When I say quality testing many software developers and others in the computer science field may think I am referring to testing the quality of software. While in many instances this may be the case, here I would like to point out the importance of quality testing; or creating tests with a high level of quality to ensure working software.
Before delving into why it’s so important it might be beneficial to highlight just how disastrous dysfunctional code can be. According to Harry Ngyuen in his blog “Top 8 Reason Why Software Testing Is Important In 2025“, fixing a bug that has made it the maintenance phase can cost 10 times more to fix than it does during the design phase.
As he also mentions many customers expect fast and high-quality applications and if these expectations are not met many customers may switch their provider. As well as customer satisfaction many risks can come with buggy software creating security hazards.
Clearly having buggy code that was haphazardly tested is incredibly detrimental to any software being released by a single developer or even an entire organization. So how do we ensure this doesn’t happen?
There is a magnitude of ways to test code, and I don’t think listing them out will help with our cause as there is no best way. To ensure high quality software you mut write high quality tests.
Your tests have to be able to accurately track the flow of your program, be able to highlight where something failed and why it failed, and ensure all boundaries are tested and a successful output is what you’re left with. This means writing as many tests as needed, whether its five or fifty. It means writing tests that check whether your application can handle anything thrown at it. Testing can take time and effort but it’s much better to spend that time while writing your code and handling the bugs one at a time than to have to deal with many after a release has occured.
I plan on continuing down the road of software development both in my student career and my professional career. With this in mind, I will ensure I apply my quality testing skills to produce the highest quality software I can.
