Method Detail

startClassification

Optional<int[]> startClassification(Map<int[],Throwable> errorConstraintExceptionCausingTestInputs,
                                    List<int[]> exceptionInducingCombinationsToClassify,
                                    Set<int[]> possiblyFailureInducingCombinations)

initializes the strategy.

Parameters:

errorConstraintExceptionCausingTestInputs - all test inputs that result in an ErrorConstraintException

exceptionInducingCombinationsToClassify - all exception-inducing combinations that are found during generation

possiblyFailureInducingCombinations - all possibly failure-inducing combinations that are found during generation

Returns:

all classified exception-inducing combinations. If a combination cannot be classified, it is classified as ErrorConstraintException.

generateNextTestInputForClassification

Optional<int[]> generateNextTestInputForClassification(int[] testInput,
                                                       TestResult result)

Parameters:

testInput - last executed test input

result - result of last executed test input

Returns:

next test input to execute that is needed for classification

getClassifiedExceptionInducingCombinations

Map<int[],Class<? extends Throwable>> getClassifiedExceptionInducingCombinations()

Returns:

returns all classified exception-inducing combinations. ErrorConstraintException indicates that no classification is possible for the related combination
