(Okay, you have to be in computer development to really get this one. But it's good. - Vikar)
A developer/tester convention was being held.
On the train to the convention, there were a bunch of developer majors and a bunch of tester majors. Each of the developer majors had his/her train ticket.
The group of testers had only ONE ticket for all of them. The developer majors started laughing and snickering.
Then, one of the testers said, "Here comes the conductor" and then all of the testers went into the bathroom.
The developer majors were puzzled.
The conductor came aboard and said "tickets please" and got tickets from all the developer majors. He then went to the bathroom and knocked on the door and said "ticket please" and the testers stuck the ticket under the door.
The conductor took it and then the testers came out of the bathroom a few minutes later.
The developer majors felt really stupid. So, on the way back from the convention, the group of developer majors had one ticket for the group.
They started snickering at the testers, for the whole group had no tickets amongst them.
Then, the tester lookout said "Conductor coming!" All the testers went to one bathroom. All the developer majors went to another bathroom.
Then, before the conductor came on board, one of the testers left the bathroom, knocked on the other bathroom, and said "ticket please."
Lesson learned: Any test that passed in unit testing can fail in system testing.
