Test Data

Purpose

The test is intended to pass because the change of viewport was expected.

Expert Guidance

The browser must be JavaScript-enabled. The browser window must not be maximized or full-screen. In Opera use overlapping windows (Shift+F5).

Test Modes

Accessibility expert.

Test Files

TCDL Data

sc3.2.5_l3_049 (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 (line 9, column 82) the following success criterion: http://www.w3.org/TR/2007/WD-WCAG20-20070517/Overview.html#consistent-behavior-no-extreme-changes-context.

The test case passes (line 9, column 153) the following success criterion: http://www.w3.org/TR/2007/WD-WCAG20-20070517/Overview.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

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 6.0, the window is moved, regardless whether it was maximized or not. In Opera 9.0: the window is only resized if the view has been changed to "overlapping windows" (Shift+F5. If Internet Explorer 6.0, Opera 9.0, Firefox 2.0 and SeaMonkey 1.1 are in full-screen mode (which can be toggled with F11), the window does not move either.

This test case does not map to a WCAG 2.0 technique or failure.
