Regression testing ensures that code changes haven’t disrupted existing software functionalities. Similarly, visual regression testing verifies that these changes haven’t altered the software’s visual appearance. This type of testing is crucial for identifying visual defects such as style inconsistencies, alignment issues, and font discrepancies. Common visual errors include overlapping elements, missing or hidden components, and elements not correctly displayed on-screen.
Imagine booking a flight and, after entering all your details, you reach the checkout page only to find that the checkout button is hidden behind the cancel button, preventing you from completing your booking. Such visual glitches can significantly impact user experience and deter customers from returning to the website.
This highlights the importance of visual regression testing in maintaining a seamless and error-free user interface.
