https://owasp.org/www-project-web-security-testing-guide/ (Look for "Stable - PDF" for v5.0.0)
Note: As of my last update, the most widely adopted stable release is v4.2. OWASP released v5.0.0 in early 2024. This review assumes you are looking at the official v5 PDF from the OWASP Foundation. The OWASP Testing Guide v5 is a complete, ground-up rewrite of the industry standard for web application penetration testing. It moves beyond the "checklist" mentality of v4 to a risk-based, context-aware testing framework . It is no longer just a guide for security testers; it is a guide for developers, DevOps engineers, and application owners.
