**Ensuring Quality Web Applications with Visual Regression Testing**

Visual regression testing is a crucial aspect of web application quality control. It involves comparing screenshots before and after changes to identify any visual differences that may indicate unexpected behavior. This approach ensures the consistency and user experience of web applications, catching inconsistencies in layout, color, font, or other visual elements.

To implement visual regression testing with Playwright, follow these steps: capture baseline screenshots, compare new screenshots, and analyze differences. ResembleJS or a chosen visual comparison library can be used to compare images. This approach reduces manual testing effort, increases test coverage, and enhances user satisfaction.

**Challenges and Considerations**

While visual regression testing is a valuable tool, it also comes with potential issues such as false positives, performance problems, integration challenges, test data sensitivity, and scalability concerns.
