### Question:
DefaultRelationalInputGeneratorInitializer implements RelationalInputGeneratorInitializer { public ConfigurationValueRelationalInputGenerator getConfigurationValue() { return new ConfigurationValueRelationalInputGenerator(identifier, generatorList.toArray( new RelationalInputGenerator[generatorList .size()])); } DefaultRelationalInputGeneratorInitializer(
    ConfigurationRequirementRelationalInput requirementRelationalInput); @Override void initialize(ConfigurationSettingFileInput setting); @Override void initialize(ConfigurationSettingTableInput setting); ConfigurationValueRelationalInputGenerator getConfigurationValue();  }### Answer:
@Test public void testInitialization() throws AlgorithmConfigurationException, FileNotFoundException, UnsupportedEncodingException, InputGenerationException, InputIterationException { String expectedIdentifier = "some identifier"; ConfigurationRequirementRelationalInput requirement = new ConfigurationRequirementRelationalInput( expectedIdentifier, 2); String expectedFileName1 = "some file name"; String expectedFileName2 = "some other file name"; String expectedFilePath1 = new FileFixture("some file content").getTestData(expectedFileName1).getPath(); String expectedFilePath2 = new FileFixture("some other file content").getTestData(expectedFileName2).getPath(); requirement.checkAndSetSettings(new ConfigurationSettingFileInput(expectedFilePath1), new ConfigurationSettingFileInput(expectedFilePath2)); DefaultRelationalInputGeneratorInitializer initializer = new DefaultRelationalInputGeneratorInitializer(requirement); ConfigurationValueRelationalInputGenerator actualValue = initializer.getConfigurationValue(); RelationalInputParameterAlgorithm algorithm = mock(RelationalInputParameterAlgorithm.class); Set<Class<?>> interfaces = new HashSet<>(); interfaces.add(AlgorithmType.RELATIONAL_INPUT.getAlgorithmClass()); actualValue.triggerSetValue(algorithm, interfaces); ArgumentCaptor<RelationalInputGenerator> captor = ArgumentCaptor.forClass(RelationalInputGenerator.class); verify(algorithm).setRelationalInputConfigurationValue(eq(expectedIdentifier), captor.capture(), captor.capture()); List<RelationalInputGenerator> actualValueList = captor.getAllValues(); assertEquals(actualValueList.get(0).generateNewCopy().relationName(), expectedFileName1); assertEquals(actualValueList.get(1).generateNewCopy().relationName(), expectedFileName2); }
