These four levels provide a structured approach to testing software throughout its development lifecycle, from individual components to the complete system, ensuring its quality and reliability.
Let’s explore them:
- Unit Testing: Ensuring the building blocks are rock-solid! Developers rigorously test individual components to validate their functionality, setting the stage for a robust foundation.
- Integration Testing: Harmonizing the ensemble! This level focuses on testing the interaction between integrated units, guaranteeing seamless collaboration and smooth data flow.
- System Testing: Evaluating the big picture! The entire system undergoes scrutiny to ensure it aligns with requirements and operates flawlessly in its intended environment, covering functional, performance, usability, and security aspects.
- Acceptance Testing: Embracing user feedback! From User Acceptance Testing (UAT) to alpha and beta tests, this level evaluates the system’s compliance with user requirements, business requirements, and owner requirements.
