/*****************************************************************************
**
** UAC tests.
**
** This file performs various tests for UAC transactions. Each test will have
** a different Via branch param so that message receiver module and
** transaction user module can identify which test is being carried out.
**
** TEST1_BRANCH_ID
** Perform basic retransmission and timeout test. Message receiver will
** verify that retransmission is received at correct time.
** This test verifies the following requirements:
** - retransmit timer doubles for INVITE
** - retransmit timer doubles and caps off for non-INVITE
** - retransmit timer timer is precise
** - correct timeout and retransmission count
** Requirements not tested:
** - retransmit timer only starts after resolving has completed.
**
** TEST2_BRANCH_ID
** Test scenario where resolver is unable to resolve destination host.
**
** TEST3_BRANCH_ID
** Test scenario where transaction is terminated while resolver is still
** running.
**
** TEST4_BRANCH_ID
** Test scenario where transport failed after several retransmissions.
**
** TEST5_BRANCH_ID
** Test scenario where transaction is terminated by user after several
** retransmissions.
**
** TEST6_BRANCH_ID
** Test successfull non-INVITE transaction.
** It tests the following requirements:
** - transaction correctly moves to COMPLETED state.
** - retransmission must cease.
** - tx_data must be maintained until state is terminated.
**
** TEST7_BRANCH_ID
** Test successfull non-INVITE transaction, with provisional response.
**
** TEST8_BRANCH_ID
** Test failed INVITE transaction (e.g. ACK must be received)
**
** TEST9_BRANCH_ID
** Test failed INVITE transaction with provisional response.
