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:

getFitness

public double getFitness(AbstractTestSuiteChromosome<? extends ExecutableChromosome> suite)

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

Specified by:

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

Parameters:

suite - a Chromosome object.

Returns:

new fitness

getMaxValue

public int getMaxValue()
