Types of software testing

Functional Testing

Functional testing is a crucial component of software quality assurance. It focuses on verifying that the software meets its specified requirements and performs as expected. Here are some key aspects of functional testing:

Black-box testing: Evaluates functionality without examining internal code
White-box testing: Examines internal logic and code structure
Integration testing: Ensures different components work together seamlessly
User acceptance testing: Validates software from the end-user perspective

Non-Functional Testing

Non-functional testing assesses aspects of the software that are not directly related to specific behaviors but are essential for overall quality. This includes:

Performance testing: Evaluates speed, responsiveness, and stability
Security testing: Identifies vulnerabilities and ensures data protection
Usability testing: Assesses user-friendliness and intuitive design
