Black Box Testing Definition

Black box testing — is a method in quality assurance testing that involves the actual tester being oblivious to the processes of how internal workings operate neither its structure. With the main goal of such testing is to evaluate the functionality of the system in condition where inputs generate outputs. The term “black box” in this setting illustrates that only observable behavior of the software is important.

It is a useful method which explains its popularity because it lets testers step into the shoes of end users and monitor how the software responds to predictable actions of users, what its response time is, how it adheres to requirements, etc. Which especially simulates an environment of users only caring about functionality and not the assembly of code behind it.
