What is black box testing?

Overview: Black box testing scrutinizes software functionality without inspecting its internal code structure.

Purpose: Its goal is to evaluate software behavior based on expected outputs, irrespective of internal workings.

Methodology: Testers approach this testing as if the software were a sealed black box, focusing on inputs and outputs.

Techniques: It utilizes methods like equivalence partitioning and boundary value analysis to craft diverse test scenarios.

Independence: This method doesn't require knowledge of programming languages or internal designs.

Validation: Black box testing validates whether the software aligns with user requirements and specifications.

User-Centric: Emulates user interactions, ensuring the software functions seamlessly from a user's standpoint.

Error Detection: It aids in uncovering discrepancies between expected and actual outputs.

Coverage Limitation: Due to its external perspective, it might overlook intricate internal errors or paths.

Complementarity: Often combined with white box testing for comprehensive software assessment.
