UNICOM Intelligence web player and W3C compliance
World Wide Web Consortium (W3C) compliance guidelines covers a wide range of recommendations for making Web content more accessible. Following these guidelines will make content accessible to a wider range of people with disabilities, including blindness and low vision, deafness and hearing loss, learning disabilities, cognitive limitations, limited movement, speech disabilities, photosensitivity, and combinations of these. Following these guidelines will also often make Web content generally more usable.
Test objective
Run tests against the UNICOM Intelligence Web player, check for current W3C compliance, and determine the level of W3C compliance.
Testing tools
The Eclipse ACTF aDesigner application was used to perform the tests. After each Web page loaded, the Visualize blind usability was used to view the Web page errors.
Test environment
Server
Operating system: Microsoft Windows Server 2012 R2 (x64 64-bit)
Desktop
Operating system: Microsoft Windows 10 64-bit
aDesigner 1.4.0
Test data
A test project named ALLTYPE.mdd was use for testing. The test project covered most UNICOM Intelligence question types and Web page controls. The UNICOM Intelligence generated Web controls and elements were tested. As a result, no question or layout templates were used for the test project.
Test approach
The test project consisted of 22 pages (include Authentication and End pages). Each page displayed one question or question group (such as loop, compound, and page). The project was activated against a UNICOM Intelligence 6.0.1 server with sample management. Eclipse ACTF aDesigner was used to analyze the Web survey and record all errors in each page. Each page contained all possible options for the particular question or page type (for example, controls for Previous, Next, First, Last, Goto, Stop, and so on). The following pages were analyzed:
|
Authentication
|
Date and time question
|
|
Single response question
|
Display

|
Multiple response question
|
Compound

|
Single response grid
