### Question:
SCRAMSHA1Mechanism extends ScramMechanism { public SCRAMSHA1Mechanism() { super(SHA_1_SCRAM_HMAC); } SCRAMSHA1Mechanism(); @Override int getPriority(); static final String NAME; }### Answer:
@Test public void testScramSha1Mechanism() throws NotConnectedException, SmackException, InterruptedException { final DummyConnection con = new DummyConnection(); SCRAMSHA1Mechanism mech = new SCRAMSHA1Mechanism() { @Override public String getRandomAscii() { this.connection = con; return "fyko+d2lbbFgONRv9qkxdawL"; } }; mech.authenticate(USERNAME, "unusedFoo", JidTestUtil.DOMAIN_BARE_JID_1, PASSWORD, null, null); AuthMechanism authMechanism = con.getSentPacket(); assertEquals(SCRAMSHA1Mechanism.NAME, authMechanism.getMechanism()); assertEquals(CLIENT_FIRST_MESSAGE, saslLayerString(authMechanism.getAuthenticationText())); mech.challengeReceived(Base64.encode(SERVER_FIRST_MESSAGE), false); Response response = con.getSentPacket(); assertEquals(CLIENT_FINAL_MESSAGE, saslLayerString(response.getAuthenticationText())); mech.challengeReceived(Base64.encode(SERVER_FINAL_MESSAGE), true); mech.checkIfSuccessfulOrThrow(); }
