Capabilities
What can you do with Webapp Testing?
Verify the running interface instead of reasoning from source alone.
Use this plugin when a local web application must be exercised in a browser, visually inspected, debugged, or checked across a user flow.
- Start and stop local application servers reliably.
- Inspect page structure before choosing selectors.
- Automate user flows with Playwright.
- Capture screenshots and browser console output.
- Test failure states without modifying production data.
Reconnaissance before action
The workflow reads the page and discovers elements before clicking, reducing brittle guesses and accidental interaction.
Keep tests contained
Local servers, test accounts, screenshots, logs, and explicit cleanup make browser effects easier to review and control.
Practical workflow
From running app to reproducible browser evidence
Pass 01 / Observe
Start and inspect the application
Launch the required server, open the page, collect structure and logs, and identify stable interaction targets.
Pass 02 / Exercise
Run and capture the flow
Perform the user journey, record screenshots and console errors, verify outcomes, and stop managed servers.

What this plugin does
Webapp Testing provides a Playwright-based workflow for local web applications. It manages server lifecycle, inspects pages before acting, automates user flows, captures screenshots, and records browser console output.
Practical workflow
Start the local application with the supplied helper, open the target page, and inspect its structure and logs. Choose stable interaction targets, exercise the user journey, record evidence, verify outcomes, and stop managed servers.
Safe test boundaries
Use local or isolated test environments and test accounts. Do not automate real purchases, messages, account deletion, or production changes. Review scripts before execution and clean up test data and background processes.
