Mobile App Accessibility Testing Checklist

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 to ensure 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. 

The objective is to establish an all-encompassing user experience that caters to a wide range of requirements, guaranteeing equitable availability of information and functionality for every user.

What is Mobile App Accessibility Testing?

Mobile App Accessibility Testing is the process of determining if a mobile application is accessible to all users, including those with impairments. This testing ensures that the app’s interface, content, and features can be utilized effectively by those with visual, aural, motor, or cognitive impairments. 

It involves testing the app’s compatibility with assistive technologies such as screen readers, voice commands, and alternative input methods. 

Mobile App Accessibility Testing also ensures that the app meets established accessibility standards such as the Web Content Accessibility Guidelines (WCAG). 

The goal is to design an all-inclusive software that provides equal access and usefulness to all users, regardless of ability.

The Need for Mobile App Accessibility Testing

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.
• 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.

2. Operable

• Keyboard Accessibility: 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.

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.
• Predictable User Interface: 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.
• Input Assistance: Help users prevent and fix errors. This includes clear error notifications and easily accessible assistance resources.

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

• Level A: Basic web accessibility features (the minimum level). Essential for achieving the most critical accessibility requirements.
• Level AA: 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.

Testing Procedures for WCAG Compliance in Mobile Apps

• Manual testing involves using the app with assistive technology such as screen readers, assessing colour contrast and letter sizes, and navigating the app with a keyboard.
• User Testing involves people with impairments in the testing process and gives real-world feedback on the app’s accessibility.

Example of Mobile App Accessibility Testing

Here are some of the examples of Mobile App Accessibility Testing:

Example 1:  Testing with Screen Readers

• Process: Use a screen reader like VoiceOver (iOS) or TalkBack (Android) to navigate through the app. The tester should ensure that all elements are announced correctly and that the navigation flow is logical and intuitive.
• Objective: Verify that all interactive elements (buttons, links, form fields) are labeled correctly and provide sufficient context to the user.
• Outcome: You might discover that some buttons lack descriptive labels, making it difficult for visually impaired users to understand their purpose.

Example 2: Color Contrast Testing

• Process: Manually check the contrast ratio between text and background colors using a color contrast tool or by visual inspection.
• Objective: Ensure that the text is easily readable for users with visual impairments, especially those with color blindness.
• Outcome: You may find that certain text elements have insufficient contrast, making them hard to read.
