E2E Test Generator

Generate end-to-end tests for: $0

Framework: $1 (default: playwright)

Steps

1. Map the user flow — Break the feature into discrete user actions:

   • Navigate to page
   • Fill form / click button / interact with element
   • Wait for response / navigation
   • Verify result (visible text, URL change, element state)

2. Identify test scenarios:

   • Happy path — complete flow with valid inputs
   • Validation — form errors, required fields
   • Auth states — logged in, logged out, wrong role
   • Responsive — mobile vs desktop if layout changes behavior

3. Write tests:

import { test, expect } from "@playwright/test";

test.describe("Checkout Flow", () => {
  test.beforeEach(async ({ page }) => {
    // Seed test data or use API to set up state
    await page.goto("/products");
  });

  test("user can complete a purchase", async ({ page }) => {
    // Add item to cart
    await page.click('[data-testid="add-to-cart-btn"]');
    await expect(page.locator('[data-testid="cart-count"]')).toHaveText("1");

    // Go to checkout
    await page.click('[data-testid="checkout-btn"]');
    await expect(page).toHaveURL(/\/checkout/);

    // Fill shipping
    await page.fill('[name="address"]', "123 Test St");
    await page.fill('[name="city"]', "Test City");
    await page.click('[data-testid="continue-btn"]');

    // Confirm order
    await page.click('[data-testid="place-order-btn"]');
    await expect(page.locator("h1")).toHaveText("Order Confirmed");
  });

  test("shows validation errors for empty shipping form", async ({ page }) => {
    await page.click('[data-testid="add-to-cart-btn"]');
    await page.click('[data-testid="checkout-btn"]');
    await page.click('[data-testid="continue-btn"]');

    await expect(page.locator('[data-testid="address-error"]')).toBeVisible();
  });
});

4. Add page objects (if the flow is complex):

class CheckoutPage {
  constructor(private page: Page) {}

  async fillShipping(address: string, city: string) {
    await this.page.fill('[name="address"]', address);
    await this.page.fill('[name="city"]', city);
  }

  async placeOrder() {
    await this.page.click('[data-testid="place-order-btn"]');
  }
}

5. Configure test setup — Auth state, test data seeding, cleanup.

Output Format

• Test files in e2e/ or tests/e2e/ directory
• Page objects in e2e/pages/ if needed
• Include any needed test fixtures or global setup

Constraints

• Use data-testid attributes for selectors — never select by CSS class or text content that may change
• Tests must be independent — no shared state between tests
• Avoid page.waitForTimeout() — use expect with auto-waiting or waitForSelector
• Keep tests focused — one user flow per test, not the entire app
• Don't test API logic in E2E — that's what integration tests are for
• Always clean up test data (API calls in afterAll or database reset)
