Understand Step Duration Calculations in Scenario Editor

Last reviewed: September 29, 2026
Use this article to choose and interpret AIQ step-duration metrics such as DOM Complete, Server Response Complete, Full Page Loaded, Script Time, Ajax Time, and Next Step Ready.
What changed in this article
Replaced Test Designer/Web Designer wording with Scenario Editor terminology while keeping browser PerformanceNavigationTiming context.
Clarified which timings come from the browser and which are calculated by AIQ, including the SPA behavior where browser timings may return 0.
Added guidance that Script Time is often closer to perceived user duration, while Ajax Time is mostly retained for backward compatibility.
Validation workflow
Select the timing option that matches the question being answered: browser timing, user-perceived step time, or SPA readiness.
Compare AIQ output with browser performance timing only for browser-provided metrics.
Document the selected timing option when sharing reports so reviewers interpret duration values correctly.
Review note: This update keeps the technical timing distinctions but removes older Designer/Web Designer naming and fixes readability around asynchronous behavior.
