<p>We use <code>pa11y-ci</code> to run our accesibility testing on all GNU social
|
|
|
|
|
pages. The process of setting this up was a bit of a ride, but the
|
|
|
|
|
results are quite useful:</p>
|
|
|
|
|
|
|
|
|
|
<p><img src="assets/a11y/report.png" alt="Accesibility report generated by Pa11y" title="" /></p>
|
|
|
|
|
|
|
|
|
|
<p>We also take screenshots of all pages and compare them with the
|
|
|
|
|
previous, allowing us to spot (possibly) unintended changes in the UI.</p>
|
|
|
|
|
|
|
|
|
|
<p>The way we do this is by using a <code>docker</code> image derived from <code>node</code>,
|
|
|
|
|
with <code>pa11y-ci</code> installed, which doesn't have an entrypoint. This then
|
|
|
|
|
allows us to spin up a webserver, PHP and Redis containers, mimiking a
|
|
|
|
|
staging environment. <code>pa11y-ci</code> uses a JSON config file to tell it
|
|
|
|
|
what to do, and handles visiting all pages with the given resolution,
|
|
|
|
|
logging in and registering any accesibility violations found.</p>
|
|
|
|
|
|
|
|
|
|
<p><img src="assets/a11y/violations.png" alt="Accesibility violations found by Pa11y" title="" /></p>
|
|
|
|
|
|
|
|
|
|
<p>Note that most of these errors are actually the same.</p>
|
|
|
|
|
|
|
|
|
|
<p>The saved screenshots are then used to detect changes, with
|
|
|
|
|
ImageMagik's <code>compare</code>, to generate a report on visual changes.</p>
|
|
|
|
|
|
|
|
|
|
<p><img src="assets/a11y/compare.png" alt="Screenshot comparisons" title="" /></p>
|
|
|
|
|
|
|
|
|
|
<p>We were already striving for making GNU social accesible, which is
|
|
|
|
|
clear from the really low number of violations found, but there's
|
|
|
|
|
always room for improvement :)</p>
