Automation testing plays a vital role in ensuring the quality and efficiency of software applications. However, for web accessibility, manual testing alone may not be sufficient. That’s where the role of accessibility testing in automation testing comes into play. By integrating accessibility testing into automation frameworks and test suites, organizations can streamline identifying and addressing accessibility issues.
This introductory guide explores the significance of accessibility testing in automation testing, highlighting its benefits, challenges, and best practices. Discover how combining automation and accessibility testing can help create inclusive digital experiences for all users.
Understanding Accessibility Testing
Accessibility testing determines how accessible a product, service, or environment is to people with disabilities. This method often includes evaluating the product or service to ensure that it can be used readily by persons with a wide range of abilities, including those with visual, auditory, motor, and cognitive impairments. The goal of the accessibility test is to identify and remove any obstacles that would prevent persons with disabilities from fully utilizing it.
Which Types of Web Accessibility Testing Are There?
Web accessibility testing is crucial to ensuring that websites and web apps are usable by everyone, including people with impairments. The following are the two main types of web accessibility testing:
Manual Web Accessibility Testing:
This testing involves human testers who manually navigate through the website or application, using assistive technologies like screen readers, keyboard-only navigation, or voice commands. They evaluate various elements such as headings, links, images, forms, and multimedia to ensure they meet accessibility standards. Manual testing allows for a comprehensive assessment of the user experience and identifies specific accessibility issues that automated testing may overlook.
Automated Web Accessibility Testing:
Automated testing involves the use of specialized tools or software that scans web pages and detects potential accessibility issues based on predefined rules or guidelines (such as WCAG 2.0 or 2.1). These tools analyze the HTML, CSS, and other code components to identify elements that may pose accessibility challenges. Automated testing is effective for rapidly identifying common problems on numerous pages, but it might not be able to capture online accessibility fully or offer insights into the user experience.
Purpose For Accessibility Testing
Testing for accessibility is mainly done to make accommodations for those with disabilities, including:
Hearing Deficiency: Affected individuals cannot hear or hear clearly due to sensory problems, such as hearing loss or deafness.
Physical limitations: People with this kind of disability have hand fatigue, muscle retention, and decreased motor coordination.
“Visual impairments” covers a range of conditions, including total blindness, impaired vision, color blindness, issues with flashing effects, and visual strobe.
Cognitive Deficiency: A person with cognitive inadequacies will struggle to learn, will remember things poorly, and won’t be able to understand more complex situations..
Role of accessibility testing
Automation testing must include accessibility testing since it guarantees that services and software are usable by all users, including those with disabilities. It entails determining if a website, application, or software can be used and understood by persons with varying skills and limitations.
The role of accessibility testing in the context of automation testing is to add automated checks and validations that assess a product’s compliance with accessibility standards and guidelines. Here are some crucial characteristics of automated testing accessibility:
Compliance Testing
Automation testing can incorporate predetermined checks and validations based on accessibility standards such as the Web Content Accessibility Guidelines (WCAG). These automated tests can determine whether user interface elements such as buttons, forms, and menus follow accessibility rules in terms of structure, labeling, and behavior.
Keyboard Navigation
Automation tests can verify that a product’s interactive features can all be accessed and used solely with a keyboard. This is crucial for those whose navigation relies on the keyboard because of their motor difficulties or other disabilities. Automated checks can ensure that users can easily traverse the UI and that keyboard focus is effectively managed.
Screen Reader Support
Screen reader compatibility testing can be included in automation testing. Screen readers are assistive tools that people with vision impairments use to view digital content. Automated testing can determine whether the screen reader software can correctly comprehend and deliver the content to the user, including text, graphics, and interactive components.
Visual Elements and Color Contrast
Automated testing can assess the color contrast ratios of text and background combinations to ensure they meet accessibility standards. They can also determine whether visual features, such as icons and photos, have alternate text descriptions that make them comprehensible to people with visual impairments.
Form Field Verification
Form validation and error messaging can be validated using automation tests. This assists users with disabilities, who may rely on assistive technologies, in understanding and correcting any input errors or omissions.
Design for Mobile Devices
Automation accessibility testing might include checks for responsive design, which ensures that the product adapts and performs smoothly across different screen sizes and devices. This is critical for users who access digital information via mobile devices or assistive technologies with varying display capabilities.
Roles and Attributes of ARIA
Checks for the right implementation of Accessible Rich Internet Applications (ARIA) roles and attributes can be included in automation testing. ARIA improves web application accessibility by giving additional information and context to assistive technologies. Automated tests can guarantee that ARIA elements, like menus, tabs, and dialog boxes, are used correctly to improve the accessibility of interactive components.
Text Substitutes for Non-Textual Content
Automated testing can determine whether non-text items, such as photos, charts, and graphs, have text replacements. This ensures that people who cannot see the visual material can understand the information. Automation can verify that alt text or other equivalent methods are used correctly for certain items.
Audio and video accessibility
Automation testing can evaluate the accessibility of audio and visual features inside a product. This involves determining if closed captions or transcripts are provided for videos, making them accessible to those with hearing problems. Automated tests can also examine if audio elements have volume controls and can be paused or stopped by assistive technologies.
Emphasis On Management and Skip Links
Automation testing helps ensure that the emphasis of user interface components is appropriately handled. This is critical for users who use assistive technologies to navigate the UI. Additionally, automated tests can check for the availability of skip links, which allow visitors to bypass repetitious navigation elements and immediately access the core content of a page.
Accessibility API Testing
Automation can use Accessibility Application Programming Interfaces (APIs) supplied by operating systems and assistive technologies to test an application’s accessibility. These APIs allow automated tests to interface with assistive technologies and simulate user interactions, confirming that the application is compatible with and functions as intended with various assistive technologies.
Regression Testing
Accessibility testing in automation can be combined with regression testing to verify that new updates or changes to a product do not introduce accessibility concerns. Automated tests can be conducted regularly to ensure the application’s continued compliance with accessibility standards, preventing regressions and ensuring a consistently accessible user experience.
Performance Enhancement
Automation tests can assess the impact of accessibility features and optimizations on performance. They can, for example, determine whether dynamically loaded material or interactions provided to improve accessibility harm the product’s overall performance.
How Do Accessibility Tests Work?
Accessibility testing can be done manually or automatically. To verify that all relevant regulations have been checked, applications must be tested for the following:
- Checking to see if the labels and text are universally accessible – It can evaluate an application’s capacity to determine whether users can still read text when labels and text are enlarged or shrunk.
- Check the image/text contrast to see if users can still use the application if the contrast has been increased more radically.
- It is being tested to see if visitors can still understand all of the information displayed on the webpage if the application’s style sheets fail.
- Testing the program’s hit area – To make the application more accessible to users, the hit area for more significant tasks should be user-friendly and entertaining.
- People with disabilities utilize assistive software, such as screen readers, keyboards with specific keys, and speech recognition applications, to complete a variety of tasks. As a result, an application’s interoperability improves a program’s accessibility with assistive technology.
