VRTs – Visual Regression Tests

VRTs – Visual Regression Tests is a plugin to test your website for unwanted visual changes. The plugin runs automatic daily tests for chosen pages and posts. The tool creates daily comparison screenshots and compares them with a reference snapshot. If there is a difference between the screenshots, you’ll be automatically notified via email. Use three comparison modes to spot the differences easily.

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 usually check your website after updates and code changes? Do you go manually through all pages or do you just hope everything will run ok? Visual regression testing provides you a method that helps you find errors and visual abnormalities. The VRTs plugin gives you an environment to automate your process.

1. Activate daily 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. Receive instant alerts: If a change is detected between the snapshot and the comparison screenshot, the plugin will create an alert and notify you via email. The daily test will be paused, until the alert is resolved.
3. Compare two screenshots: Detect differences between the two snapshots with the difference, split screen or side-by-side view.
4. Exclude elements: Prevent false positives by excluding dynamic elements, ads and animations from snapshots.
5. Resolve tests: After fixing an issue, mark the alert as resolved. A new snapshot will be generated and the test will start running again.
