Abstract

A method of generating a test sequence diagram includes: linking a first action of the plurality of actions with a second action of the plurality of actions and generating a test sequence diagram which maintains the linking.

Claims

1. A method of generating a test sequence diagram comprising:

inputting a plurality of actions for a hot-fire test;

linking a first action of the plurality of actions with a second action of the plurality of actions; and

generating a test sequence diagram which maintains the linking.

2. A method as recited in claim 1, wherein inputting a plurality of actions for the hot-fire test further comprises:

inputting a first valve actuation as the first action.

3. A method as recited in claim 2, wherein inputting a plurality of actions for the hot-fire test further comprises:

inputting a second valve actuation as the second action.

4. A method as recited in claim 3, wherein linking the first action of the plurality of actions with the second action of the plurality of actions further comprises:

linking the first action with the second action with a delay.

5. A method as recited in claim 1, wherein inputting a plurality of actions for the hot-fire test further comprises:

inputting an event as the first action.

6. A method as recited in claim 5, wherein linking the first action of the plurality of actions with the second action of the plurality of actions further comprises:

linking activation of a first valve in response to the event.

7. A method as recited in claim 6, wherein linking the first action of the plurality of actions with the second action of the plurality of actions further comprises:

closing the first valve.

8. A method as recited in claim 6, wherein inputting a plurality of actions for the hot-fire test further comprises:

opening the first valve.

9. A method as recited in claim 6, wherein linking the first action of the plurality of actions with the second action of the plurality of actions further comprises:

linking the event to a time period.

10. A method of generating a test sequence diagram comprising:

inputting a plurality of valve actions for a hot-fire test;

linking a first action of said plurality of valve actions with a second action of said plurality of valve actions; and

generating a test sequence diagram which maintains the linking.

11. A method as recited in claim 10, wherein inputting the plurality of valve actions for the hot-fire test further comprises:

inputting a first valve actuation as a first valve action of the plurality of valve actions.

12. A method as recited in claim 11, wherein inputting the plurality of valve actions for the hot-fire test further comprises:

inputting a second valve action as a second valve action of the plurality of valve actions.

13. A method as recited in claim 12, wherein linking the first action of said plurality of valve actions with the second action of said plurality of valve actions further comprises:

linking the first action with the second action with a delay.

14. A method of generating a test sequence diagram for a hot-fire test comprising:

inputting a plurality of valve actions comprising opening an oxygen valve, opening an ignition valve, and opening a fuel valve;

linking the action of opening the ignition valve with the action of opening the fuel valve with a delay; and

generating a test sequence diagram which maintains the delay.

15. A method as recited in claim 14, wherein said linking further comprises:

adjusting the delay.

16. A method as recited in claim 15, wherein said generating further comprises:

generating the test sequence diagram which maintains the linking in response to the adjusting.
