What are different types of non-functional tests?

 

Performance Testing: Evaluates the system's responsiveness and stability under different conditions.

• Load Testing: Assesses performance under expected user loads.
• Stress Testing: Determines the system’s breaking point by pushing it beyond normal operating conditions.

Usability Testing: Measures how user-friendly the software is by gathering feedback from real users. Companies like WhatsApp and Telegram conduct usability studies where participants interact with prototypes while being observed, allowing for design improvements based on user behavior.

Security Testing (Penetration Testing): Identifies vulnerabilities in the system to ensure customer data, servers, and infrastructure are secure. It helps detect security flaws before they can be exploited, protecting sensitive information from cyber threats.

Compatibility Testing: Ensures the software functions correctly across various platforms, including web browsers (Chrome, Safari, Edge) and mobile devices (iPhones, iPads, Android tablets). This is crucial for applications that need to provide a seamless experience across multiple operating systems.

A/B Testing (Split Testing): Compares two variations of a software feature (e.g., two different UI designs) by deploying both versions to different user groups. Metrics like engagement, click rates, and session duration help determine which design performs better.

Disaster Recovery Testing: Assesses an organization's ability to restore IT infrastructure and resume operations after disruptions such as cyberattacks or natural disasters. This ensures minimal downtime and data loss by validating recovery strategies.
