### Question:
DeploymentVerifier { RemoteRepository[] mergeRepositories(final RemoteRepository[] r1, final RemoteRepository[] r2) { Set<RemoteRepository> remoteRepositories = new HashSet<>(); Collections.addAll(remoteRepositories, r1); Collections.addAll(remoteRepositories, r2); return remoteRepositories.toArray(new RemoteRepository[0]); } DeploymentVerifier(final Configuration config, final DiscoveryManagement discoveryManagement); void verifyDeploymentRequest(final DeployRequest request); void verifyOperationalString(final OperationalString opString, final RemoteRepository[] repositories); void verifyOperationalStringService(final ServiceElement service,
                                               final Resolver resolver,
                                               final RemoteRepository[] repositories);  }### Answer:
@Test public void testMergeRepositories() throws Exception { RemoteRepository[] r1 = new RemoteRepository[]{createRR("http: createRR("http: RemoteRepository[] r2 = new RemoteRepository[]{createRR("http: createRR("http: RemoteRepository[] repositories = deploymentVerifier.mergeRepositories(r1, r2); Assert.assertTrue(repositories.length==3); }
