E2e Cucumber Playwright

---
name: e2e-cucumber-playwright
description: Write, update, or review Dify end-to-end tests under `e2e/` that use Cucumber, Gherkin, and Playwright. Use when the task involves `.feature` files, `features/step-definitions/`, `features/support/`, `DifyWorld`, scenario tags, locator/assertion choices, or E2E testing best practices for this repository.

# Dify E2E Cucumber + Playwright

Use this skill for Dify's repository-level E2E suite in `e2e/`. Use [`e2e/AGENTS.md`](../../../e2e/AGENTS.md) as the canonical guide for local architecture and conventions, then apply Playwright/Cucumber best practices only where they fit the current suite.

## Scope

- Use this skill for `.feature` files, Cucumber step definitions, `DifyWorld`, hooks, tags, and E2E review work under `e2e/`.
- Do not use this skill for Vitest or React Testing Library work under `web/`; use `frontend-testing` instead.
- Do not use this skill for backend test or API review tasks under `api/`.

## Read Order

1. Read [`e2e/AGENTS.md`](../../../e2e/AGENTS.md) first.
2. Read only the files directly involved in the task:
   - target `.feature` files under `e2e/features/`
   - related step files under `e2e/features/step-definitions/`
   - `e2e/features/support/hooks.ts` and `e2e/features/support/world.ts` when session lifecycle or shared state matters
   - `e2e/scripts/run-cucumber.ts` and `e2e/cucumber.config.ts` when tags or execution flow matter
3. Read [`references/playwright-best-practices.md`](references/playwright-best-practices.md) only when locator, assertion, isolation, or waiting choices are involved.
4. Read [`references/cucumber-best-practices.md`](references/cucumber-best-practices.md) only when scenario wording, step granularity, tags, or expression design are involved.
5. Re-check official docs with Context7 before introducing a new Playwright or Cucumber pattern.

## Local Rules

- `e2e/` uses Cucumber for scenarios and Playwright as the browser layer.
- `DifyWorld` is the per-scenario context object. Type `this` as `DifyWorld` and use `async function`, not arrow functions.
- Keep glue organized by capability under `e2e/features/step-definitions/`; use `common/` only for broadly reusable steps.
- Browser session behavior comes from `features/support/hooks.ts`:
  - default: authenticated session with shared storage state
  - `@unauthenticated`: clean browser context
  - `@authenticated`: readability/selective-run tag only unless implementation changes
  - `@fresh`: only for `e2e:full*` flows
- Do not import Playwright Test runner patterns that bypass the current Cucumber + `DifyWorld` architecture unless the task is explicitly about changing that architecture.

## Workflow

1. Rebuild local context.
   - Inspect the target feature area.
   - Reuse an existing step when wording and behavior already match.
   - Add a new step only for a genuinely new user action or assertion.
   - Keep edits close to the current capability folder unless the step is broadly reusable.
2. Write behavior-first scenarios.
   - Describe user-observable behavior, not DOM mechanics.
   - Keep each scenario focused on one workflow or outcome.
   - Keep scenarios independent and re-runnable.
3. Write step definitions in the local style.
   - Keep one step to one user-visible action or one assertion.
   - Prefer Cucumber Expressions such as `{string}` and `{int}`.
   - Scope locators to stable containers when the page has repeated elements.
   - Avoid page-object layers or extra helper abstractions unless repeated complexity clearly justifies them.
4. Use Playwright in the local style.
   - Prefer user-facing locators: `getByRole`, `getByLabel`, `getByPlaceholder`, `getByText`, then `getByTestId` for explicit contracts.
   - Use web-first `expect(...)` assertions.
   - Do not use `waitForTimeout`, manual polling, or raw visibility checks when a locator action or retrying assertion already expresses the behavior.
5. Validate narrowly.
   - Run the narrowest tagged scenario or flow that exercises the change.
   - Run `pnpm -C e2e check`.
   - Broaden verification only when the change affects hooks, tags, setup, or shared step semantics.

## Review Checklist

- Does the scenario describe behavior rather than implementation?
- Does it fit the current session model, tags, and `DifyWorld` usage?
- Should an existing step be reused instead of adding a new one?
- Are locators user-facing and assertions web-first?
- Does the change introduce hidden coupling across scenarios, tags, or instance state?
- Does it document or implement behavior that differs from the real hooks or configuration?

Lead findings with correctness, flake risk, and architecture drift.
