Mobile App Accessibility Testing 101 WCAG Compliance and Best Practices
By BrowserStack, mobile app accessibility testing verifies that apps are accessible
to all individuals, especially embracing those with disabilities. The process involves assessing
the design, content, and functioning of an application Toneshare that it adheres to WCAG, Web Content Accessibility Guidelines, Accessibility Standards.
It is compatible with assistive technology like screen readers, voice controls, and alternate
input methods. Backslash dot. Here's why you need mobile app accessibility testing legal compliance.
Adhering to digital accessibility laws,
like the ADA and European Accessibility Act, prevents legal issues, fines, and damage to reputation. Inclusion and equal access. Accessibility testing ensures mobile apps
are usable by individuals with disabilities, promoting equitable access and inclusivity.
Wider audience reach. Accessible apps can engage a broader audience, including
millions with disabilities, enhancing user experience and creating new market opportunities.
Enhanced user experience. Accessibility features, such as clear navigation and intuitive design,
often improve overall user satisfaction and app ratings.
Social responsibility. Committing to accessibility reflects a company's dedication
to inclusivity and social responsibility. Avoiding rework and cost. Early accessibility
testing helps prevent costly redesigns and fixes, reducing customer complaints and post-launch
issues. WCAG compliance for mobile app ACCESSIBILITY WCAG, Web Content Accessibility Guidelines,
compliance is critical for making mobile apps accessible to people with disabilities.
While originally created for web content, WCAG concepts and criteria can also be applied to
mobile apps. Here's how WCAG compliance impacts mobile app accessibility.
1. Perceivable provide perceivable text
replacements for non-text items, including photos or icons. For example, including alt text for
photos or icon labels ensures that screen readers can communicate these items to visually challenged
users. Backslash dot. Ensure that content may be delivered in many formats, e.g. a simpler layout,
without losing information. For mobile apps, this could include giving a landscape and portrait
mode that remains accessible. Make it easier for users to view and hear material by ensuring
enough contrast between text and backdrop colors and offering choices for modifying text size and
volume without interfering with the app's operation. Backslash dot 2. Operable
all program capabilities should be accessible using a keyboard or keyboard-like input,
such as switches for users with mobility disabilities. This encompasses navigational
controls, forms, and interactive features. Allow users adequate time to read and consume content
by avoiding automatically advancing screens or timing out sessions too
rapidly. Avoid content that may provoke seizures, such as bright lights or quick screen updates.
Provide options for users to navigate, find content, and determine their location within
the app. This includes clearly labeled buttons and consistent navigation patterns.
Backslash.3. Understandable make written information readable and understandable.
This includes utilizing basic language, avoiding jargon, and ensuring that the material is readable
by screen readers. Web pages should appear and function in predictable ways. For example,
a button should act consistently across the program and content should not shift unexpectedly.
Help users prevent and fix errors. This includes clear
error notifications and easily accessible assistance resources. Backslash dot. 4. Robust
make sure the app works with current and future assistive technology like screen readers, voice
control, and magnifiers. Use good coding techniques to ensure that the app works with a variety of
user agents, including operating systems, browsers, and assistive devices. WCAG Levels of Compliance and Level A. Basic web
accessibility features, the minimum level. Essential for achieving the most critical
accessibility requirements. Level A. Addresses the largest and most typical barriers for handicapped
users. Often seen as an appropriate level for
public-facing digital products. Level AAA. The most advanced and comprehensive degree of
accessibility. Meeting all level AAA standards is ideal, however, it is not always feasible for all
material genres. Example of mobile app accessibility testing equals equals example 1. Testing with screen readers equals equals process.
Use a screen reader like VoiceOver, iOS, or TalkBack, Android, to navigate through the app.

Testing Here's a 5-step checklist for achieving mobile app accessibility.. General guidelines ensure the app has a clear title. Maintain a
proper heading hierarchy throughout the app. Utilize ARIA landmark roles, such as search,
navigation, content info, complementary, and banner, to structure the app or page effectively.
For touch events, adhere to one of these conditions. Avoid starting any
activity with a down event. Begin actions with an up event, with the option to cancel or reverse
the action before completion. Use the up event to undo actions initiated by a down event.
Start actions only after a clear indication of user intent. Ensure touch targets are sufficiently
large to be easily tapped. 2. Color contrast
ratios adhere to WCAG 2.1a level color contrast requirements to aid visually impaired users.
Achieve a 4.5 to 1 contrast ratio for standard text. Maintain a 3 to 1 contrast ratio for large
text. Ensure that color-based information is also accessible through other means.
3. Touch gestures and haptic feedback. 3. Touch gestures and haptic feedback Implement touch gestures and haptic
feedback to enhance the app's functionality and user experience on both Android and iOS.
While basic operations don't depend on touch gestures, they can improve accessibility and
appeal, particularly for users with limited reading abilities.
4. Consistent layouts and navigation
Maintain consistency in content, layout, and navigation to improve user experience.
Design mobile apps with assistive navigation to guide users through menus,
especially for those with motor impairments who may prefer mobile apps over web browsers.
Ensure layouts are well-organized and visually balanced to avoid confusion and enhance
accessibility.
5. Optimize app content, media
Adapt app content and media to be viewable on both small and large screens.
Ensure interactive elements, such as click, options and shopping cart functionalities,
are user-friendly and accessible.
Use legible header tags and optimize content layout to aid users with cognitive disabilities
in understanding and navigating the app. Provide clear captions for visuals to support accessibility
for both hearing and visually impaired users. Incorporating accessibility into mobile app
development is not only a legal or ethical requirement, but also a necessary component
of offering an inclusive OUSER experience. By following established principles,
using both automated and manual testing methods, and involving real users with impairments,
you can ensure that your software is accessible to all. Touch targets, color contrasts,
and information display may all be optimized on a regular basis to better match the demands of
various users. By using BrowserStack's platform, you can test your app on a wide
range of real devices, ensuring that accessibility features are functional and user-friendly across
different environments. This hands-on approach allows for more accurate assessments and helps
in identifying and resolving accessibility issues that automated tools alone might miss.
