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.
