                                String className)

determineCoverageGoals

protected void determineCoverageGoals()

Initialize the set of known coverage goals

handleConstructorExceptions

protected void handleConstructorExceptions(AbstractTestSuiteChromosome<? extends ExecutableChromosome> suite,
                                           List<ExecutionResult> results,
                                           Set<String> calledMethods)

If there is an exception in a super-constructor, then the corresponding constructor might not be included in the execution trace

Parameters:

results -

calledMethods -

analyzeTraces

protected boolean analyzeTraces(AbstractTestSuiteChromosome<? extends ExecutableChromosome> suite,
                                List<ExecutionResult> results,
                                Set<String> calledMethods)

Iterate over all execution results and summarize statistics

Parameters:

results -

calledMethods -

Returns:

isValidPosition

protected boolean isValidPosition(ExecutionResult result,
                                  Integer position)

asSortedList

protected static <T extends Comparable<? super T>> List<T> asSortedList(Collection<T> c)

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

printStatusMessages

protected void printStatusMessages(AbstractTestSuiteChromosome<? extends ExecutableChromosome> suite,
                                   int coveredMethods,
                                   double fitness)

Some useful debug information

Parameters:

coveredMethods -

fitness -

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:
