Which of the following automation tool is used for functional regression testing in IZI program?
-
Quick Test Professional
-
SOA tool
-
Load Runner
-
Selenium
Quick Test Professional (QTP), now known as Unified Functional Testing (UFT), is designed specifically for functional and regression testing of applications. Load Runner is for performance testing, Selenium primarily for web functional automation, and SOA tool is too vague to be the standard functional regression tool.
Quick Test Professional (QTP, now UFT) is a scripted functional/regression test automation tool built for exactly this purpose — recording and replaying UI-driven test suites across runs to catch regressions. Selenium is also a functional tool but is web-only and open-source (a plausible but secondary distractor here), LoadRunner is a performance/load-testing tool rather than functional regression, and "SOA tool" targets service-layer/API testing, not general functional regression. QTP best matches the description given.
