# Your First Workflow Automation: End-to-End Tester

> Automatically verify PRs with a real-world end-to-end testing pass before merge using the End-to-End Tester Expert.

## End-to-End Tester

Install it during onboarding from the **Pick Experts** step. After that it watches for two things: a fresh PR (opened or moved out of draft) and a Slack message that mentions `@Augment` with a PR link.

* **Best for**: Changes that need a real-world verification pass before merge — feature flows, regressions, integration points, or risky PRs where you want evidence from a running app or service.
* **How to use**: Give the End-to-End Tester a GitHub PR URL. It reviews the PR context, chooses an appropriate e2e/integration check, runs the verification, and posts a concise pass/fail/unable-to-verify result directly on the PR.
