SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Coordinated end-to-end testing of local web applications requires spinning up multiple services, managing their lifecycles, and collecting evidence. This skill provides a hardened, repeatable pattern for driving Playwright against locally running frontend and backend services, with safe server orchestration and teardown. It also emphasizes robust error handling, observability (console logs and screenshots), and a reproducible workflow for QA and development teams.

Core Features & Use Cases

  • End-to-end web app testing against locally running services using Playwright in Python.
  • Agency-hardened server orchestration with scripts/with_server.py to start, wait for readiness, and cleanly tear down multiple servers.
  • Reconnaissance-then-action pattern to stabilize element references by snapshotting and re-sensing after navigation; captures console logs and screenshots as evidence.
  • Use cases include validating multi-service local apps, debugging UI regressions, and automating repetitive QA checks during feature development.

Quick Start

Run your Playwright-based test script against the locally started web app using the agency-hardened with_server harness.

FAQPage Schema
How do I run Playwright tests against multiple locally running web servers?

To run Playwright tests against multiple local web servers, you can use a hardened server runner to coordinate startup, wait for network idle, and cleanly tear down services. This ensures reliable, repeatable end-to-end validation of local web apps.

What is the best way to capture console logs and screenshots during local web app testing?

The best way to capture console logs and screenshots during local web app testing is using a reconnaissance-then-action pattern. This approach snapshots and re-senses elements after navigation to stabilize references while collecting evidence.

How do I stabilize Playwright element references that break after page navigation?

To stabilize Playwright element references after navigation, apply a reconnaissance-then-action pattern that snapshots and re-senses elements. This hardened approach prevents reference errors during automated UI regression checks.

Can I use Python Playwright to automate end-to-end testing for local multi-service apps?

Yes, you can use Python Playwright to automate end-to-end testing for local multi-service apps. This approach requires Playwright in Python and uses a hardened server runner to manage service lifecycles and collect testing evidence.

Why do my local web app end-to-end tests fail during server startup and teardown?

Local web app end-to-end tests often fail during startup and teardown due to uncoordinated service lifecycles. A hardened server runner solves this by managing server startup, waiting for readiness, and ensuring clean teardown with robust error handling.

How do I automate repetitive QA checks for multi-server local web apps?

You can automate repetitive QA checks for multi-server local web apps by driving local Playwright scripts against locally running services. This provides a reproducible workflow with safe server orchestration and clear evidence collection.
