Req To Test

Feature: User Registration
  As a new user
  I want to create an account
  So that I can access the platform

  Scenario: Successful registration with valid credentials
    Given I am on the registration page
    And I am not logged in
    When I enter email "[email protected]"
    And I enter password "SecurePass123"
    And I click "Register"
    Then I see "Registration successful"
    And I am redirected to the dashboard
    And a confirmation email is sent to "[email protected]"

  Scenario: Registration fails with invalid email
    Given I am on the registration page
    When I enter email "invalid-email"
    And I enter password "SecurePass123"
    And I click "Register"
    Then I see error "Please enter a valid email address"
    And I remain on the registration page
    And no account is created

Test Suite: User Registration Validation

Test: test_validate_email_accepts_valid_format
  Setup: None required
  Input: email = "[email protected]"
  Execute: result = validate_email(email)
  Assert: result == True

Test: test_validate_email_rejects_invalid_format
  Setup: None required
  Input: email = "invalid-email"
  Execute: result = validate_email(email)
  Assert: result == False

Test: test_validate_email_rejects_empty_string
  Setup: None required
  Input: email = ""
  Execute: result = validate_email(email)
  Assert: result == False

Test: test_create_user_with_valid_data
  Setup:
    - Initialize database connection
    - Clear users table
  Input:
    - email = "[email protected]"
    - password = "SecurePass123"
  Execute: user = create_user(email, password)
  Assert:
    - user.email == "[email protected]"
    - user.password is hashed
    - user.created_at is set
    - user.id is generated
  Cleanup: Delete test user

Test: User Registration API Integration

Setup:
  - Start test server
  - Initialize test database
  - Configure email service mock

Steps:
  1. POST /api/register with valid credentials
  2. Verify API returns 201 Created
  3. Verify response contains user ID and token
  4. Query database for new user record
  5. Verify email service was called with correct parameters

Assertions:
  - API response status: 201
  - Response body contains: {id: <uuid>, token: <jwt>}
  - Database contains user with email "[email protected]"
  - User password is hashed (not plain text)
  - Email service called with subject "Welcome"
  - Confirmation link in email contains valid token

Cleanup:
  - Delete test user from database
  - Stop test server

Test: Complete User Registration and Login Journey

Scenario: New user registers and logs in successfully

  Given browser opens application homepage
  And no user exists with email "[email protected]"

  When user clicks "Sign Up" button
  Then registration page is displayed

  When user enters email "[email protected]"
  And user enters password "SecurePass123"
  And user enters password confirmation "SecurePass123"
  And user clicks "Create Account"
  Then success message "Account created successfully" appears
  And user is redirected to dashboard at "/dashboard"
  And welcome message displays "Welcome, [email protected]"

  When user logs out
  Then user is redirected to homepage

  When user clicks "Sign In"
  And user enters email "[email protected]"
  And user enters password "SecurePass123"
  And user clicks "Log In"
  Then user is redirected to dashboard
  And session is active

Verification:
  - User account persists in database
  - User can access protected resources
  - Session cookie is set correctly

Happy Path:
  - age = 25 (valid middle value)
  - age = 18 (minimum boundary)
  - age = 65 (maximum boundary)

Error Cases:
  - age = 17 (below minimum)
  - age = 66 (above maximum)
  - age = -5 (negative)
  - age = 0 (zero)
  - age = "twenty" (invalid type)
  - age = null (missing)
  - age = "" (empty string)
  - age = 999999 (extremely large)

Edge Cases:
  - age = 17.9 (decimal below minimum)
  - age = 18.0 (decimal at minimum)
  - age = 65.1 (decimal above maximum)
