Cucumber Gherkin-Style E2E Tests

This directory contains Gherkin-style acceptance tests using Cucumber and Playwright for testing the EuchreCamp application.

Overview

These tests follow the Given-When-Then syntax for behavior-driven development (BDD) and test the application from a user's perspective by interacting with the browser UI only.

Key Principles

1. Browser-only interactions: Tests interact with the application via the browser (click, type, navigate)
2. No direct database access: All data is created/modified through the UI
3. Dev site testing: Tests run against a running development server
4. Happy path focus: Tests verify common user workflows
5. Gherkin syntax: Tests are written in plain English using Given-When-Then

Running Tests

Run all Cucumber tests

bun run test:acceptance:cucumber

Run with pretty formatter (visible output)

bun run test:acceptance:cucumber:pretty

Run specific feature file

bun cucumber-js e2e/cucumber/features/user-registration.feature

Run specific scenario

bun cucumber-js --name "Successful registration with valid data"

Dry run (check for undefined steps)

bun cucumber-js --config e2e/cucumber/cucumber.config.ts --dry-run

Example Test

Feature File (user-registration.feature)

Feature: User Registration
  As a new user
  I want to register for an account
  So that I can participate in Euchre tournaments

  Background:
    Given I am on the registration page

  Scenario: Successful registration with valid data
    When I fill in "name" with "Test User"
    And I fill in "email" with "test@example.com"
    And I fill in "password" with "TestPassword123!"
    And I click the "Create Account" button
    Then I should be redirected to my profile page
    And my user account should exist

Step Definition (auth-steps.ts)

Given('I am logged in as a player', async function () {
  const credentials = generateTestCredentials();
  world.user = credentials;
  
  await world.page.goto(`${world.baseURL}/auth/register`);
  await world.page.fill('input[name="name"]', credentials.name);
  await world.page.fill('input[name="email"]', credentials.email);
  await world.page.fill('input[name="password"]', credentials.password);
  await world.page.click('button[type="submit"]');
  await world.page.waitForURL(/\/players\/\d+\/profile/);
});

Tags

Use tags to organize and filter tests:

• @happy-path - Tests successful user workflows
• @negative-test - Tests error cases and validation
• @authentication - Tests related to login/registration
• @wip - Work in progress (skipped by default)
• @skip - Temporarily skipped tests

Configuration

The Cucumber configuration is in cucumber.config.ts:

• Feature files: e2e/cucumber/features/**/*.feature
• Step definitions: e2e/cucumber/step-definitions/**/*.ts
• TypeScript loader: tsx (for path alias support)
• Tags: Skips @wip and @skip by default
• Retries: 2 retries in CI environment

World Context

The world.ts file provides a shared context for tests:

interface WorldState {
  page: Page;           // Playwright page
  context: BrowserContext;
  baseURL: string;      // Dev server URL
  user?: {              // Current test user
    email: string;
    name: string;
    password: string;
  };
  tournament?: any;     // Current test tournament
  player?: any;         // Current test player
}

Hooks

Hooks run before/after tests:

• BeforeAll - Launch browser once before all tests
• AfterAll - Close browser and cleanup after all tests
• Before - Create new page context before each scenario
• After - Close page and cleanup test data after each scenario

Best Practices

1. Unique test data: Use timestamps to ensure unique test users
2. Wait for navigation: Always wait for page loads and redirects
3. Clear assertions: Verify expected state after user actions
4. No database access: Use UI/API for all data creation
5. Tag organization: Use tags to filter test suites
6. One assertion per step: Keep steps focused and readable

Troubleshooting

Steps showing as undefined

Run with --dry-run to check step matching:

bun cucumber-js --dry-run

Database errors

These tests don't interact with the database directly. If you see Prisma errors, check that:

• The dev server is running
• The database is accessible
• Environment variables are set correctly

Slow tests

Use the @wip tag for tests in development and skip them during full runs.

CI/CD Integration

In CI, the tests should:

1. Start the dev server (if not already running)
2. Run Cucumber tests against http://localhost:3000
3. Use JUnit format for reporting:

   bun cucumber-js --format junit --out reports/cucumber.xml
