java.util.List<java.lang.Object>	parameters() The actual parameters used when running a property method.
java.util.List<Shrinkable<java.lang.Object>>	shrinkables() The list of shrinkables that were used to generate the parameters.

Method Detail

parameters

java.util.List<java.lang.Object> parameters()

The actual parameters used when running a property method.

If parameters are muted during the run, e.g. elements have been added to a mutable collection, this method returns the muted objects.

Returns:

list of objects of same size as list returned by shrinkables().

shrinkables

java.util.List<Shrinkable<java.lang.Object>> shrinkables()

The list of shrinkables that were used to generate the parameters. The position of shrinkables corresponds to the actual parameter object in parameters().

You can create a fresh, unchanged list of parameter objects through sample.shrinkables().stream(Shrinkable::value).collect(Collectors.toList()).

Returns:

list of shrinkables of same size as list returned by parameters().

falsifyingError

java.util.Optional<java.lang.Throwable> falsifyingError()

The error which resulted in falsifying a property. If the property was falsified by return false this method returns Optional.empty().

Returns:

an optional error
