There are many accessibility testing tools available, and we recommend using either WAVE or Lighthouse. Which one you use is a matter of preference.
Tips to remember:
To install WAVE, visit the WAVE webpage and choose the browser extension you would like to use. After installation, the extension will appear to the right of your browser address bar.
Click on the WAVE icon to the right of your browser address bar. You will see this WAVE interface.

Click the icon again or refresh the page to remove the WAVE interface.
Lighthouse is a Chrome browser extension that runs audits for accessibility and other performance-related tasks.
To install Lighthouse, visit the Lighthouse webpage using Google Chrome and click on Install Extension.
Click on the Lighthouse icon in your toolbar, and select Generate Report. Once the report is generated, select the Accessibility tab to see the test results.
