Developer QA Review

The QA person responsible for the feature should hold a formal interview with the lead developer or feature champion. Below are questions that should be asked in the interview:

• Do we have automated tests for the feature?
• What do they cover?
• What do they not cover?
• How well do they cover the feature?
• What are the important areas we should focus on?
• What are the dependencies?
• What is our comfort level with this feature in its current state?
• What feedback would you like from QA?

Mozmill Tests

If a particular feature needs manual tests which should also be covered by Mozmill tests please add the "[mozmill-test-needed]" whiteboard entry to the feature implementation or regression bug.

Manual Tests Details

• Enabling the feature
  • Go to about:config
  • Click through the warning, if necessary
  • Enter 'render' in the 'Filter' box
  • Double-click on 'gfx.font_rendering.directwrite.enabled' to set it to true
  • Double click on 'mozilla.widget.render-mode', set the value to 6
  • Restart

• Manual Tests
  • Flickering, shadowing, or graphic artifacts when doing things like scrolling, switching between multiple tabs, and playing videos. Like Grafx Bot, ideally these kinds of manual tests should be run on as many different hardware combinations as possible, so maybe they'd be good to combine with Grafx Bot in a testday.
