What are the main types of software testing for web applications?
Web testing climbs four levels — unit, integration, system, and acceptance — each widening the scope from single functions to whole-business requirements.
| Test Type | Scope | Who |
|---|---|---|
| Unit | Individual functions/components | Developers |
| Integration | Multiple modules together | Developers/Testers |
| System | Entire application | Testers |
| Acceptance | Business requirements | Product Owner/Customer |
Testing criteria include functionality, efficiency, maintainability, portability, reliability, and usability (ISO 9126).
