When programmers test their code, the need to come up with some kind of test data. And most programmers are not very creative (just as everybody else). Very often you can log into various websites with the login “firstname.lastname@example.org” and password “test”. I am afraid to even think about what email@example.com’s inbox contains. It’s a real email address you know, the emails don’t bounce.
Here are some interesting test strings:
Of course, everyone knows the famous “Hello, World” test string. I’ve heard that for the first time it appeared in the bible, but I am not sure.
The other most famous test strings are “foo” and “bar”, which apparently come from foobar, which is derived from WWII slang. FUBAR is a relative of SNAFU.
A professor that taught VB in college told us, that about the time he was developing a database application for a hospital. His favorite test person was James T. Kirk and his mates, and during testing the poor captain got every imaginable sort of ailment. With funny comments.
When I worked at iXL, our tech lead, a German by the name of Lothar, liked to use a string “4711” as most people use “foo”. Once, in a meeting he asked if anyone new why he was using “4711”. He was pretty surprised that I new what “4711” was. “4711” is what some of you may know as Koeln Water, which was the first commercially produced perfume. That’s where the term “cologne” came from. And “4711” is the number of the building where Koeln Water was produced.
I use “1729” for my testing needs sometimes.
