About automated a11y testing

The Web Content Accessibility Guidelines (WCAG) are the basis for all digital accessibility regulations in the US, Canada, and Europe, including the Americans with Disabilities Act and Section 508, Canada’s ACA, and EN 301 549 in the EU. On top of WCAG, Apple's Human Interaction Guidelines (HIG) and Android Accessibility Guidelines define the standards for any app listed in the App Store or Google Play.
‍
Accessibility isn’t one-size-fits-all. QA Wolf tests your browser-based app using WCAG standards—and your iOS and Android apps using platform-specific guidelines like Apple’s Human Interface Guidelines and Android Accessibility Guidelines. We test for compatibility with screen readers like VoiceOver and TalkBack, and ensure key accessibility features like labeling, touch targets, and text scaling are working correctly.

How it's done

3 accessibility levels: minimum, recommended, highest

Define your test cases

We’ll outline and build regression tests according to the WCAG success criteria you're targeting, and ensure you're compliant with HIG and Android Accessibility.

Not sure what you need? We’ll help you decide as we build out a test plan.

Test on-schedule or on-demand

We use Google Lighthouse and the Axe library to assert that browser-based apps meet the accessibility standard you’re targeting.

Android emulators and real iOS devices run inside QA Wolf's private device cloud.

Release when clear

Any accessibility issues get filed as bug reports in your issue tracker, alongside the functional regressions we catch during testing.

Accessibility means P.O.U.R.

WCAG's  four principles of accessibility — Perceivable, Operable, Understandable, and Robust — underpin HIG and Android Accessibility Guidelines. Our QA engineers build and maintain test cases for all of them.

Perceivable

Alternatives for non-text content

Assert that “programmatically determinable” alt text that screen readers and other adaptive tech can use is provided for pictures, charts, and other visuals; and transcriptions are provided for audio and video content.

Adaptable content

Test that assistive technologies can determine how to render the content of your application.

Distinguishable content

Validate color contrast, dynamic type, responsive layouts, hover and focus states, audio balance, etc. so users can separate what’s in the background and foreground.

Operable

Keyboard accessibility

Test that your whole app can be used through the keyboard alone, and assistive technologies that navigate by simulating keystrokes.

Timing

Assert that users have enough time to interact with your app, and the ability to delay actions if they need more time.

Photo sensitivity

Catch animations and other types of flashing content that can cause seizures or other physical affects.

Navigation aids

Test that critical navigation aids like page titles, sequential focus order, and focus visibility are present after each release.

Input devices

Make sure your app can be used with finger inputs, styluses, pointers, and a mouse — concurrently — and that gestures, target areas, and motion meet WCAG, HIG, and Android standards for usability.

Understandable

Readable language

Check that your app has a defined “human language” that are used by screen readers and other assistive tech.

Input assistance

Test for WCAG-compliant instructions and error messages and the proper ‘aria’ labels.

Predictable interactions

Catch components that trigger changes automatically without a user’s confirmation.

Robust

Compatibility with assistive tech

Catch poorly formed markup and other problems that would challenge today’s and the future’s assistive technology.
