Introduction

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

Fortunately, there are tools like AChecker 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 the AChecker's Web Accessibility Checker.

For this test we use ACheckers's standard options (Guidelines to check against WCAG 2.0 (Level AA)).

 

Speed tests to test

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

Conclusions

Based on the above measurements, we conclude that:

  1. The minimum number of known problems is 0
  2. The maximum number of known problems is 128 (Fireprobe)
  3. The average number of known problems is 16
  4. The median of the number of known problems is 6
  5. There are 2 speed tests with 1 likely problem
  6. The minimum number of potential problems is 0
  7. The maximum number of potential problems is 468 (Bandwidth Place)
  8. The average number of potential problems is 122
  9. The median of the number of potential problems is 101

There are 3 speed tests without known problems. These speed tests are: Xfinity xFi Speed Test, Internet Speed at a Glance and Ookla Speedtest.
