Package de.rwth.swc.coffee4j.algorithmic.sequential.manager

Class BasicSequentialCombinatorialTestManager

java.lang.Object

de.rwth.swc.coffee4j.algorithmic.sequential.manager.BasicSequentialCombinatorialTestManager

All Implemented Interfaces:

SequentialCombinatorialTestManager

public class BasicSequentialCombinatorialTestManager
extends Object
implements SequentialCombinatorialTestManager

A very basic manager for combinatorial tests. It is basic in the sense that it does not support any form of test result caching and/or parallel generation of test input groups.

Constructor Detail

BasicSequentialCombinatorialTestManager

public BasicSequentialCombinatorialTestManager(SequentialCombinatorialTestConfiguration configuration,
                                               CompleteTestModel model)

Method Detail

generateInitialTests

public List<int[]> generateInitialTests()

Generates all test input groups given by the supplied TestInputGroupGenerators. All test inputs are then returned. During the generation, the method GenerationReporter.testInputGroupGenerated(TestInputGroup, TestInputGroupGenerator) is called for each generated TestInputGroup.

Specified by:

generateInitialTests in interface SequentialCombinatorialTestManager

Returns:

all generated test inputs from all groups. They are returned in the exact order in which the TestInputGroupGenerators returned them inside TestInputGroups.

generateAdditionalTestInputsWithResult

public List<int[]> generateAdditionalTestInputsWithResult(int[] testInput,
                                                          TestResult testResult)

Returns all additional test inputs needed for all TestInputGroups managed by this manager. For each managed TestInputGroup the following flow is used: 1. Check if the test input is contained in either the initial set of generated test inputs (first iteration) or in the requested test inputs for fault characterization (in all other iterations) 1.1 If that is not the input, return an empty list of additionally needed test inputs 1.2 if that is the input, check whether fault characterization is enabled (factory is given, group has configuration, a test input in the initial set failed) 1.2.1 if FL is not enabled, the group is considered finished and will never return test inputs again 1.2.2 else, new test inputs are generated by the fault characterization algorithm provided by the factory and returned

When necessary, the method called the necessary methods on a given reporter: -GenerationReporter.faultCharacterizationStarted(TestInputGroup, FaultCharacterizationAlgorithm) -GenerationReporter.faultCharacterizationTestInputsGenerated(TestInputGroup, List) -GenerationReporter.faultCharacterizationFinished(TestInputGroup, Map, Set) -GenerationReporter.testInputGroupFinished(TestInputGroup)

Specified by:

generateAdditionalTestInputsWithResult in interface SequentialCombinatorialTestManager

Parameters:

testInput - the test inputs for which's result additional test inputs shall be generated

testResult - whether the test input was successful and if not how the failure was caused

Returns:

a combined list of test inputs generated by the fault characterization of each test input group
