Scenario r_basic Scenario r_basic is the first scenario of an SMTP test session. This scenario tests the Receiver-SMTP Implementation Under Test (IUT) for basic mail reception and the compliance of the IUT Remote Driver (RD) to the DCA Protocol Laboratory SMTP Remote Driver Specification. If the IUT and the RD do not produce good results on the first run of this test scenario, then further testing should be abandoned until the problems are corrected. In scenario r_basic the Central Driver (CD) commands the Laboratory Driver (LD) to mail a message to the IUT. The CD then verifies the receipt of the message by commanding the RD to read the IUT's mail queue and send the results back to the CD using the RD spool command. The CD verifies that the correct command responses and mail message were received. TEST 1: BASIC MAIL RECEPTION (RECEIVER-SMTP) Does the IUT correctly receive a mail message and store it in its mail queue? ACTION: The CD establishes a connection with the IUT. The CD conducts a basic mail transaction (HELO, MAIL, RCPT, DATA, QUIT) sending a message containing a unique message identification number. The RD reads the IUT mail queue and sends back the mail message to the CD in a Test Scenario Language (TSL) data packet. VERIFICATION: The CD searches the contents of the TSL data packet for the correct command replies and message identification (id) number. SUCCESS: The correct command replies and message id are found. FAILURE: Any of the following indicates an IUT failure: Connection not made; Incorrect command replies received; RD does not correctly interpret CD commands, or acknowledge CD commands, or format IUT responses; Message id is wrong or nonexistent. Scenario s_basic Scenario s_basic tests the Sender-SMTP IUT for basic mail transmission capability. If the Sender-SMTP IUT and RD do not produce good results on the first run of this test scenario, then further testing should be abandoned until the problems are corrected. 12 March 1987 -8- Unisys Corporation TM-WD-8801/610/01 In scenario s_basic the CD commands the RD to place a mail message with a known message identification number on the IUT's queue. The mail message is addressed to the Reference Receiver SMTP at the Protocol Laboratory. The Sender-SMTP IUT should start a mail transaction and send the message. The CD confirms the receipt of the message by reading the laboratory mail queue. The CD verifies that the correct mail message was received by searching for the known message identification number. TEST 2: BASIC MAIL TRANSMISSION (SENDER-SMTP) Does the IUT Sender-SMTP correctly format and transmit a mail message? ACTION: The CD establishes a connection with the IUT. The CD commands the RD to place a mail message with a unique id number on the IUT mail queue. The Sender-SMTP IUT should find the message in the queue and start a mail transaction. The mail message is sent to the Reference Receiver-SMTP. The Reference places the message on the Lab mail queue. The CD commands the LD to spool the mail message. The LD passes the mail message, including the id number, to the CD in a TSL data packet. VERIFICATION: The CD searches for the correct command sequences and the correct message id number. SUCCESS: The correct command sequences and message id are found. FAILURE: Any of the following indicates an IUT failure: Connection not made; Command sequences are incorrect; RD does not correctly interpret CD commands, or acknowledge CD commands, or format IUT responses; Message id is wrong or nonexistent. Scenario r_helomulti Scenario r_helomulti tests the Receiver-SMTP IUT capability to correctly process multiple HELO commands after the start of a mail transaction. TEST 3: MULTIPLE HELO COMMANDS DURING TRANSACTION Does the IUT correctly process multiple HELO commands after the start of a mail transaction? ACTION: The CD establishes a connection with the IUT. Multiple HELO commands are issued, followed by a QUIT command. 12 March 1987 -9- Unisys Corporation TM-WD-8801/610/01 VERIFICATION: The CD searches for the correct command replies. SUCCESS: The CD receives a command reply of 250 for each HELO command. FAILURE: Any of the following indicates an IUT failure: Command replies of 500, 501, 504, or 421; Command replies other than those listed above; Connection not made; RD does not correctly interpret CD commands, or acknowledge CD commands, or format IUT responses. Scenario r_multircpt Scenario r_multircpt tests the Receiver-SMTP IUT capability to process multiple RCPT commands during a mail transaction. TEST 4: MULTIPLE RCPT COMMANDS DURING A TRANSACTION Does the IUT correctly process multiple recipients? ACTION: The CD establishes a connection with the IUT. The CD first sends the HELO and MAIL commands. Then the CD sends multiple RCPT commands. VERIFICATION: The CD searches for the correct command replies. The CD also checks the mail queue for multiple mail messages. All messages should be received with the correct message id number. SUCCESS: CD receives a command reply of 250 or 251, and all messages are received with the correct message id. FAILURE: Any of the following indicates an IUT failure: Command error reply of 500, 501, 503, 421 received; Command failure reply of 550, 551, 552 553 450 451, or 452 received; Connection not made; RD does not correctly interpret CD commands, or acknowledge CD commands, or format IUT responses; A message id is wrong or nonexistent. Scenario r_send Scenario r_send tests the Receiver-SMTP IUT capability to process the SEND command. The CD commands the LD to send a mail message with a known identification number to the destination IUT's terminal screen (not to a mailbox). The tester must verify the correct receipt of the message by manually checking the terminal screen. 12 March 1987 -10- Unisys Corporation TM-WD-8801/610/01 TEST 5: SEND COMMAND DURING A TRANSACTION Does the IUT correctly process the SEND command? ACTION: The CD establishes a connection with the IUT. The CD commands the LD to issue the SEND command with a known message identification number. The message is displayed on the destination terminal screen. VERIFICATION: The CD searches for the correct command reply and receives manual verification of correct message receipt at destination terminal. Also, no mail message should have been spooled onto IUT mail queue. SUCCESS: The CD receives a command reply of 250, a manual verification of message receipt, and no mail message is found on IUT mail queue. FAILURE: Any of the following indicates an IUT failure: Command failure reply of 552, 451, or 452; Command error reply of 500, 501, 502, or 421; Mail message found on IUT mail queue; Connection not made; RD does not correctly interpret CD commands, or acknowledge CD commands, or format IUT responses; Message id is wrong or nonexistent. Scenario r_sendbad Scenario r_sendbad tests the Receiver-SMTP IUT capability to process the SEND command with an undeliverable destination address. If the IUT offers SEND service, then the CD commands the LD to send a mail message to the IUT. The message will always be undeliverable since the message will be addressed to a test user who would not be logged on. Therefore, the IUT should notify the CD of an undeliverable message. TEST 6: SEND COMMAND WITH AN UNDELIVERABLE ADDRESS Does the IUT correctly process undeliverable mail using the SEND command? ACTION: The CD establishes a connection with the IUT. The CD commands the LD to send a mail message to a nonexistent user. VERIFICATION: The CD searches for the correct error reply to the RCPT command (the RCPT command is used in conjunction with the SEND command). SUCCESS: The CD receives an error reply of 550 or 421. 12 March 1987 -11- Unisys Corporation TM-WD-8801/610/01 FAILURE: Any of the following indicates an IUT failure: Command success reply of 250, or 251 received; Command error reply of 500, 501, or 503 received; Command failure reply of 551, 552, 553, 450, 451, or 452; Connection not made; RD does not correctly interpret CD commands, or acknowledge CD commands, or format IUT responses; Message id is wrong or nonexistent. Scenario r_soml Scenario r_soml tests the Receiver-SMTP IUT capability to process the SOML command. The CD commands the LD to send or mail a mail message with a known identification number to the destination IUT's terminal screen or mailbox. If the message does not get placed onto the IUT mail queue, then the tester must verify the correct receipt of the message by manually checking the terminal screen. TEST 7: SOML COMMAND DURING A TRANSACTION (RECEIVER-SMTP) Does the Receiver-SMTP IUT correctly process the SOML command? ACTION: The CD establishes a connection with the IUT. The CD commands the LD to issue the SOML command with a known message identification number. The message is either displayed on the destination terminal screen or placed onto the IUT mail queue, but not both. VERIFICATION: The CD searches for the correct command reply and, if the message was not placed onto the IUT mail queue, receives manual verification of correct message receipt at destination terminal. Also, no mail message should have been placed onto the IUT mail queue if the message was displayed at the destination terminal. SUCCESS: The CD receives a command reply of 250, a manual verification of message receipt at destination terminal, and no mail message is found on IUT mail queue; or, a 250 reply with no message received at the destination terminal, but a correct message placed onto the IUT mail queue. FAILURE: Any of the following indicates an IUT failure: Command failure reply of 552, 451, or 452; Command error reply of 500, 501, 502, or 421; Connection not made; RD does not correctly interpret CD commands, or acknowledge CD commands, or format IUT responses; Message id is wrong or nonexistent. 12 March 1987 -12- Unisys Corporation TM-WD-8801/610/01 Scenario s_soml Scenario s_soml tests the Server-SMTP IUT capability to process the SOML command. The CD commands the RD to queue a mail message with a known identification number. The IUT should find the message in the queue and send or mail the message to the destination terminal screen or mailbox. If the message does not get placed onto the laboratory mail queue, then the lab tester must verify the correct receipt of the message by manually checking the destination terminal screen. The destination is the tsl mailbox or terminal. TEST 8: SOML COMMAND DURING A TRANSACTION (SENDER-SMTP) Does the Sender-SMTP IUT correctly process the SOML command? ACTION: The CD establishes a connection with the RD. The CD commands the RD to queue a mail message with a known identification number. The IUT should find the message in the queue and send or mail the message to the laboratory destination terminal screen or mailbox. The destination is the tsl mailbox or terminal. If the message does not get placed onto the laboratory mail queue, then the lab tester must verify the correct receipt of the message by manually checking the destination terminal screen. VERIFICATION: The CD searches for the correct message identification number in the laboratory mail queue. If the message was not placed onto the mail queue, then manual verification of correct message receipt at destination terminal is performed by lab tester. Also, no mail message should have been placed onto the mail queue if the message was displayed at the destination terminal. SUCCESS: The CD finds the correct message identification number in the mail queue and no message appears at the destination terminal. Or, the message appears at the destination terminal and no message is found in the mail queue. FAILURE: Any of the following indicates an IUT failure: Message does not appear in either the destination mail queue or at the destination terminal, or appears at both; Connection not made; RD does not correctly interpret CD commands, or acknowledge CD commands, or format IUT responses; Message id is wrong or nonexistent. 12 March 1987 -13- Unisys Corporation TM-WD-8801/610/01 Scenario r_saml Scenario r_saml tests the Receiver-SMTP IUT capability to process the SAML command.
