### Question:
ContributorProfileService { public boolean isContributorCodeTypesSupported(String contributorCodeType) { return TSC_SUPPORTED.contains(contributorCodeType); }  boolean isContributorCodeTypesSupported(String contributorCodeType); String getContributorId(String contributorCodeType, String contributorCodeValue, boolean forceCreate); String createOrUpdateProfile(String contributorCodeType, String contributorCodeValue, boolean forceUpdate); SearchResponse findByContributorCode(String contributorCode); boolean deleteByContributorCode(String code); @TransactionAttribute(TransactionAttributeType.NEVER) int fullSynContributorsAndProfiles(String contributorCodeType, Integer start, Integer size); @TransactionAttribute(TransactionAttributeType.NEVER) int createOrUpdateAllProfiles(String contributorCodeType); void contributorDeletedEventHandler(@Observes ContributorDeletedEvent event); void contributorMergedEventHandler(@Observes ContributorMergedEvent event); void contributorCodeChangedEventHandler(@Observes ContributorCodeChangedEvent event); static final String FIELD_TSC_JBOSSORG_USERNAME; static final String FIELD_TSC_GITHUB_USERNAME; static final String SEARCH_INDEX_NAME; static final String SEARCH_INDEX_TYPE; }### Answer:
@Test public void isContributorCodeTypesSupported() { ContributorProfileService tested = getTested(null); Assert.assertFalse(tested.isContributorCodeTypesSupported(null)); Assert.assertFalse(tested.isContributorCodeTypesSupported("")); Assert.assertFalse(tested.isContributorCodeTypesSupported("unknown")); Assert.assertTrue(tested.isContributorCodeTypesSupported(ContributorProfileService.FIELD_TSC_JBOSSORG_USERNAME)); }
