Performance testing is essential for understanding how systems behave under load. Slow API responses may indicate database bottlenecks, inefficient queries, or infrastructure limitations.
A strong automation framework should include reusable utilities, clean architecture, logging, reporting, and proper error handling. These practices simplify long-term maintenance.
Well-structured test data improves reliability and reduces flaky test behavior. Dynamic data generation helps avoid conflicts between test executions.
Security testing is becoming increasingly important for web applications. Authentication, authorization, and sensitive data validation should always be covered by automated tests.
