From the developer

Bleech's own description of VRTs, lightly tidied.

Find issues before others do – every time. With automatic screenshots, daily comparisons, and instant tests after WordPress and plugin updates. Select the pages of your choice for continuous monitoring. The plugin immediately notifies you of any visual changes it detects.

Please note: The website must be publicly accessible in order to set up and run the tests. Password protection or any kind of firewall might prevent the plugin from working correctly.

Your strategy to spot unwanted changes

How do you check your website after updates and code changes? Do you manually go through pages, or do you just cross your fingers, hoping everything will be okay? Visual regression testing provides a better way to spot issues and detect visual changes. The VRTs plugin automates testing for you with a click of a button.

  1. Activate tests for any page or post: Upon activation, a reference screenshot is taken. This will be renewed when a post is saved or updated.
  2. VRTs monitors your pages: Every day, VRTs captures and compares screenshots of your selected pages. Upgrade to Pro to automate tests for WordPress updates, integrate deployment pipelines via API, and run manual tests on demand.
  3. Receive instant alerts: If a change is detected between the snapshot and the comparison screenshot, the plugin will notify you via email.
  4. Review changes: The difference view makes it easy to spot changes, while the comparison slider lets you inspect the details.
  5. Hide elements: Prevent false positives by excluding dynamic elements, ads, and animations from snapshots.
