Verification Harnesses for Agentic UI Changes
AI coding tools are fast at editing code but blind to whether the UI actually behaves after the change. This course teaches you to use Playwright as a verification and observability layer so an agent (or you) can prove outcomes, detect regressions, and generate high-signal evidence from the running app. You’ll build a complete agent verification harness: deterministic tests that encode acceptance criteria, an evidence pipeline that emits traces, screenshots, logs, and structured failure summaries, and a controlled UI probe tool with guardrails and safe defaults. The workflow is model-agnostic and editor-agnostic, centered on Node.js and TypeScript, and ends with a capstone that runs in CI with artifacts that make failures explainable.
What You Will Master
The Senior Engineer Toolkit
Translate agent requirements into Playwright verification structures that prove UI behavior and catch regressions.
Build deterministic test state with fixtures, boundaries, and mocks that keep runs reliable across environments.
Produce failure dossiers with traces, screenshots, logs, and DOM snapshots plus machine-readable summaries for fast triage.
Expose Playwright as a minimal, safe agent tool surface with guardrails, allowlists, and auditability.
Ship a CI-ready verification harness with artifact storage patterns that work for humans and agents.
Prerequisites
Comfortable building production frontend apps with a modern framework and Node.js tooling.
Familiar with TypeScript and basic async patterns.
Have run or written at least one Playwright test before.
Experience with Git workflows and pull requests.
Prior use of an AI coding tool for day-to-day development.
