Software developers and maintenance teams don’t always understand quality assurance and testing. Misconceptions often lead to antagonistic relationships between the two groups: The former wants to get the project out the door as quickly as possible, but the latter often “slows down” the process with testing for issues and vulnerabilities.
It’s time to dispel the common misconceptions and realize that both parties are equally valuable and have their place within the larger development cycle.
Automated Testing Finds All the Bugs
While automated testing can be useful in certain circumstances, you cannot completely rely on it. If you want it part of the mix as a “final check”, that’s fine. Automated testing, however, should be performed after manual testing.
According to Dot Graham, well-known software test consultant and author, “automated testing doesn’t come out of a box (or a download). You get an engine, but not a whole car.” She recommends keeping some tests manual.
Software Testers Don’t Need to be Involved Early in a Project
Many people in upper-management and developers feel that testers only need to plug into the project during the end stages. This couldn’t be farther from the truth. Testing must be added to project timelines and estimates before work is even started.
Plus, testing needs to occur throughout the project. If not, then projects will run over if testing takes longer than anticipated or if major bugs are found. If the latter happens, then work may have to be redone, causing further delays.
Anyone can be Testers
Some teams believe that developers can also do the testing since testers – in their opinion – don’t have advanced skill sets. Testers do have specialized skills that help them identify vulnerabilities and functionality issues. Another misconception is that testers don’t get along with developers so developers should do the testing to avoid conflict. This type of attitude can lead to lost revenue and project delays.
Testing Slows Down the Whole Process
If testers are brought into the project early enough, then testing can be done alongside development. Issues can be identified and fixed during individual sprints. Further, outside testing teams can assist with testing to ensure that project timelines are maintained.
