Method Detail

updateCoveredGoals

public boolean updateCoveredGoals()

Description copied from class: FitnessFunction

if the fitness function contains an archive, updates the archive and the fitness values of the population, and returns true. if the fitness function doesn't contain an archive, return false. This method has to be invoked after each generation.

Overrides:

updateCoveredGoals in class FitnessFunction<AbstractTestSuiteChromosome<? extends ExecutableChromosome>>

Returns:

runTest

public ExecutionResult runTest(TestCase test)

Execute a test case

Overrides:

runTest in class TestSuiteFitnessFunction

Parameters:

test - The test case to execute

Returns:

Result of the execution

getNumMutants

public int getNumMutants()

runTest

public ExecutionResult runTest(TestCase test,
                               Mutation mutant)

runTest

Parameters:

test - a TestCase object.

mutant - a Mutation object.

Returns:

a ExecutionResult object.

getFitness

public abstract double getFitness(AbstractTestSuiteChromosome<? extends ExecutableChromosome> individual)

Calculate and set fitness function #TODO the 'set fitness' part should be done by some abstract super class of all FitnessFunctions

Specified by:

getFitness in class FitnessFunction<AbstractTestSuiteChromosome<? extends ExecutableChromosome>>

Parameters:

individual - a Chromosome object.

Returns:

new fitness
