Software testing is a process of executing a program or application with the intent of finding the software bugs. It can also be stated as the process of validating and verifying that a software program or application or product. Meets the business and technical requirements that guided its design and development, Works as expected and can be implemented with the same characteristic. Automated software testing utilizes different tools to execute testing activities. In this paper, I have discussed the features of Security Testing Tools: Wapiti, OWASP ZAP and Netsparker. In brief, I have presented a detailed description focusing on multiple feature Authentication, Control and Connection Features, Coverage Features, Input Vector Support, Audit Features, Complimentary Audit Features, The SQL Injection Detection Accuracy of the Scanner, The Reflected XSS Detection Accuracy of the Scanner, The Path Traversal / Local File Inclusion Detection Accuracy of the Scanner, The Remote File Inclusion Detection Accuracy of the Scanner, The WIVET Score of the Scanner. Finally, this research allowed me to draw some solid differences between Security Testing Tools by having real -world experience of testing effectively.
