What is ASLint

ASLint is an Accessibility validation utility. It is designed and created by Cezary Tomczyk.

Couple of reasons why ASLint has been created:

  • To work with Single Page Applications model.
  • To provide simple explanation of the problem. At least that’s the goal.
  • To show what’s the impact on the business so you can focus on which problems has to be fixed first.
  • Easy plug-in into automation tests.

Features

  • Verify accessibility of your content in real-time, including Single Page Applications.
  • Review results and determine the impact on the business.
  • Does not send content or data externally, so can be used for internal-only purposes.
  • Tests can be run asynchronously (without blocking the UI) or synchronously.
  • Provides code snippet to add to build pipeline (e.g. for automation tests) or developer console, or can run as a bookmarklet.
  • Easy locating issues on the page from the results using element detector or XPath
  • Color contrast recommendations
  • Provides checklist for things that can’t be tested automatically.
  • Provides WCAG level 1,2,3 and Section 508 tests.
  • Provides tests that aren’t included in WCAG or Section 508.
  • Provides option to emulate High Contrast Mode (experimental).
  • Every report contains:
    • explanation of issue,
    • what’s causing issue,
    • options to locate visible element or by XPath,
    • determine impact,
    • contains (if possible) links to external resources to get more details about the issue.
