Tools Used for Black Box Testing

Black box testing is an essential methodology in software testing that evaluates the functionality of an application without peering into its internal structures or workings. This approach primarily focuses on inputs and outputs, assessing how the system performs given specific inputs. The tools used for black box testing help streamline the process, ensuring that all features are tested thoroughly. Below, we delve into some of the most effective tools utilized in black box testing, providing insights into their functionalities and benefits.
