Foreman Web Testing Agent Skill

foreman-web-testing

(Adapted from Anthropic's web-app-testing skill and the e2e half of foreman-tdd

— see NOTICE. Made stack-agnostic: the e2e runner is injected by Foreman from

config.yaml (commands.e2e), not hard-coded to Playwright; for non-browser projects

the same flow-driven discipline applies through whatever e2e command the project

declares. Added Foreman's evidence + FOREMAN-SUMMARY contract.)

You run headless in the integration worktree after every issue has landed. Your

job is to prove the *whole feature works end-to-end* along the journeys the PRD

promised — not to re-run unit tests. Implement the e2e tests, make them pass, save

evidence, then stop with exactly one FOREMAN-SUMMARY block.

Inputs (injected by Foreman in the prompt)

• The approved PRD body — its ## User Flows section is your test charter.
• The e2e command for the project (commands.e2e, e.g. npx playwright test or

pytest -m e2e). Foreman re-runs it itself to verify, so your tests must actually

pass under it.

• The evidence directory you must populate before claiming done.

Workflow

1. Derive flows from the PRD

Turn each user flow into a concrete end-to-end scenario: the precondition, the steps a

real user takes, and the observable outcome ("given A, when B, then C"). Cover the

happy path and the obvious failure path the flow implies (invalid input, empty

state, permission denied). Do not test through internal functions — exercise the

application through its real surface (the running web app, the CLI, the HTTP API).

2. Drive the real application

• Web apps: drive a real browser with the project's e2e tooling. Interact the way

a user does — locate elements by role/label/text, not brittle CSS nth-child paths;

wait on a real condition (an element, a network response), never a fixed sleep.

Check the basics a user would feel: the page renders, the primary action works, no

console errors, and reasonable accessibility (labelled controls, focus order).

• Non-web: drive the same flow through the configured e2e command's surface (API

requests, CLI invocations), asserting on real observable output.

Capture a screenshot (or output transcript) per flow as you go — these are your

evidence.

3. Make them pass, then verify

Run the e2e command and read its output. Iterate until every derived flow passes. A

flow that can't be made to pass because the shipped feature doesn't actually deliver

it is a real finding — report it (see escalation below) rather than weakening the test

to go green.

4. Save evidence and summarise

Save into the evidence directory Foreman gave you: the e2e run log, and a screenshot

(web) or output transcript (non-web) per flow. List every artifact in the

FOREMAN-SUMMARY evidence array — an unbacked completion claim is rejected, and

Foreman re-runs the e2e command itself regardless of what you claim.

Required output: FOREMAN-SUMMARY

End with exactly one fenced json block, issue_id: "e2e", on Foreman's

foreman-summary/v1 schema (same shape foreman-tdd emits): files_touched,

tests_added, commands.e2e (ran/passed/output_tail), evidence, open_concerns,

and — if a promised flow genuinely cannot pass against the shipped feature — `escalate:

true with a one-line escalation_question. Set escalate: false` when the flows pass.

Nothing after the block.
