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 into a sequence diagram tool on a computer;

linking a first action of the plurality of actions with a second action of the plurality of actions using the sequence diagram tool;

generating a test sequence diagram which maintains the linking using the sequence diagram tool;

editing said first action of the plurality of actions in said test diagram, thereby causing said edits to affect a corresponding change in the second action as a result of said 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. The method of claim 1, wherein said step of inputting a plurality of actions for a hot-fire test further comprises entering said plurality of actions into a computerized database and wherein said step of linking a first action of the plurality of actions with a second action of the plurality of actions comprises linking a first computer entry corresponding to said first action and a second computer entry corresponding to said second action such that an alteration to said first or second computer entry affects a corresponding alteration in the other of said first or second computer entry.

11. The method of claim 1, wherein said step of linking a first action of the plurality of actions with a second action of the plurality of actions creates a link between said first action and said second action such that an alteration to one of said first or second action causes a corresponding alteration to the other of said first or second action.

20. The method of claim 10, wherein said step of generating a test sequence diagram which maintains the linking further comprises generating a visual representation of a test sequence, and wherein said visual representation comprises a representation of said linking.

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

inputting a plurality of valve actions for a hot-fire test into a sequence diagram tool on a computer;

linking a first action of said plurality of valve actions with a second action of said plurality of valve actions using the sequence diagram tool; and

generating a test sequence diagram which maintains the linking using the sequence diagram tool; and

editing said first action of the plurality of actions in said test diagram, thereby causing said edits to affect a corresponding change in the second action as a result of said linking.

13. A method as recited in claim 12, 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.

14. A method as recited in claim 13, 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.

15. A method as recited in claim 14, 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.

16. The method of claim 12, wherein said step of linking a first action of said plurality of valve actions with a second action of said plurality of valve actions creates a link between said first action and said second action such that an alteration to one of said first or second action causes a corresponding alteration to the other of said first or second action.

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

inputting a plurality of valve actions into a sequence diagram tool on a computer, wherein the plurality of valve actions comprise 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 using the sequence diagram tool; and

generating a test sequence diagram which maintains the delay using the sequence diagram tool; and

editing said first action of the plurality of actions in said test diagram, thereby causing said edits to affect a corresponding change in the second action as a result of said linking.

18. A method as recited in claim 17, wherein said linking further comprises:

adjusting the delay.

19. A method as recited in claim 18, wherein said generating further comprises:

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

21. The method of claim 17, wherein said step of linking the action of opening the ignition valve with the action of opening the fuel valve with a delay creates a link between the action of opening the ignition valve and the action of opening the fuel valve with a delay such that an alteration to one of said action of opening the ignition valve and said action of opening the fuel valve with a delay causes a corresponding alteration to the other of said action of opening the ignition valve and said action of opening the fuel valve with a delay.
