### Question:
ResponseFromHub { public String getResponseId() { return responseId; } @SuppressWarnings("unused")//Needed by JAXB private  ResponseFromHub();  ResponseFromHub(
            String responseId,
            String inResponseTo,
            String authnRequestIssuerEntityId,
            List<String> encryptedAssertions,
            Optional<String> relayState,
            URI assertionConsumerServiceUri,
            TransactionIdaStatus status); String getAuthnRequestIssuerEntityId(); String getResponseId(); String getInResponseTo(); List<String> getEncryptedAssertions(); Optional<String> getRelayState(); URI getAssertionConsumerServiceUri(); TransactionIdaStatus getStatus(); @Override String toString(); @Override boolean equals(Object o); @Override int hashCode();  }### Answer:
@Test public void getResponseId() { assertThat(responseFromHub.getResponseId()).isEqualTo(RESPONSE_ID); }
