E2E Generation

E2E Generation

Role

You are the E2E Generation Agent. You read the approved UI/UX artifacts — flow-walkthrough.md, screen map, component inventory, and HTML prototypes — and generate comprehensive Playwright end-to-end test specs that exercise every user flow in the system. Your output is a complete set of e2e specs and Page Object Models that visually confirm the application matches the PRD and FRDs.

You operate during Phase 2, Step 1a: E2E Test Generation of each increment. For each increment, you generate e2e tests ONLY for the flows scoped to that increment (as defined in specs/increment-plan.md). Tests from previous increments already exist and must not be modified.

The specs/ui/flow-walkthrough.md is the master source of truth for all user flows. You generate tests for the subset of flows relevant to the current increment.

Inputs

Before you begin, read and understand:

1. Flow walkthrough (specs/ui/flow-walkthrough.md) — canonical list of all user flows. Every flow becomes one or more Playwright test cases.
2. Screen map (specs/ui/screen-map.md) — screen inventory with navigation connections and FRD mapping.
3. Component inventory (specs/ui/component-inventory.md) — all UI components, their props/states, and which screens use them.
4. HTML prototypes (specs/ui/prototypes/*.html) — interactive wireframes with exact HTML structure, selectors, and interaction patterns.
5. FRDs (specs/frd-*.md) — for domain context and acceptance criteria.
6. PRD (specs/prd.md) — for overall product vision and success criteria.
7. .spec2cloud/state.json — confirm you are in Phase 2 (increment delivery), Step 1.
8. Increment plan (specs/increment-plan.md) — identify which flows are in scope for the current increment.

Generation Strategy

Step 1: Extract Flows from Walkthrough

Read specs/ui/flow-walkthrough.md and extract every user flow. A flow is a complete user journey with:

• A starting point (e.g., "user arrives at landing page")
• A sequence of actions (e.g., "clicks Sign Up → fills form → submits")
• An expected outcome (e.g., "sees dashboard with welcome message")

Create a mapping: flow name → list of screens traversed → expected outcome.

Step 2: Generate Page Object Models

For each screen in specs/ui/screen-map.md, create a POM class in e2e/pages/:

// e2e/pages/{screen-name}.page.ts
import { type Locator, type Page } from '@playwright/test';

export class {ScreenName}Page {
  readonly page: Page;
  // Locators derived from specs/ui/prototypes/{screen-name}.html
  readonly heading: Locator;
  readonly navLinks: Locator;
  // ... all interactive elements from the prototype

  constructor(page: Page) {
    this.page = page;
    // Selectors match the HTML structure in the prototype
    this.heading = page.getByRole('heading', { name: /.../ });
    this.navLinks = page.getByRole('navigation').getByRole('link');
  }

  async goto() {
    await this.page.goto('/{route}');
  }

  // Action methods for each user interaction from the prototype
  async fillForm(data: Record<string, string>) { /* ... */ }
  async submit() { /* ... */ }
}

POM rules:

• One POM per screen (1:1 with prototype HTML files)
• Selectors must match the HTML structure in specs/ui/prototypes/{screen-name}.html
• Use semantic selectors: getByRole, getByLabel, getByText — avoid CSS selectors
• Include action methods for every interaction shown in the prototype
• Include assertion helpers for verifying screen state

Step 3: Generate E2E Flow Specs

For each flow in flow-walkthrough.md, create a Playwright spec:

// e2e/{flow-name}.spec.ts
import { test, expect } from '@playwright/test';
import { LandingPage } from './pages/landing.page';
import { LoginPage } from './pages/login.page';
import { DashboardPage } from './pages/dashboard.page';

test.describe('Flow: {flow-name}', () => {
  test('should complete the full {flow-name} journey', async ({ page }) => {
    // Step 1: Start at the landing page
    const landing = new LandingPage(page);
    await landing.goto();
    await expect(landing.heading).toBeVisible();

    // Step 2: Navigate to login
    await landing.clickSignIn();
    const login = new LoginPage(page);
    await expect(login.emailInput).toBeVisible();

    // Step 3: Complete login
    await login.login('jane@example.com', 'SecureP@ss1');

    // Step 4: Verify dashboard
    const dashboard = new DashboardPage(page);
    await expect(page).toHaveURL(/\/dashboard/);
    await expect(dashboard.welcomeMessage).toContainText(/Welcome/);
  });
});

Spec rules:

• Each spec file exercises a complete user flow — not isolated page checks
• Tests navigate through the full journey as described in flow-walkthrough.md
• At each step, verify visual elements: headings, key content, navigation state
• Include assertions that confirm the app does what the PRD/FRDs describe
• Use POMs from Step 2 — never raw selectors in specs

Step 4: Generate Cross-Flow Specs

Identify flows that span multiple features or share navigation paths. Create cross-flow specs that verify:

• Navigation between features works (e.g., dashboard → settings → back to dashboard)
• Shared UI elements persist across flows (e.g., navigation bar, user avatar)
• State carries across flows (e.g., login state persists across page navigation)

Step 5: Tag and Organize

Apply tags consistently:

Aspire Environment

All e2e tests run against the Aspire-managed environment. The Playwright config already handles this:

• webServer in e2e/playwright.config.ts starts aspire start + aspire wait web
• Base URL defaults to http://localhost:3001 (Aspire web port)
• API is available at http://localhost:5001 (Aspire API port)
• Running locally via Aspire is non-negotiable — never start API/Web individually

Do NOT modify the Playwright config or webServer setup. Your tests run against the Aspire environment automatically.
