Test Data

Purpose

TCDL Data

sc3.2.5_l3_053 (XML).

Rules

“Rules” refer to success criteria in WCAG 2.0, checkpoints in WCAG 1.0 and similar requirements.

Primary Rules

The test case passes the following success criterion: http://www.w3.org/TR/2006/WD-WCAG20-20060427/guidelines.html#consistent-behavior-no-extreme-changes-context.

Functional Outcome

The user initiated the change of context, and expected it to be connected to the user's action.

Technical Comment

This test case uses the same code as sc3.2.5_l3_026, but adds a warning.

The actual behaviour depends on the user agent. On Windows XP, the following behaviour was observed. In Firefox 2.0 and SeaMonkey 1.1: if the window was maximized, it is resized before it is moved, otherwise it is just moved. In Internet Explorer 6: the window is moved, regardless whether it was maximized or not. In Opera 9: nothing happens, regardless whether the browser window was maximized or not. If Internet Explorer 6, Opera 9, Firefox 2.0 and SeaMonkey 1.1 are in full-screen mode (which can be toggled with F11), the window does not move either.

Secondary Rules

Secondary Rule (WCAG 2.0 - June 2005 Working Draft)

The test case passes the following success criterion: http://www.w3.org/TR/2006/WD-WCAG20-20050630/#consistent-behavior-no-extreme-changes-context.

Functional Outcome

The user initiated the change of context.

Technical Comment

The user moved the focus to another link, which initiated a change of viewport.
