If you’ve ever changed your website, no matter how small, you know that it can sometimes have unintended consequences. Maybe a button that used to be blue is now green, or a photo that used to appear on your homepage has disappeared. Sound familiar?
These types of changes are relatively minor, but they can still disrupt the user experience and cause headaches for you and your team. That’s where regression testing comes in.
Regression testing is the process of retesting a website or application after a change has been made to ensure that the change did not break any existing functionality. In other words, it’s a way to catch bugs before they cause major problems.
How to Perform Regression Testing on your Website
To ensure that your website is functioning properly, it is important to perform regression testing regularly. This type of testing involves retesting the website after changes have been made to the code to ensure that the changes have not introduced any new bugs. This will ensure that you have a high-quality website with a good user experience. How can you perform Regression Testing, then?
1. Use a Web Crawler
There are several different ways to perform regression testing, but one common approach is to use a web crawler. This type of software simulates the actions of a real user, visiting each page of the website and checking for errors.
2. Use Web Testing Tools
Another approach is using web testing tools, which can be a great way to catch errors on your website before posting it live. For example, Preflight is an easy-to-use tool that reports any problems with the code or content of sites in minutes instead of hours. Whichever method you choose, regression testing is an essential part of maintaining a healthy website.

Types of Changes That Require Regression Testing
Almost any type of change to your website can potentially break something, so it’s important to always test after making any changes, no matter how small. Some common types of changes that require regression testing include:
1. Code Changes
Refactoring code, adding new features or making changes to existing features. It is a good practice to run regression tests whenever code is changed.
2. Design Changes
Changing the layout or styling of your website. Even something as minor as changing a button’s color can impact your site’s usability, so it’s important to test after making any design changes.

3. Content Changes
Updating text, adding new images or videos, or changing the location of existing content. Like design changes, content changes can also impact your site’s usability, so it’s important to test after making any updates.
4. Configuration Changes
Changing server settings or updating third-party software such as plugins or modules. These changes can sometimes introduce unexpected bugs, so regression testing is especially important after making any configuration changes.
As you can see, regression testing is an important part of maintaining a high-quality website. Any time a change is made to your codebase—no matter how small—regression tests should be run to ensure that the change did not break any existing functionality. By catching bugs before they cause major problems, regression testing helps you keep your website running smoothly and provides a better user experience.
