Canvas - A QUnit Addon For Testing Canvas Rendering

This addon for QUnit adds a pixelEqual method that allows you to assert individual pixel values in a given canvas.

Usage:

pixelEqual(canvas, x, y, r, g, b, a, message)

Where:

• canvas: Reference to a canvas element
• x, y: Coordinates of the pixel to test
• r, g, b, a: The color and opacity value of the pixel that you except
• message: Optional message, same as for other assertions
