What is ASLint?
ASLint is an accessibility validation utility. It is designed and created by Cezary Tomczyk of eSSENTIAL Accessibility.
Why was ASLint created?
- To work with Single Page Applications.
- To provide a simple explanation of each problem.
- To show the business impact so you can focus on which problem has to be fixed first.
- To easily plug-in to automated tests.
- Verify the accessibility of your content in real-time, including Single Page Applications.
- Review the results and determine the impact on the business.
- Does not send content or data externally, so it can be used for internal-only purposes.
- Tests can be run asynchronously (without blocking the UI) or synchronously.
- Provides a code snippet to add to a build pipeline (e.g. for automated tests) or the developer console, or can run as a bookmarklet.
- Easy locate issues on the page from the results using element highlighter or XPath
- Color contrast recommendations
- Provides a checklist for things that can’t be tested automatically.
- Provides WCAG 2.0 level A, AA, AAA, and Section 508 tests.
- Provides our proprietary eSSENTIAL best practice tests covering issues that aren’t included in Section 508 or WCAG.
- Provides the option to emulate High Contrast Mode (experimental).
- Every report contains:
- an explanation of the issue,
- what’s causing the issue,
- options to locate the visible element or by XPath,
- user impact,
- and links to external resources (where available) to get more details about the issue.
