What is Software Testing? — UK Software Development Guide
Direct Answer
Software testing is the process of evaluating and verifying that a software application works correctly and meets requirements. Types of testing include: unit testing (testing individual functions), integration testing (testing component interactions), end-to-end testing (testing complete user journeys), performance testing (testing under load), security testing (finding vulnerabilities), and accessibility testing (testing for disabled users).
