Interface TestFitnessFactory<T extends TestFitnessFunction>

All Known Implementing Classes:

AbstractFitnessFactory, AllDefsCoverageFactory, AmbiguityCoverageFactory, BranchCoverageFactory, CBranchFitnessFactory, DefUseCoverageFactory, ExceptionCoverageFactory, IBranchFitnessFactory, InputCoverageFactory, LineCoverageFactory, MethodCoverageFactory, MethodNoExceptionCoverageFactory, MethodTraceCoverageFactory, MutationFactory, OnlyBranchCoverageFactory, OnlyMutationFactory, OutputCoverageFactory, RhoCoverageFactory, StatementCoverageFactory, TestSuiteFitnessFunc_to_TestFitnessFactory_Adapter, TryCatchCoverageFactory

public interface TestFitnessFactory<T extends TestFitnessFunction>

A TestFitnessFactory produces a List of goals (of type TestFitnessFunction). Each goal can be given a TestSuite and the goals determines if it is covered by the TestSuite. The difference to TestSuiteFitness functions is, that a goal is either covered or not. (i.e. the search landscape generated by goals is a plateau) GetFitness() allows the TestSuiteMinimizer to work with less assumptions about the used TestFitnessFactory. (I.e. it allows the creation of an adapter, which converts a TestSuiteFitnessFunction into a TestFitnessFactory)

Method Detail

getCoverageGoals

List<T> getCoverageGoals()

Generate a list of goals to cover

Returns:

a List object.

getFitness

double getFitness(TestSuiteChromosome suite)

Gets the fitness for suite if the goals from this TestFitnessFactory are applied. Note that some parts of TestSuiteMinimizer assume, that a smaller Fitness (e.g. 0.1) is better than a larger fitness (e.g. 2.0)

Parameters:

suite - a TestSuiteChromosome object.

Returns:

a double.
