Why Does Validation Testing Matter in Software Engineering?
Most software bugs could be traced to validation mistakes. Think about building an app on paper that has no bugs and is flawless, but when they release it to the end user, they keep encountering problems since the software never addresses their problem or fulfills their requirements due to poor data validation. This is where software testing and validation testing enter the picture. It's the activity of making sure the software you've built satisfies end-user expectations, not only technical requirements.
