;Feature <Ctrl-Tab > Test Plan

*First draft created 8-15-08
Owner: marcia@mozilla.org
= Overview =

The Ctrl-Tab feature introduces a scrolling tab filmstrip panel that is invoked when you press Ctrl-Tab. It allows the user to cycle through a set of tabs both forward and backward and stop on an individual tab. There is also a plan for a tab preview mode.

The one particular challenge I can think of is the differences per platform in how key events may be handled (Mac 10.4 vs. 10.5) as well as some minor differences in Windows. 

= Test Strategy =

*Plan to test
**General Operation of Control Tab feature according to spec
***Scrolling, both forward and backward
***Confirm Releasing Tab and pressing it again moves to the next preview
***Confirm Pressing W closes the selected tab
***Confirm Releasing Ctrl switches to the selected tab
***Confirm Pressing Tab repeatedly with Control held down will cycle through thumbnails of the tabs you’ve visited in order, with each press of Tab going one thumbnail back in time.
***Confirm that holding down the tab cycles quickly through the tabs
***Confirm proper rending of tab, including favicon

*Invoking the Grid View - Ctrl+Shift+A / Cmd+Shift+A 
** Confirm Shows tabs from all open windows
** Confirm Tabs can be closed by middle clicking
** Confirm Search field filters tabs based on their titles and addresses, Enter selects the first tab

*Negative Testing
**Testing with machines that have Low memory configurations
**Extending boundaries – Testing with ~100 tabs open

*Interoperability with Existing Major Tab Extensions
**Basic testing to make sure feature is still usable with extensions installed

*Areas Covered by Developer Testing
**Browser Chrome Tests for: https://bugzilla.mozilla.org/show_bug.cgi?id=445369

*Testcases will mainly be created in Litmus
