Non-Functional Testing

Non-Functional Testing is a type of software testing that focuses on evaluating the non-functional aspects of an application, such as performance, scalability, usability, reliability, and security. Unlike functional testing, which verifies specific features and functionality, non-functional testing assesses how well the software performs under various conditions and how it meets user expectations in terms of quality and system behavior.

Key components of non-functional testing include:

• Performance Testing: Evaluates how the software performs under different load conditions, measuring response time, throughput, and resource usage.
• Load Testing: Tests how the system handles a specific load or volume of users, ensuring that it can support expected traffic levels without performance degradation.
• Stress Testing: Assesses how the software behaves under extreme or unexpected conditions, such as high traffic or resource shortages, to identify its breaking point.
• Scalability Testing: Verifies that the application can scale effectively, handling increasing user demand or data volume without significant performance loss.
• Security Testing: Identifies vulnerabilities and ensures the application is protected from potential threats, including data breaches and unauthorized access.
• Usability Testing: Measures how user-friendly and intuitive the application is, ensuring that it provides a seamless user experience.
• Compatibility Testing: Ensures the software works across different platforms, browsers, devices, and operating systems.

Non-functional testing ensures that the software meets quality standards and performs reliably in real-world conditions, enhancing the overall user experience and system stability.
