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.
