Accessibility test digest

Introduction

The Testaro application used its tp15 testing procedure to test the accessibility (barrier-free design and coding) of the Nestlé USA (100%) web page at https://www.nestleusa.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 2158 (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.

Score summary

Issue summary

Special issues

log: Score 1145. This is based on the amount of browser error logging and miscellaneous logging during the tests.

preventions: Score 100. This is based on tests that the page did not allow to be run. That impedes accessibility progress and risks interfering with tools that users with disabilities need.
