| 30 | ** UAS 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 | ** Test that non-INVITE transaction returns 2xx response to the correct |
| 38 | ** transport and correctly terminates the transaction. |
| 39 | ** This also checks that transaction is destroyed immediately after |
| 40 | ** it sends final response when reliable transport is used. |
| 41 | ** |
| 42 | ** TEST2_BRANCH_ID |
| 43 | ** As above, for non-2xx final response. |
| 44 | ** |
| 45 | ** TEST3_BRANCH_ID |
| 46 | ** Transaction correctly progressing to PROCEEDING state when provisional |
| 47 | ** response is sent. |
| 48 | ** |
| 49 | ** TEST4_BRANCH_ID |
| 50 | ** Transaction retransmits last response (if any) without notifying |
| 51 | ** transaction user upon receiving request retransmissions on TRYING |
| 52 | ** state |
| 53 | ** |
| 54 | ** TEST5_BRANCH_ID |
| 55 | ** As above, in PROCEEDING state. |
| 56 | ** |
| 57 | ** TEST6_BRANCH_ID |
| 58 | ** As above, in COMPLETED state, with first sending provisional response. |
| 59 | ** (Only applicable for non-reliable transports). |
| 60 | ** |
| 61 | ** TEST7_BRANCH_ID |
| 62 | ** INVITE transaction MUST retransmit non-2xx final response. |
| 63 | ** |
| 64 | ** TEST8_BRANCH_ID |
| 65 | ** As above, for INVITE's 2xx final response (this is PJSIP specific). |
| 66 | ** |
| 67 | ** TEST9_BRANCH_ID |
| 68 | ** INVITE transaction MUST cease retransmission of final response when |
| 69 | ** ACK is received. (Note: PJSIP also retransmit 2xx final response |
| 70 | ** until it's terminated by user). |
| 71 | ** Transaction also MUST terminate in T4 seconds. |
| 72 | ** (Only applicable for non-reliable transports). |
| 73 | ** |
| 74 | ** TEST11_BRANCH_ID |
| 75 | ** Test scenario where transport fails before response is sent (i.e. |
| 76 | ** in TRYING state). |
| 77 | ** |
| 78 | ** TEST12_BRANCH_ID |
| 79 | ** As above, after provisional response is sent but before final |
| 80 | ** response is sent (i.e. in PROCEEDING state). |
| 81 | ** |
| 82 | ** TEST13_BRANCH_ID |
| 83 | ** As above, for INVITE, after final response has been sent but before |
| 84 | ** ACK is received (i.e. in CONNECTED state). |
| 85 | ** |
| 86 | ** TEST14_BRANCH_ID |
| 87 | ** When UAS failed to deliver the response with the selected transport, |
| 88 | ** it should try contacting the client with other transport or begin |
| 89 | ** RFC 3263 server resolution procedure. |
| 90 | ** This should be tested on: |
| 91 | ** a. TRYING state (when delivering first response). |
| 92 | ** b. PROCEEDING state (when failed to retransmit last response |
| 93 | ** upon receiving request retransmission). |
| 94 | ** c. COMPLETED state. |
