Synopsis

Page: Pfizer (100%)

Score: 3023

Tested by: Testaro, procedure tp15

Scored by: Testilo, procedure sp15c

Digested by: Testilo, procedure dp15a

Introduction

The Testaro application used its tp15 testing procedure to test the accessibility (barrier-free design and coding) of the Pfizer (100%) web page at https://www.pfizer.com/ on 2022/08/13. The procedure performed 1230 tests. Of these, 24 are custom tests defined by Testaro, and the others belong to these seven other packages (programs that perform collections of tests):

Alfa by Siteimprove
Axe-core by Deque
Continuum by Level Access
HTML CodeSniffer by Squiz Labs
Equal Access by IBM
Nu Html Checker
Tenon by Level Access
WAVE by WebAIM

Testaro produced a report enumerating the test results.

Testilo processed the report and used the sp15c scoring procedure to compute partial and total scores for the page. The total score is 3023 (where 0 is the best possible score). The scored report is appended below.

Finally, Testilo used procedure dp15a to produce this digest, briefly explaining how sp15c computed the scores.

Issue summary

Special issues

log: Score 613. This is based on the amount of browser error logging and miscellaneous logging during the tests.
