6. Copyright © 2004, GemStone Systems Inc. All Rights Reserved. Machine Reservation System GemStone has a number of machines –Shared among developers and testers Want to keep machines as active as possible –Run tests on weekends and off hours

7. Copyright © 2004, GemStone Systems Inc. All Rights Reserved. Machine Reservation System Current system doesn’t scale –An engineer manually edits text file to make reservation –A tester has to check file before running tests or using machine –Allows two people to think they have the machine reserved –Hinders automated testing execution

8. Copyright © 2004, GemStone Systems Inc. All Rights Reserved. Machine Reservation System We’d like a new system –Reservation files readable by humans and machines –Java API that can be invoked by our testing framework Before a test is run, it can check to see if someone else has the machine reserved
