How to Test Your Website With NVDA and JAWS
Testing your website for accessibility is crucial to ensure that all users, including those who rely on screen readers, can navigate and interact with your content effectively. NVDA (NonVisual Desktop Access) and JAWS (Job Access With Speech) are popular screen readers that assist visually impaired users in accessing digital information. This article outlines how to test your website using both NVDA and JAWS.
Getting Started with NVDA
To begin testing your website with NVDA, follow these steps:
- Download and Install NVDA: Visit the official NVDA website and download the software. It is free and compatible with Windows.
- Launch NVDA: Once installed, open NVDA and your web browser of choice. NVDA will automatically read out text on the webpage as you navigate.
- Navigate Your Website: Use the arrow keys to move through your content. Pay attention to how NVDA reads headings, links, and form fields. This can help you identify areas that may be confusing for users.
- Check for Keyboard Navigation: Ensure that all interactive elements can be accessed via the keyboard. Use the Tab key to cycle through links and form fields.
Key Features to Test with NVDA
While using NVDA, focus on the following aspects:
- Headings Structure: Ensure that headings are properly nested and follow a logical order (e.g., H1, H2, H3).
- Alternative Text: Check that all images have appropriate alt attributes, allowing NVDA to convey information effectively.
- Dynamic Content: Test how NVDA handles live regions, alerts, or any content that updates dynamically.
Testing with JAWS
JAWS is a powerful screen reader with additional features suited for advanced users. To test your site with JAWS, follow these steps:
- Install JAWS: Visit the Freedom Scientific website to download the JAWS software trial or purchase a license.
- Open JAWS: Launch JAWS and your web browser. Similar to NVDA, it will start reading the text content of the webpage.
- Utilize Quick Keys: JAWS offers specific keyboard shortcuts to streamline navigation. For instance, use H to jump through headings and Tab to move between links and form controls.
- Check List of Links: Press Insert + F7 to open a list of links on the page. This feature helps identify any missing links or proper labeling.
Important Features to Test with JAWS
When using JAWS, consider examining the following:
- Forms and Labels: Ensure that form elements have associated labels for clarity and usability.
- Read All Content: JAWS can read the entire page by using the Down Arrow key. Confirm that the reading flow makes sense and is easy to follow.
- Accessibility Features: Test using the JAWS virtual cursor to confirm that all interactive elements are easily accessible.
Running Effective Accessibility Tests
Combine the information gathered from both NVDA and JAWS to conduct a comprehensive accessibility evaluation of your website. Document any issues you encounter and prioritize fixing them to enhance your site's usability for all users.
In summary, testing your website with NVDA and JAWS not only boosts accessibility but also improves user experience. Regularly conducting these tests ensures your website remains compliant with accessibility standards and caters to a diverse audience.
