Method Detail

seed

java.util.Optional<java.lang.String> seed()

The seed used to generate randomized parameters.

Returns:

an optional String

falsifiedParameters

java.util.Optional<java.util.List<java.lang.Object>> falsifiedParameters()

The potentially shrunk list of parameters that falsified this property.

The parameter list returned contains the actual parameters used during the property run. If one or more parameters were changed during the run, this change is visible here.

Returns:

an optional list of parameters

status

PropertyExecutionResult.Status status()

The final status of this property

Returns:

status enum

throwable

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

Will return Optional.empty() if status is anything but FAILED. If FAILED the optional MUST contain a throwable.

countChecks

int countChecks()

The number of tries for which parameters were created and the property method run.

Returns:

an number equal to or greater than 0

countTries

int countTries()

The number of tries for which parameters were created and the property method run and which were not aborted, e.g. through a failing assumption.

Returns:

an number equal to or greater than 0

originalSample

@API(status=EXPERIMENTAL,
     since="1.3.5")
java.util.Optional<FalsifiedSample> originalSample()

Return the original falsified sample if there was one.

Returns:

an optional falsified sample

shrunkSample

@API(status=EXPERIMENTAL,
     since="1.3.5")
java.util.Optional<ShrunkFalsifiedSample> shrunkSample()

Return the shrunk falsified sample if successful shrinking took place.

Returns:

an optional falsified sample

mapTo

PropertyExecutionResult mapTo(PropertyExecutionResult.Status newStatus,
                              java.lang.Throwable throwable)

Use to change the status of a property execution result in a AroundPropertyHook.

Parameters:

newStatus - Status enum

throwable - Throwable object or null

Returns:

the changed result object

mapToSuccessful

default PropertyExecutionResult mapToSuccessful()

Use to change the status of a failed property to PropertyExecutionResult.Status.SUCCESSFUL in a AroundPropertyHook.

Returns:

the changed result object

mapToFailed

default PropertyExecutionResult mapToFailed(java.lang.Throwable throwable)

Use to change the status of a successful property execution to PropertyExecutionResult.Status.FAILED in a AroundPropertyHook.

Parameters:

throwable - Throwable object or null

Returns:

the changed result object

mapToFailed

default PropertyExecutionResult mapToFailed(java.lang.String message)

Use to change the status of a successful property execution to PropertyExecutionResult.Status.FAILED in a AroundPropertyHook.

Parameters:

message - a String that serves as message of an assertion error

Returns:

the changed result object

mapToAborted

default PropertyExecutionResult mapToAborted(java.lang.Throwable throwable)

Use to change the status of a property execution to PropertyExecutionResult.Status.ABORTED in a AroundPropertyHook.

Parameters:

throwable - Throwable object or null
