3 Ways to Test Your WordPress Website for Visual Changes

Keeping your WordPress website visually consistent and error-free is crucial for maintaining a professional appearance and ensuring a smooth user experience. Whether you’re making minor tweaks or significant updates, testing for visual changes helps you catch issues before they affect your audience. Let’s dive into three effective methods for testing visual changes on your WordPress site.

Method 1: Manual Testing

Overview of Manual Testing

Manual testing involves personally reviewing your website to identify any visual discrepancies. This method relies on your keen eye and attention to detail.

Steps to Perform Manual Testing

Preparing for Manual Testing

Before you begin, ensure you have a checklist of elements to review, such as fonts, colors, layout, and images. Open your website in multiple browsers and devices to account for different rendering.

Executing the Test

Navigate through your website, page by page, comparing each element against your baseline design. Take notes of any discrepancies and capture screenshots for reference.

Pros and Cons of Manual Testing

Manual testing is straightforward and doesn’t require technical skills, making it accessible. However, it can be time-consuming and prone to human error, especially on large websites.

Method 2: Using Browser Extensions

Overview of Browser Extensions for Visual Testing

Browser extensions can automate parts of the visual testing process, alerting you to changes without extensive manual intervention.


Visualping monitors webpages for changes and sends notifications when differences are detected. It’s easy to set up and customize for specific elements on your site.

Page Monitor

Page Monitor is another extension that tracks changes and provides updates. It’s less feature-rich than Visualping but still useful for simple monitoring tasks.

How to Use Browser Extensions

Installing the Extension

Install your chosen extension from the browser’s add-on store. Most extensions are free or have a free tier.

Configuring Settings

Set up the extension to monitor specific pages or elements. Configure the frequency of checks and the type of changes to track, such as text or visual changes.

Pros and Cons of Browser Extensions

Browser extensions are user-friendly and automate the monitoring process. However, they may not catch all types of changes and often require manual verification of detected issues.

Method 3: Automated Testing Tools

Overview of Automated Testing Tools

Automated testing tools offer comprehensive solutions for detecting visual changes. They are more powerful and versatile than browser extensions, suitable for larger or more complex sites.


Selenium is a robust tool for automating web browsers. It’s highly customizable, making it ideal for extensive testing scenarios.


Applitools specializes in visual testing, using AI to detect subtle differences between baseline and test images. It’s particularly effective for regression testing.

How to Use Automated Testing Tools

Setting Up the Tool

Install and configure the tool according to the documentation. This often involves setting up a test environment and creating scripts to run the tests.

Running Automated Tests

Execute the tests and review the results. Automated tools typically generate detailed reports highlighting the differences detected.

Pros and Cons of Automated Testing Tools

Automated tools are thorough and efficient, capable of handling complex testing requirements. However, they can be expensive and require technical expertise to set up and maintain.


Testing for visual changes on your WordPress site is essential to maintain a polished and consistent appearance. Manual testing, browser extensions, and automated tools each offer unique benefits and challenges. By understanding these methods, you can choose the one that best fits your needs and resources.
