Feature <Ctrl-Tab > Test Plan

• First draft created 8-15-08
• Revised 11-20-08

Update: This feature was pulled from Beta 2 per https://bugzilla.mozilla.org/show_bug.cgi?id=465843 Bug 465843]

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
    • Confirm proper rendering of tab when there is multiple content types in the tabs, such as any embedded plugins (Flash, Java, RealPlayer, etc.), and especially dynamic content (AJAX, DHTML animations).
      • Confirm they show properly in the preview
    • Interoperability with the Esc key
      • Does it properly close the tab preview?
    • Confirm Opening multiple tabs in two windows, and ensure that the set for the current window is correct.
      • Confirm a window with multiple tabs doesn't show up when you try to preview a window with less than 3 tabs.
    • Confirm Aero Glass displays in Ctrl-Tab

• 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
  • http://mxr.mozilla.org/mozilla-central/source/browser/base/content/test/browser_ctrlTab.js

• Testcases will mainly be created in Litmus

Schedule Scoping

• Major feature has been landed. Awaiting the landing of the preview mode.
• Planned testing of Features
  • Testing of nightly checkins
  • Full run through the Tabbed Browsing FFT to catch any possible regressions
  • Install and check several major extensions
