### Question:
DefaultProviderDataAccessor implements ProviderDataAccessor { @Override public void deleteProjects(Collection<ProviderProject> providerProjects) { providerProjects.forEach(project -> providerProjectRepository.deleteByHref(project.getHref())); } @Autowired  DefaultProviderDataAccessor(ProviderProjectRepository providerProjectRepository, ProviderUserProjectRelationRepository providerUserProjectRelationRepository, ProviderUserRepository providerUserRepository,
        ConfigurationAccessor configurationAccessor); @Override @Transactional(readOnly = true, isolation = Isolation.READ_COMMITTED) List<ProviderProject> getProjectsByProviderConfigName(String providerConfigName); @Override @Transactional(readOnly = true, isolation = Isolation.READ_COMMITTED) List<ProviderProject> getProjectsByProviderConfigId(Long providerConfigId); @Override void deleteProjects(Collection<ProviderProject> providerProjects); @Override @Transactional(readOnly = true, isolation = Isolation.READ_COMMITTED) Set<String> getEmailAddressesForProjectHref(String projectHref); @Override @Transactional(readOnly = true, isolation = Isolation.READ_COMMITTED) List<ProviderUserModel> getUsersByProviderConfigId(Long providerConfigId); @Override List<ProviderUserModel> getUsersByProviderConfigName(String providerConfigName); @Override void updateProjectAndUserData(Long providerConfigId, Map<ProviderProject, Set<String>> projectToUserData, Set<String> additionalRelevantUsers); static final int MAX_DESCRIPTION_LENGTH; static final int MAX_PROJECT_NAME_LENGTH; }### Answer:
@Test public void deleteProjectsTest() { ProviderProject providerProject = new ProviderProject(name, description, href, projectOwnerEmail); ProviderProjectRepository providerProjectRepository = Mockito.mock(ProviderProjectRepository.class); DefaultProviderDataAccessor providerDataAccessor = new DefaultProviderDataAccessor(providerProjectRepository, null, null, null); providerDataAccessor.deleteProjects(List.of(providerProject)); Mockito.verify(providerProjectRepository).deleteByHref(Mockito.any()); }
