Overview

Purpose

WebGL 2 is based on OpenGL ES 3.0, and brings with it many improvements and additions to help developers create stunning visuals on the Web. WebGL 2 will raise many restrictions and add new capabilities compared to WebGL 1. For example, while WebGL 1 only required support for being able to render using 8 textures at a time, WebGL 2 raises this minimum limit to 32.

(quote from Martin Best from Mozilla)

Scope

Requirements for testing

Environments

Testing will be performed on the following OSes (both x86 & x64 infrastructures):

  • Windows 7
  • Windows 10
  • Ubuntu 16.04
  • Mac OS X 10.11
  • Mac OS X 10.12

Test Strategy

Test Objectives

This section details the progression test objectives that will be covered.

Ref Function Test Objective Evaluation Criteria Test Type
1 WebGL 2.0 is enabled Verify that the “webgl.enable-webgl2” is set to true in about:config Observe the pref value Manual
2 WebGL 2.0 functionality Verify that WebGL 2.0 demos work Visit demo Manual
3 Private Browsing Verify that the feature works while in private browsing Visit demo Manual
4 WebGL 2.0 is disabled Set “webgl.enable-webgl2” to false demo displays WebGL only and not WebGL 2.0 Manual

Builds

This section should contain links for builds with the feature -

  • Track the dates and build number where feature was merged to Aurora
  • Track the dates and build number where feature was merged to Release/Beta

Risk analysis

Risk areas Mitigation
External dependencies on WebGL 2.0 feature WebGL 2.0 feature is dependent on the graphic card the user uses, it might not support this technology and also on the complexity of the demos tested. Some demos might be too demanding for the graphic card and might not be displayed properly
