Automated Testing 4 Oil
The more test cases you have the more difficult it is to keep them up-to-date and make them provide the same benefit they did at the time they were born and run successfully. More and more scripts will start to fail and if you don't have the time to analyze the root-cause and fix the scripts, the number of scripts printing red alarm signals increases.
You will start to become familiar with the fact, that some scripts always print red warnings and the day isn't far where you don't even notice anymore that more and more scripts suffer of the same issue.
Probably you don't even trust your scripts anymore since they may report so called false-negatives. Make sure you keep them up-to-date at the time they fail. We call that script maintenance, and yes, this not only applies to manual testing. It is especially true for automated testing, too.
This is my second cartoon published in a printed magazine (STQA Magazine, September/October 2010).
ThanX to Rich Hand and Janette Rovansek.
