Some other funny causes I've seen: - The temperature is much hotter/colder than normal - Someone is inadvertently holding down a button or key on the machine under test - The wrong version of software is loaded onto the machine |

I like this 1999 story about a flaky test at Be:
> Two test engineers were in a crunch. The floppy drive they were currently testing would work all day while they ran a variety of stress tests, but the exact same tests would run for only eight hours at night. After a few days of double-checking the hardware, the testing procedure, and the recording devices, they decided to stay the night and watch what happened. For eight hours they stared at the floppy drive and drank espresso. The long dark night slowly turned into day and the sun shone in the window. The angled sunlight triggered the write-protection mechanism, which caused a write failure. A new casing was designed and the problem was solved. Who knew?
