Visual Regression Testing Tool at Brighton and Hove city

Screenshot Comparison: VRT tools capture screenshots of web pages or UI components before and after changes are made. They then compare these screenshots pixel by pixel to detect any differences in layout, styling, or content.

Baseline Creation: VRT tools establish a baseline set of screenshots representing the expected appearance of the application or webpage. These baseline screenshots serve as a reference for future comparisons to ensure that visual changes are intentional and expected.

Automated Testing: VRT tools automate the process of capturing screenshots and comparing them, reducing the need for manual inspection and verification. This enables developers and QA teams to quickly identify visual regressions and address them before they impact the user experience.

Integration with CI/CD Pipelines: Many VRT tools integrate seamlessly with Continuous Integration/Continuous Deployment (CI/CD) pipelines, allowing visual regression tests to be run automatically as part of the software development lifecycle. This ensures that visual changes are detected early and consistently across different environments.

Selective Testing: VRT tools often provide the ability to selectively test specific components, pages, or UI elements, allowing developers and QA teams to focus their testing efforts where they are most needed.

Visual Diff Analysis: VRT tools highlight visual differences between screenshots, providing detailed insights into the nature and extent of the changes. This helps developers pinpoint the cause of visual regressions and take appropriate corrective actions.

Cross-Browser and Cross-Device Testing: Some VRT tools support testing across different browsers, devices, and screen resolutions, ensuring that visual consistency is maintained across various platforms and environments.

Version Control Integration: Many VRT tools integrate with version control systems such as Git, allowing teams to track changes to baseline screenshots over time and revert to previous versions if needed.

Automated Screenshots: VRT tools automatically capture screenshots of web pages or UI components before and after changes are made to the application.

Visual Comparison: These tools compare screenshots pixel by pixel to detect any visual differences between the baseline and the current version.

Baseline Management: VRT tools allow users to establish and manage baseline screenshots, which serve as a reference for comparison during subsequent tests.

Selective Testing: Users can choose specific pages, components, or UI elements to be included in the visual regression tests, focusing testing efforts where they are most needed.

Cross-Browser Testing: Some VRT tools support testing across different web browsers to ensure consistency in appearance and behavior.

Cross-Device Testing: These tools may also support testing across various devices and screen resolutions to ensure responsiveness and visual consistency across different platforms.

Integration with CI/CD Pipelines: VRT tools seamlessly integrate with Continuous Integration/Continuous Deployment (CI/CD) pipelines, allowing tests to be automated and run as part of the deployment process.

Version Control Integration: Many VRT tools integrate with version control systems, enabling teams to track changes to baseline screenshots over time and collaborate effectively.
