Webapp Tester
Turn a critical browser journey into step-level Playwright evidence: what passed, what failed, what the browser logged, and where to investigate next.
What it tests
- Login, signup, form, checkout, and account flows from the user's point of view.
- Desktop plus iPhone- and Android-like layouts for overflow and hidden actions.
- Visible outcomes with retrying assertions instead of brittle timing sleeps.
- Console errors and page exceptions that a screenshot alone cannot explain.
- Stable surfaces with screenshots or visual comparisons when a baseline exists.
The result is a focused release record, not a vague “looks good”: tested URL, browser and device coverage, pass/fail by step, console evidence, artifact paths, and a likely fix location.
A representative run
Request: “Test signup, the first-run dashboard, and the upgrade checkout in staging. Do not complete a real charge.”
- passCreate an account.
- failDashboard loops to onboarding after profile save.
- log
POST /api/profile 409; trace saved.
The example shows the evidence shape. It is not a promise that every app exposes the same routes, devices, or failure.
How the workflow stays bounded
- Inspect the existing framework, package manager, Playwright configuration, and start command before adding files.
- Name the user journey and the observable result for each step.
- Run the narrowest useful test first, then add device or browser coverage.
- Use sandbox payment details, disposable accounts, and explicit approval for any production mutation.
- Keep screenshots, videos, traces, and saved auth state inside named test-output folders; never commit real cookies.
What it does not prove
A passing run covers only the journeys and assertions that executed. Webapp Tester does not certify security, accessibility, performance, every browser, or every business rule. Third-party checkout and identity pages can also change independently; test the handoff you control and use provider sandboxes for the external step.
Build the browser-test plan first
The web-app pre-launch testing guide shows how to select the first journeys, protect test credentials, use resilient locators and assertions, collect traces, and interpret what a green run actually proves.
Questions
What does Webapp Tester do?
It generates or adapts focused Playwright tests for important browser journeys, runs them in real browser contexts, and reports each user step with console errors, screenshots, traces, and likely fix locations.
What does Webapp Tester need to run?
It needs a reachable local, staging, or approved remote URL, a coding agent that reads SKILL.md, and Playwright in the target project or permission to add it. Authenticated flows also need disposable test credentials or an approved saved test state.
Will it charge cards or change production data?
Not without approval. The workflow requires test cards, sandbox credentials, and disposable accounts, and it asks before testing production paths that charge, send email, publish, or mutate real data.
How does it handle login state?
It prefers a Playwright setup project or storage-state file so login is not repeated in every test. Saved auth state may contain sensitive cookies and must stay in a gitignored test folder.
Does a passing Webapp Tester run prove the app is ready?
No. It proves only the named browser journeys, viewports, and assertions that ran. It does not replace security review, load testing, accessibility testing, or manual checks for untested business rules.
