Introduction

Testing whether a web page meets the Web Content Accessibility Guidelines is not always easy.

Fortunately, there are tools like WeBAIM's WAVE that make it possible to quickly run a number of automatic tests.

A web page that fails this test does not meet web content accessibility guidelines. A web page that does pass may meet web content accessibility guidelines. Additional investigation may be required.

 

Method of measurement

For this test we visit the homepage of the speed test and test this web page with WeBAIM's WAVE.

WAVE can identify many accessibility and Web Content Accessibility Guideline (WCAG) errors.

 

Speed tests to test

Because this is a relative simple test, the unique speed tests as collected at ZOMDir will be tested.
