Changing a setting does not change page context
What this criterion checks
This criterion maps to 3.2.2 On Input. A detailed plain-language description is maintained in the WebLens criteria catalogue; the WCAG sub-test breakdown below describes exactly what the agent checks and what it does not.
How it's assessed
WebLens walks each user journey, captures a screenshot at every step, and an agent reasons over that evidence. See the how WebLens works for the full pipeline and the deterministic checks layered in for accessibility.
Sub-test coverage
3.2.2 On Input is broken into 2 sub-tests. Coverage is honest about where the agent is reliable, where it only partially checks the requirement, and where a human reviewer is still needed.
1 partial1 not covered
- Changing a form control setting does not take the user somewhere unexpectedPartial
Our tool changes the value of form controls (dropdowns, checkboxes, radio buttons, text fields) one at a time and checks whether the page navigates away, opens a new window, shows a dialog, or jumps focus to an unrelated area. These are the most common ways users get disoriented by "on input" behavior. What still needs manual review: controls inside embedded frames, range sliders, and single-page applications that reload content without changing the page address. Also, applications that submit data silently in the background without using a standard form may not be caught.
- User is warned in advance when a setting change will cause a disruptive changeNot covered
When a form control does cause a disruptive change (like a dropdown that reloads the page), the criterion allows it if users are told beforehand — for example, a note that says "Selecting a country will reload prices." Our tool flags the disruptive behavior but does not check whether a warning was provided near the control. A person needs to verify whether any flagged behavior was properly disclosed to users before they reached that control.
How reliable it is
This criterion is still building up testing data, so confirm its findings as you review. See Accuracy & confidence for how the confidence tags are set.
