How do I start the snapshot manager in Claude Code?

You can trigger the skill by using the /snapshot-manager or /sm commands, or by asking Claude to analyze snapshot failures.

Can I update specific snapshots instead of the whole suite?

Yes, the skill is designed for selective updates, allowing you to update only the snapshots that reflect intentional changes.

How does it help with regression testing?

It provides side-by-side diff analysis to help you verify if a change is expected or if a bug has caused an unintentional UI regression.

Which testing frameworks does this skill support?

This skill supports major JavaScript testing frameworks including Jest, Vitest, Playwright, and Storybook.

セキュリティとテスト

Manages and updates snapshot tests by analyzing diffs and distinguishing intentional UI changes from regressions.

概要

The Snapshot Test Manager skill empowers developers to maintain high-quality UI test suites across popular frameworks like Jest, Vitest, and Playwright. By providing intelligent diff analysis and selective update capabilities, it helps Claude identify whether snapshot failures are expected results of code changes or genuine regressions. This ensures that snapshot integrity is maintained without resorting to blind updates, making it an essential tool for visual and structural testing workflows.
