| 30 | ** UAC tests. |
| 31 | ** |
| 32 | ** This file performs various tests for UAC transactions. Each test will have |
| 33 | ** a different Via branch param so that message receiver module and |
| 34 | ** transaction user module can identify which test is being carried out. |
| 35 | ** |
| 36 | ** TEST1_BRANCH_ID |
| 37 | ** Perform basic retransmission and timeout test. Message receiver will |
| 38 | ** verify that retransmission is received at correct time. |
| 39 | ** This test verifies the following requirements: |
| 40 | ** - retransmit timer doubles for INVITE |
| 41 | ** - retransmit timer doubles and caps off for non-INVITE |
| 42 | ** - retransmit timer timer is precise |
| 43 | ** - correct timeout and retransmission count |
| 44 | ** Requirements not tested: |
| 45 | ** - retransmit timer only starts after resolving has completed. |
| 46 | ** |
| 47 | ** TEST2_BRANCH_ID |
| 48 | ** Test scenario where resolver is unable to resolve destination host. |
| 49 | ** |
| 50 | ** TEST3_BRANCH_ID |
| 51 | ** Test scenario where transaction is terminated while resolver is still |
| 52 | ** running. |
| 53 | ** |
| 54 | ** TEST4_BRANCH_ID |
| 55 | ** Test scenario where transport failed after several retransmissions. |
| 56 | ** |
| 57 | ** TEST5_BRANCH_ID |
| 58 | ** Test scenario where transaction is terminated by user after several |
| 59 | ** retransmissions. |
| 60 | ** |
| 61 | ** TEST6_BRANCH_ID |
| 62 | ** Test successfull non-INVITE transaction. |
| 63 | ** It tests the following requirements: |
| 64 | ** - transaction correctly moves to COMPLETED state. |
| 65 | ** - retransmission must cease. |
| 66 | ** - tx_data must be maintained until state is terminated. |
| 67 | ** |
| 68 | ** TEST7_BRANCH_ID |
| 69 | ** Test successfull non-INVITE transaction, with provisional response. |
| 70 | ** |
| 71 | ** TEST8_BRANCH_ID |
| 72 | ** Test failed INVITE transaction (e.g. ACK must be received) |
| 73 | ** |
| 74 | ** TEST9_BRANCH_ID |
| 75 | ** Test failed INVITE transaction with provisional response. |
