MainWP Regression Testing Extension

Updates to WordPress core, themes, or plugins can change how a site looks. This extension captures before-and-after screenshots to help site managers identify visual differences without checking every page by eye. Side-by-side comparisons and highlighted changes make it easier to review what changed after an update.

The plugin works with the MainWP dashboard, where webmasters and agencies can manage regression testing across multiple WordPress sites. Testing can be scheduled to run after updates, and screenshot resolution and comparison sensitivity can be adjusted. Reports and notifications provide details about detected changes for further review.
