Feature WHATWG Canvas Test Plan

Overview

This feature implements HTML5 compliance of text and shadows.

Test Strategy

Testcases will be covered in reftests and mochikit tests. See:

• reftests - layout/reftests/canvas/)
• mochitests - (in content/canvas/tests/test_text*)

Schedule Scoping

Tests have been checked in since beta 1. Only open issue for 3.1 is that erroneous arguments are not ignored. The spec says invalid arguments should be ignored, but Vlad wanted Firefox to return error codes instead. But the rest of Canvas already does this, anyway.
