Member Function Documentation

def Peach::MutateStrategies::ppstrategies::RandomMutationStrategy::__init__	(		self,
			args
	)

Constructor of the strategy.

Does basic initialization

Parameters:

args

Constructor arguments. No special arguments are required by this strategy

Reimplemented in Peach::MutateStrategies::ppstrategies::SingleRandomMutationStrategy, and Peach::MutateStrategies::ppstrategies::DoubleRandomMutationStrategy.

def Peach::MutateStrategies::ppstrategies::RandomMutationStrategy::_getNodeCount	(		self,
			node
	)			[private]

Get number of node children.

Return the number of DataElements that are children of node

def Peach::MutateStrategies::ppstrategies::RandomMutationStrategy::currentMutator

(

self

)

Get current mutator.

Gets current mutator

def Peach::MutateStrategies::ppstrategies::RandomMutationStrategy::getCount

(

self

)

Get number of states.

Get number of strategy states. Relevant especially for sequential based strategies.

def Peach::MutateStrategies::ppstrategies::RandomMutationStrategy::next

(

self

)

Switch to next state.

Switches strategy to next state. Relevant especially for sequential based strategies

def Peach::MutateStrategies::ppstrategies::RandomMutationStrategy::onDataModelGetValue	(		self,
			action,
			dataModel
	)

Alter data in the data model.

Called for fuzzing data in the data model

Parameters:

	action	Action we are starting
	dataModel	DataModel we are using

def Peach::MutateStrategies::ppstrategies::RandomMutationStrategy::onTestCaseFinished	(		self,
			test,
			count,
			stateEngine
	)

On TestCase Starting.

Called right at the end of iteration (test case)

Parameters:

	test	Current test being run
	count	Current test number
	stateEngine	StateEngine instance in use

def Peach::MutateStrategies::ppstrategies::RandomMutationStrategy::onTestCaseStarting	(		self,
			test,
			count,
			stateEngine
	)

On TestCase Starting.

Called right before start of iteration (test case)

Parameters:

	test	Current test being run
	count	Current test number
	stateEngine	StateEngine instance in use
