Accessibility Testing
Introduced in GitLab 12.8.
If your application offers a web interface and you are using GitLab CI/CD, you can quickly determine the accessibility impact of pending code changes.
Overview
GitLab uses pa11y, a free and open source tool for
measuring the accessibility of web sites, and has built a simple
CI job template.
This job outputs accessibility violations, warnings, and notices for each page
analyzed to a file called accessibility.
Configure Accessibility Testing
This example shows how to run pa11y on your code with GitLab CI/CD using the GitLab Accessibility Docker image.
For GitLab 12.9 and later, to define the a11y job, you must
include the
Accessibility.gitlab-ci.yml template
included with your GitLab installation, as shown below.
Add the following to your .gitlab-ci.yml file:
variables:
a11y_urls: "https://about.gitlab.com https://gitlab.com/users/sign_in"
include:
- template: "Verify/Accessibility.gitlab-ci.yml"
creates an a11y job in your CI/CD pipeline, runs
Pa11y against the webpages defined in a11y_urls, and builds an HTML report for each.
The report for each URL is saved as an artifact that can be viewed directly in your browser.
A single accessibility.json artifact is created and saved along with the individual HTML reports.
It includes report data for all URLs scanned.
NOTE: Note:
For GitLab versions earlier than 12.9, you can use include:remote and use a
link to the current template in master
NOTE: Note: The job definition provided by the template does not support Kubernetes yet.
It is not yet possible to pass configurations into Pa11y via CI configuration. To change anything, copy the template to your CI file and make the desired edits.
