Fictional signup-form example with three DOM checks for empty input, signup success and reset; an illustrative test report.
Project screenshotsAbout this Skill
Use Playwright to inspect local web apps, exercise frontend flows and capture screenshots and logs. Python or Node.js Playwright, installed browser binaries and a running local application.
Why we picked it
Useful for checking a local web application through a real browser. It pairs Playwright scripts with a reconnaissance-first approach, especially when rendered DOM and load timing matter.
What it helps with
- Test a form's user journey.
- Inspect a dynamically rendered interface.
- Capture screenshots while debugging.
How this skill works
1. Start or connect to the local application
Start or connect to the local app, then inspect the rendered page before choosing selectors.
2. Inspect the DOM before selecting actions
Use Playwright to exercise user actions, collect screenshots and inspect browser behavior.
3. Assert behavior and capture browser evidence
Assert the expected results and investigate failures with the observed DOM and logs.
