Web Application Automated Testing

Problem

Local web apps often need interaction checks while a backend, frontend, and static pages are all running. Manually starting services, waiting for loads, and hunting selectors adds avoidable fragility: missed waits and service-management logic can leak into test code.

How It Works

• Treat the helper as a black box: inspect usage first with scripts/with_server.py --help, then use it to start one or more services while test scripts contain only playwright logic.
• Probe before acting: inspect the rendered DOM, choose text=, role=, CSS, or ID selectors from the result, then perform clicks, input, and assertions.
• Use the sync Python style: prefer sync_playwright(), pair it with page.wait_for_load_state('networkidle') and page.wait_for_selector(), and call browser.close() before finishing.

Boundaries And Notes

This skill targets local web app automation tests, including button, link, and input discovery, static HTML interaction, and console log capture. Dynamic apps should wait for a stable state before DOM checks; do not assume the helper replaces real backend validation.
