5. Black Box Testing
Black box testing is often considered under functional testing and categorized as software acceptance testing. It is because it shares similar principles and practices as User Acceptance Testing.
Black box testing helps analyze some software product functionality without the need to look at the internal code structure.
It focuses mainly on the requirements that software must meet, and the user is unaware of any codebase.
Similarly, testers do not necessarily have to look deeper into the application features. And testers are only concerned about how the software must perform based on the requirements. As it offers great benefits to software testing, it’s quite popular amongst QA and development teams.
