Testing with Continuum Explorer

Continuum Explorer is a Chrome extension that allows developers to test their UI code for accessibility as they are building screens. Learn more about Continuum Explorer and how to download and install it in the Continuum Explorer Overview article.

Ideal Testing Scenario for Continuum Explorer

Continuum Explorer works best in testing scenarios where a developer is building UI and validating it locally before checking in the code. This scenario might proceed as follows: 

  1. The developer creates a new page and saves it locally. 
  2. The developer builds the application and loads the new page in the browser window. 
  3. The developer reviews the page for any issues, then returns to their IDE to fix the issues. 
  4. When the issues are fixed, the developer saves the fixes, rebuilds the application, and reloads the page in the browser window to re-inspect the page visually. 

Testing for Accessibility with Continuum Explorer

In the above testing scenario Continuum Explorer can be used during the the visual inspection stage. To do so, perform the following steps: 

  1. Open the page that is in development within the browser window (at the moment, this extension is available in Chrome only). 
  2. Launch Continuum Explorer and make sure the page to be tested is loaded in the active tab in the main browser window. Continuum Explorer will display a message indicating that the active tab has changed from its last use, along with a button to test the page. If you have moved from the original page, a "Go Back" button will also be displayed to allow you to navigate back to the original tab being tested.

  3. Select the "Test This Page" button to test the active page. Violation instances will be displayed in the Continuum Explorer window. 
  4. Select a violation to view the details for the violation, including recommended remediation steps.

    The selected violation instance will also be highlighted in the main browser window.
  5. In your IDE, make changes to the source code to fix accessibility issues highlighted by Continuum Explorer. Save and rebuild. 
  6. Reload the page in the main browser window. 
  7. Continuum Explorer will now indicate that the page has been updated and prompt you to retest. 
  8. When the "Test This Page" button is selected, the page will be retested and Continuum Explorer will display an updated list of violations.
