Fact: Accessibility testing is vital in today’s digital landscape, given that over 1 billion people (about 15% of the global population) live with disabilities, including 2.2 billion with vision impairments and 466 million with hearing loss.
What is an accessibility keyboard?
An accessibility keyboard is a special type of keyboard designed to help people with disabilities use a computer more easily. It has features that make typing and navigating the computer simpler.
For example, it may have larger keys or use colours and symbols to help users find what they need quickly. Some accessibility keyboards also have buttons that can be programmed for specific tasks, so users can do things like open applications or access frequently used functions with just one press. These keyboards help ensure that everyone, regardless of their abilities, can effectively interact with technology.
What is Keyboard Accessibility Testing?
WCAG Keyboard accessibility testing is a method used to check if a website or application can be easily used with just a keyboard. This is important for people who cannot use a mouse due to physical disabilities. During this testing, users will try to navigate through the site or app using only the keyboard. The goal is to see if all parts of the site, like menus, forms, and buttons, can be accessed easily. If users can move around without any problems and perform actions, it shows that the site is accessible. This ensures that everyone can use the website, no matter what their abilities are.
How to Test Keyboard Accessibility with Assisted Tests
Testing keyboard accessibility with assisted tests involves asking users who may have disabilities to interact with your website or application. Start by gathering a group of users that represent different abilities. Provide them with tasks to complete, such as filling out a form or navigating to a specific page, all while using only the keyboard. Observe how easily they can move around the site and if they encounter any difficulties. Encourage them to share their thoughts and any frustrations they experience. After the testing, review their feedback to identify areas for improvement. This process helps in making sure your website is user-friendly for everyone.
Actual process to test the keyboard accessibility of your website, begin by navigating through all interactive elements using only the keyboard. This includes links, buttons, form fields, and any other controls.
When testing keyboard accessibility, it’s essential to understand how to efficiently navigate your website using specific keys.
- TAB: The TAB key allows users to move forward through interactive elements in the order they appear on the page.
- SHIFT+TAB: Conversely, SHIFT+TAB enables users to navigate backward, giving them control over the direction of their movement.
- ENTER or RETURN: Pressing ENTER or RETURN activates the currently focused link or button.
- SPACEBAR: The SPACEBAR can be used to trigger buttons or toggle checkboxes.
- ARROW KEYS: The ARROW KEYS are useful for navigating through options in dropdown menus or sliders, enhancing overall navigation fluidity.
- ESCAPE: The ESCAPE is used to dismiss dialogs.
Understanding and utilizing these keys ensures a more accessible experience for keyboard users.
How Does a Keyboard Assisted Testing Tool Work?
A keyboard assisted testing tool helps check if a website or application can be used easily with just a keyboard. When you use the tool, it will mimic how a person who cannot use a mouse would navigate through the site.
The tool tests all the important elements, like links, buttons, and forms, to see if they can be accessed using keyboard shortcuts. It also checks if the site responds correctly when keys are pressed. By running these tests, developers can find out if there are any parts of the site that are hard to reach or use and make necessary changes to improve accessibility for everyone.
Why Do You Need Keyboard Accessibility Testing?
Keyboard accessibility testing is important because it ensures that everyone can use your website, especially those who cannot use a mouse. Many people rely on keyboards because of disabilities or other reasons.
By testing keyboard accessibility, you can find out if your site is easy to navigate for these users. If they have trouble using your site, they may become frustrated and leave. Making sure your website works well with just a keyboard helps create a better experience for all users, showing that you care about inclusion and accessibility.
Features of Keyboard Assisted Testing Tools
Keyboard assisted testing tools come with several key features that make them effective for checking website accessibility.
First, they can simulate keyboard navigation, allowing users to see how a person who only uses a keyboard would move through a site.
Second, these tools often include a feature to highlight interactive elements, such as buttons and forms, helping testers focus on what needs to be checked.
Third, many tools provide reports that show any accessibility issues encountered during testing, making it easier to track problems that need fixing.
Lastly, some tools can integrate with other testing platforms, helping developers create a comprehensive accessibility strategy.
Together, these features help ensure that websites are user-friendly for everyone, regardless of their needs.
Keyboard Accessibility Testing Test Cases
- Tab Navigation:
- Verify that all interactive elements (links, buttons, form fields) are reachable using the Tab key.
- Ensure the Tab key cycles through elements in a logical order, following the visual layout.
- Shift + Tab Navigation:
- Confirm that pressing Shift + Tab allows users to navigate back to the previous interactive element smoothly.
- Form Element Accessibility:
- Test each form element for focusability and ensure that pressing Enter submits the form or triggers the intended action.
- Check that all form fields have associated labels, making it clear for users what information is required.
- Activate Elements:
- Ensure buttons can be activated using the Spacebar or Enter key, and verify that any associated actions (like expanding a menu) work as intended.
- Arrow Key Navigation:
- Ensure users can navigate through dropdown menus, sliders, and other selectable elements using the arrow keys. The up and down arrows should move the selection up or down, while left and right arrows can be utilized in horizontal navigation scenarios.
- Verify that focus is clearly visible on the currently selected element when arrow keys are used, to enhance the user experience.
- Radio Button Accessibility:
- Test that users can select a radio button using the Tab key to navigate to the group and the arrow keys to select their preferred option. Ensure that upon pressing the Spacebar, the selected radio button is activated.
- Confirm that it is clear which radio button is selected at all times, whether by visual indication or through screen reader support, making it easier for users with disabilities to understand their choices.
- Skip Links:
- Verify the presence and functionality of “skip to content” links that allow users to bypass navigation menus and get to the main content quickly.
- Keyboard Shortcuts:
- Test any custom keyboard shortcuts to ensure they are intuitive and do not conflict with browser or assistive technology shortcuts.
- Focus Indicators:
- Ensure there are visible indicators (such as outlines or highlights) for focused elements, helping users identify which element is currently selected.
- Error Messaging:
- Confirm that error messages can be read via keyboard navigation and that they are clearly associated with the relevant input fields.
- Custom Widgets:
- Test any custom widgets (like dropdowns, modals, or carousels) to ensure they can be fully operated using a keyboard without requiring a mouse.
- Accessibility Documentation:
- Review any provided documentation for keyboard shortcuts or navigation tips to ensure they are clear and accessible to users.
