MainWP – Regression Testing

MainWP – Regression Testing is a WordPress add-on designed to monitor and detect changes across multiple websites managed through the MainWP dashboard. It focuses on identifying structural and content modifications that may occur after plugin updates, theme changes, or manual edits. By comparing snapshots of a site’s HTML over time, the plugin helps users detect issues early and maintain site stability.

The add-on operates within a centralized management environment, allowing users to monitor all connected child sites without affecting their performance. It analyzes rendered HTML rather than relying solely on visual comparisons, which helps detect meaningful changes such as code alterations, layout shifts, or missing elements.

Users can configure automated scans to run on a schedule or trigger them after updates. The plugin evaluates differences between scans and assigns a change percentage, making it easier to identify significant modifications. Email notifications can alert users when changes exceed a defined threshold, enabling quick response to potential issues.

The plugin also provides detailed comparison tools, including raw HTML diff views, rendered before-and-after previews, and tracking of CSS and JavaScript changes. These features support troubleshooting and help maintain consistency across multiple WordPress sites.
