public class InviteServerTransactionsStateMachineTest
extends MessageFlowHarness

* The test tries to verify that Invite Server Transactions correctly change states as specified by the rfc3261. The Reference Implementation is used to send requests and a Tested Implementation ServerTransaction's states are queried and compared to those in the state machine described in section 17.2.1 of rfc3261

Method Detail

testProceedingCompletedConfirmedScenario

public void testProceedingCompletedConfirmedScenario()

Tries to steer a TI server transaction through the following scenario Proceeding-->Completed-->Confirmed-->Terminated. Apart from state transitions, we also test, retransmissions and proper hiding/passing of messages to the TU.

testCanceledInvite

public void testCanceledInvite()

JvB: tests CANCEL for an INVITE ST

testNonRFC3261CanceledInvite

public void testNonRFC3261CanceledInvite()

JvB: tests CANCEL for an INVITE ST, from an non-RFC3261 client which uses a Via branch not starting with the magic cookie

testCaseInsensitiveCanceledInvite

public void testCaseInsensitiveCanceledInvite()

JvB: tests CANCEL for an INVITE ST, in case the client changes the case of the branch id to all lowercvase (NIST used to do this)

testProceedingTerminatedScenario

public void testProceedingTerminatedScenario()

Tries to steer a TI server transaction through the following scenario Proceeding-->Terminated. Apart from state transitions, we also test, retransmissions and proper hiding/passing of messages to the TU.
