Feature #58: Playwright Test Helpers & Fixtures - Implementation Summary

Status: ✅ COMPLETE

All requirements from feature #58 have been successfully implemented.

Created Files

1. tests/e2e/helpers/fixtures.ts (377 lines)

Main implementation file with all required functionality:

• ✅ E2E User Type Definitions

  • E2EUserType type with all user types (landlord, tenant, admin, etc.)
  • E2E_USER_IDS constant matching services/e2eFixtures.ts
  • BASE_TIME constant for deterministic time (2024-01-15T12:00:00.000Z)

• ✅ useE2EUser() function

  • Sets x-e2e-user header for authenticated requests
  • Injects encryption bypass flag in localStorage
  • Adds route handler to inject headers in all browser requests

• ✅ applyDeterministicPage() function

  • Stubs Date.now() to return BASE_TIME
  • Stubs new Date() to use deterministic time
  • Stubs Math.random() for consistent sequences
  • Disables CSS animations and transitions
  • Sets timezone to UTC

• ✅ Test Data Generators

  • generateTestProperty() - creates unique test properties
  • generateTestLease() - creates unique test leases
  • generateTestMessage() - creates unique test messages
  • generateTestMaintenanceRequest() - creates unique test maintenance requests
  • All generators accept optional overrides for customization

• ✅ Helper Functions for Common Assertions

  • expectSuccess() - expects successful API response
  • expectStatus() - expects specific HTTP status
  • expectVisible() - expects element to be visible
  • expectText() - expects element to contain text
  • expectNoConsoleErrors() - expects no console errors
  • waitForPageLoad() - waits for page to fully load
  • takeScreenshot() - captures screenshots with automatic naming

• ✅ Additional Utilities

  • e2eHeaders() - creates headers object for API requests
  • ROUTES constant with common route paths
  • Extended Playwright test with custom fixtures

2. tests/helpers/test-utils.ts (Compatibility Layer)

Provides backward compatibility for existing tests:

• Re-exports all fixtures from tests/e2e/helpers/fixtures.ts
• Exports test and expect from Playwright
• Allows existing tests to import from ../../helpers/test-utils.ts

3. tests/e2e/example.test.ts (139 lines)

Demonstrates proper usage of all helpers:

• Basic UI tests with E2E user context
• API tests with E2E headers
• Test data generator usage
• Onboarding flow testing
• Data isolation testing between users
• Deterministic behavior verification

4. tests/e2e/sanity.test.ts (106 lines)

Verifies all helper functions work correctly:

• Tests all E2E user IDs
• Tests header generation
• Tests all data generators (uniqueness and overrides)
• Tests ROUTES constant
• API integration tests with real endpoints

5. tests/e2e/README.md (319 lines)

Comprehensive documentation:

• Overview of E2E infrastructure
• Available E2E users table with descriptions
• Test data available for each user type
• How-to guide for writing tests
• Helper function reference
• Routes reference
• Best practices
• Troubleshooting guide

Verification

TypeScript Type Checking

All files pass deno check without errors:

• ✅ tests/e2e/helpers/fixtures.ts
• ✅ tests/helpers/test-utils.ts
• ✅ tests/e2e/example.test.ts
• ✅ tests/e2e/sanity.test.ts

Integration with Existing Code

• ✅ Integrates with services/e2eFixtures.ts (uses same user IDs)
• ✅ Integrates with services/stateMiddleware.ts (uses x-e2e-user header)
• ✅ Backward compatible with existing tests via tests/helpers/test-utils.ts

Feature Requirements Checklist

From feature #58 description:

1. ✅ Create tests/e2e/helpers/fixtures.ts with E2E user type definitions and helper functions
2. ✅ Implement useE2EUser() fixture to set x-e2e-user header for authenticated requests
3. ✅ Implement applyDeterministicPage() to mock time and ensure consistent test runs
4. ✅ Create test data generators for properties, leases, and messages
5. ✅ Add helper functions for common assertions (expectSuccess, expectError, etc.)

All requirements met! ✅

Usage Example

import { expect, test } from "@playwright/test";
import {
  applyDeterministicPage,
  e2eHeaders,
  generateTestProperty,
  ROUTES,
  useE2EUser,
} from "../helpers/fixtures.ts";

test("landlord can create property", async ({ page, request }) => {
  await applyDeterministicPage(page);
  await useE2EUser(page, "landlord");

  // Navigate to properties page
  await page.goto(ROUTES.landlordProperties);

  // Or test via API
  const newProperty = generateTestProperty({ title: "Test Property" });
  const response = await request.post("/api/create/property", {
    headers: e2eHeaders("landlord"),
    data: newProperty,
  });

  expect(response.ok()).toBeTruthy();
});

Next Steps

This infrastructure is now ready for use by other E2E tests. Existing tests can be updated to use these helpers for more reliable and maintainable test code.
