Comprehensive Web App Testing

My web application is nearly ready for launch and now needs a final, end-to-end test cycle. The mandate covers functionality, usability, and security verification on the latest releases of Google Chrome, Mozilla Firefox, and Safari. A blend of manual exploration and automated scripts (e.g., Selenium/WebDriver, Postman, OWASP ZAP) is welcome as long as every defect is clearly documented with reproduction steps, screenshots or video, and severity tagging.

Deliverables
• Test plan detailing scenarios for functionality, usability, and security
• Executed test cases with pass/fail status and evidence
• Defect log with prioritised issues and retest outcomes
• Final report summarising coverage, residual risks, and actionable recommendations

Acceptance criteria
All identified high- and critical-severity issues are fixed and retested, the test report is complete, and coverage across Chrome, Firefox, and Safari is demonstrated.
