de.rwth.swc.coffee4j.algorithmic.interleaving.feedback.DefaultFeedbackCheckingStrategy

All Implemented Interfaces:

FeedbackCheckingStrategy

public class DefaultFeedbackCheckingStrategy
extends Object
implements FeedbackCheckingStrategy

Default Feedback Checking Strategy introduced in "An interleaving approach to combinatorial testing and failure-inducing interaction identification". A pre-defined number of checks are generated that are most-dissimilar to each other to increase the probability that a combination is classified correctly as failure-inducing.

Method Detail

defaultCheckingStrategy

public static FeedbackCheckingStrategyFactory defaultCheckingStrategy()

Returns:

returns a factory for creating a DefaultFeedbackCheckingStrategy.

startFeedbackChecking

public Optional<int[]> startFeedbackChecking(int[] candidate,
                                             int[] processedTestInput)

Specified by:

startFeedbackChecking in interface FeedbackCheckingStrategy

Parameters:

candidate - possibly exception/failure-inducing combination to check

processedTestInput - test input that contains possibly exception/failure-inducing combination

Returns:

first test input used for checking possibly exception/failure-inducing combination (if present, otherwise empty Optional)

toString

public String toString()

Overrides:

toString in class Object

generateNextTestInputForChecking

public Optional<int[]> generateNextTestInputForChecking(int[] testInput,
                                                        TestResult testResult)

Specified by:

generateNextTestInputForChecking in interface FeedbackCheckingStrategy

Parameters:

testInput - previously executed test input

testResult - result of previously executed test input

Returns:

next test input that is most dissimilar from previously generated tests in checking phase. Empty optional, if maximal number of feedback checks is reached or previously executed test input passed which means that combination is not failure-inducing.
