Description

Introduction of Black Box Testing

Black Box Testing is a software testing technique that focuses on testing the functionality of an application without any knowledge of its internal workings or code. This method tests how the system behaves based on inputs, outputs, and overall functionality from the user’s perspective. It plays a key role in validating that the software behaves as expected, ensuring that all functional requirements are met and helping identify issues that affect user experience and system performance.

Prerequisites:

1. Basic understanding of software testing concepts.
2. Familiarity with software development processes (SDLC).
3. Knowledge of test case design and testing techniques (helpful but not mandatory).
4. Familiarity with different types of testing (e.g., functional, non-functional).
