FAQPage Schema
How do I automate visual reviews for UI regressions after deployment?

Automated visual reviews register tokens and start runs via the MCP server to check web UIs for regressions. You get screenshots and assertion artifacts detailing any unintended visual changes caused by recent code updates.

What is the best way to retrieve screenshots and artifacts from a visual review run?

To retrieve visual review artifacts, the process polls the MCP server for run results and fetches generated reports and screenshots. This automated artifact retrieval provides detailed visual feedback on UI inconsistencies and bugs.

Does visual review automation require an MCP server to run?

Yes, automated visual review requires an active MCP server. The process executes by interacting with the server at http://127.0.0.1:4040 to register tokens, start review runs, and poll for completion.

Can I use this visual review process to catch UI inconsistencies before they reach users?

Yes, you can perform a comprehensive visual review against specified web URLs to catch UI inconsistencies. The process fetches detailed reports and artifacts generated during the review to identify bugs before users see them.

How does the visual review process actually execute against a web application?

The visual review process executes by automating interactions with the MCP server. It registers tokens, starts review runs against target web URLs, polls for results, and retrieves artifacts like screenshots and assertions.

When do I need to run an automated visual review of my web UI?

You need an automated visual review when deploying new features to a web application. It ensures that code changes do not introduce unintended visual regressions, catching UI inconsistencies and bugs before they reach users.
