Garbage data testing

Garbage data testing is where you test-to-fail. You’ve already proven that the software works as it should by testing-to-pass with boundary testing, sub-boundary testing, and default testing. Now it’s time to throw the trash at it.

Software testing purists might argue that this isn’t necessary, that if you’ve tested everything discussed so far you’ve proven the software will work. In the real world, however, there’s nothing wrong with seeing if the software will handle whatever a user can do to it.

So, with invalid, wrong, incorrect, and garbage data testing, have some fun. If the software wants numbers, give it letters. If it accepts only positive numbers, enter negative numbers. If it’s date sensitive, see if it’ll work correctly on the year 3000. Pretend to have “fat fingers” and press multiple keys at a time.
