Testing vs Quality Assurance vs. Quality Control What's the Difference?
A product, an application, a website, the success of all these do depend on the functionalities built into them. But answer to some questions like “How easy they were to use? How easy were they to understand? Did they do the job without any errors?”, ‘quality’ becomes the most important factor of it all. A developer may build the functionality but a tester determines the quality of the software and how well they were built.
