Catching visual regressions between deploys with two API calls

说明与用途

自动截图捕获和监控在部署后检测视觉回归，减少发布后发现的 UI 问题。

问题

Visual changes can slip through code and unit tests, causing broken UI elements to be noticed only after deployment.

结果

Visual regressions are detected automatically, reducing post‑deploy fixes and improving UI reliability.

工作流

• 1. Trigger CI job after deploy.
• 2. Use Screenshot API to capture full page or element with curl and store as artifact.
• 3. Optionally create a monitor via API to watch the page at intervals.
• 4. Monitor compares new capture to previous and posts diff to webhook if threshold exceeded.
• 5. Integrate webhook with Slack, ticketing, or automation workflows.

证据

Unit and end‑to‑end tests tell you the logic works. They rarely tell you the page still looks right

来源

You can take a screenshot of the page from your CI job with one request and store it as a build artifact

If you want to be told when a page changes visually between deploys, create a monitor and point it at any webhook you control

来源

The threshold is a flat percentage of changed pixels across the whole page. A rotating ad or a live timestamp counts toward it
