Testfälle Meycan Switch
PreCons for each:
GIVEN XX XX is the deviceId of the target device
GIVEN YY YY is another device id, which is NOT XX XX
GIVEN 2nd CAN Debug Device on another CanBus of switch
1) A MeyPin can be triggered directly (repeat Test for all MeyPins and each CAN Bus Interface specified)
WHEN Send CAN Pkg 00 55 11 11 | XX XX 01 01 -> (MeyPin1 Should switch to on)
THEN The MeyPin 1 should trigger
THEN you receive a message 00 50 XX XX | 01 01
THEN 2nd device should receive 2 messages
* 00 50 XX XX | 01 01
* 00 55 11 11 | XX XX 01 01
1a) A MeyPin trigger is effecltess, if only set
GIVEN the above testcast
WHEN Send CAN Pkg 00 55 11 11 | XX XX 01 01
THEN Nothing changed
THEN you dont receive a message
THEN 2nd device should receive 00 55 11 11 | XX XX 01 01
WHEN Send CAN Pkg 00 55 11 11 | XX XX 01 00 -> (MeyPin1 Should switch to off)
THEN The MeyPin 1 should switch to OFF
THEN you receive a message 00 50 XX XX | 01 00
THEN 2nd device should receive 2 messages
* 00 50 XX XX | 01 00
* 00 55 11 11 | XX XX 01 00
2) A MeyPin is not triggered, if the device id dont match
WHEN Send CAN Pkg 00 55 11 11 | YY YY 01 01
THEN None of the pins of the device triggered
THEN you receive no message
THEN 2nd device should receive 1 messages
* 00 55 11 11 | XX XX 01 01
3) A MeyPin is not triggered, if the Package Type dont match
WHEN Send CAN Pkg 50 00 11 11 | YY YY 01 01
THEN None of the pins of the device triggered
THEN you receive no message
THEN 2nd device should receive 1 messages
* 50 00 11 11 | XX XX 01 01
3) A MeyPin is not triggered, if the MeyPin is above 8 (max pins)
WHEN Send CAN Pkg 00 55 11 11 | XX XX 09 01
THEN None of the pins of the device triggered
THEN you receive no message
THEN 2nd device should receive 1 messages
* 00 55 11 11 | XX XX 09 01
THEN you can execute any other testcase, as the switch didnt crash
4) All MeyPins can be activated more than 15 minutes in parallel(Activate each port for at least 15 mins)
GIVE You have a relais connected to each of the ports
WHEN Send CAN Pkg 00 55 11 11 | XX XX 01 01 -> (MeyPin1 Should switch to on)

Testfälle Meycan Switch
PreCons for each:
GIVEN XX XX is the deviceId of the target device
GIVEN YY YY is another device id, which is NOT XX XX
GIVEN 2nd CAN Debug Device on another CanBus of switch
1) A MeyPin can be triggered directly (repeat Test for all MeyPins and each CAN Bus Interface specified)
WHEN Send CAN Pkg 00 55 11 11 | XX XX 01 01 -> (MeyPin1 Should switch to on)
THEN The MeyPin 1 should trigger
THEN you receive a message 00 50 XX XX | 01 01
THEN 2nd device should receive 2 messages
* 00 50 XX XX | 01 01
* 00 55 11 11 | XX XX 01 01
1a) A MeyPin trigger is effecltess, if only set
GIVEN the above testcast
WHEN Send CAN Pkg 00 55 11 11 | XX XX 01 01
THEN Nothing changed
THEN you dont receive a message
THEN 2nd device should receive 00 55 11 11 | XX XX 01 01
WHEN Send CAN Pkg 00 55 11 11 | XX XX 01 00 -> (MeyPin1 Should switch to off)
THEN The MeyPin 1 should switch to OFF
THEN you receive a message 00 50 XX XX | 01 00
THEN 2nd device should receive 2 messages
* 00 50 XX XX | 01 00
* 00 55 11 11 | XX XX 01 00
2) A MeyPin is not triggered, if the device id dont match
WHEN Send CAN Pkg 00 55 11 11 | YY YY 01 01
THEN None of the pins of the device triggered
THEN you receive no message
THEN 2nd device should receive 1 messages
* 00 55 11 11 | XX XX 01 01
3) A MeyPin is not triggered, if the Package Type dont match
WHEN Send CAN Pkg 50 00 11 11 | YY YY 01 01
THEN None of the pins of the device triggered
THEN you receive no message
THEN 2nd device should receive 1 messages
* 50 00 11 11 | XX XX 01 01
3) A MeyPin is not triggered, if the MeyPin is above 8 (max pins)
WHEN Send CAN Pkg 00 55 11 11 | XX XX 09 01
THEN None of the pins of the device triggered
THEN you receive no message
THEN 2nd device should receive 1 messages
* 00 55 11 11 | XX XX 09 01
THEN you can execute any other testcase, as the switch didnt crash
4) All MeyPins can be activated more than 15 minutes in parallel(Activate each port for at least 15 mins)
GIVE You have a relais connected to each of the ports
WHEN Send CAN Pkg 00 55 11 11 | XX XX 01 01 -> (MeyPin1 Should switch to on)
WHEN Send CAN Pkg 00 55 11 11 | XX XX 02 01 -> (MeyPin2 Should switch to on)
