Walkthrough

New comprehensive test modules and fixtures have been added to the backend, focusing on authentication routes and services. The changes introduce pytest-based test suites for email and Google authentication, token management, and password reset flows. Supporting dependencies and fixtures for in-memory MongoDB testing and asynchronous test execution are also included.

Changes

File(s) Change Summary
backend/app/tests/conftest.py Added pytest fixtures for mongomock database, FastAPI TestClient, and mocked AuthService.
backend/app/tests/test_auth_routes.py Added extensive async tests for authentication endpoints, covering success and error scenarios.
backend/app/tests/test_auth_service.py Added async tests for AuthService covering user creation, token management, and Google auth.
backend/requirements.txt Added pytest, pytest-asyncio, and mongomock for testing support.

Poem

In the warren where code and tests meet,
New fixtures and mocks make our coverage complete.
With mongomock magic and pytest delight,
We check every token by day and by night.
🐇 Here’s to new tests—may our backend hop right!

-pytest
-pytest-asyncio
-mongomock
+pytest==8.3.4
+pytest-asyncio==0.24.0
+mongomock==4.2.0
backend/app/tests/conftest.py (2)

4-4: Remove unused import.

The patch import from unittest.mock is not used in this file and should be removed.

-from unittest.mock import patch

10-10: Remove unused import.

The close_mongo_connection import is not used in this file and should be removed.

-from app.database import get_database, close_mongo_connection # Assuming you have a close connection function
+from app.database import get_database
backend/app/tests/test_auth_service.py (2)

4-5: Remove unused imports.

Several imports are not used in this test file and should be removed for cleaner code.

-from app.auth.schemas import UserResponse # Assuming this is used or relevant for response assertions
-from unittest.mock import patch, AsyncMock, MagicMock # For mocking async methods if needed
+from unittest.mock import patch # For mocking async methods if needed

154-211: Consider breaking down this complex test function.

This test function has 17 local variables, which exceeds the recommended limit. Consider breaking it into smaller, focused test functions for better readability and maintainability.

@pytest.mark.asyncio
async def test_confirm_password_reset_success_setup(auth_service_mocked: AuthService, db):
    # Setup user and reset token
    email = "confirm_reset@example.com"
    old_password = "oldPassword123"
    new_password = "newPassword456"
    name = "Confirm Reset User"
    
    created_user_data = await auth_service_mocked.create_user_with_email(email, old_password, name)
    user_id_obj = ObjectId(created_user_data["user"]["_id"])
    
    # Create password reset token
    reset_token_value = "valid_reset_token_for_confirm"
    reset_expires = datetime.utcnow() + timedelta(hours=1)
    await db.password_resets.insert_one({
        "user_id": user_id_obj,
        "token": reset_token_value,
        "expires_at": reset_expires,
        "used": False,
        "created_at": datetime.utcnow()
    })

    # Test password reset confirmation
    result = await auth_service_mocked.confirm_password_reset(reset_token_value, new_password)
    assert result is True
    
    # Verify password was updated and tokens revoked
    # ... rest of verification logic
backend/app/tests/test_auth_routes.py (2)

3-3: Remove unused import.

The get_database import is not used in this test file and should be removed.

-from app.database import get_database # Or use the 'db' fixture directly

247-306: Consider simplifying this complex test function.

This test has 18 local variables, exceeding the recommended limit. Consider extracting helper functions or breaking into smaller test cases for better maintainability.

async def create_initial_user_for_google_test(db, email, original_name, original_picture):
    """Helper function to create initial user for Google login tests."""
    initial_user_doc = {
        "email": email,
        "name": original_name,
        "avatar": original_picture,
        "currency": "USD",
        "created_at": datetime.utcnow(),
        "auth_provider": "email",
        "firebase_uid": None,
        "hashed_password": "somepasswordhash"
    }
    insert_result = await db.users.insert_one(initial_user_doc)
    return insert_result.inserted_id

@pytest.mark.asyncio
async def test_login_with_google_existing_user(client: TestClient, db):
    # Use helper function to reduce complexity
    user_id_obj = await create_initial_user_for_google_test(
        db, email, original_name, original_picture
    )
    # ... rest of test logic

backend/app/tests/conftest.py (2)

23-44: Excellent fixture design with proper cleanup.

The database fixture implementation is well-designed with proper dependency override, cleanup, and restoration. The function scope ensures test isolation, and the cleanup logic handles both collections and dependency restoration correctly.


8-8: Verify import path for app.main.

Static analysis indicates that module 'app' has no name 'main'. Please verify that the import path is correct for your project structure.

#!/bin/bash
# Check if app.main module exists and has the app instance
fd -t f "main.py" backend/app/
ast-grep --pattern 'app = $_'
backend/app/tests/test_auth_service.py (3)

17-41: Excellent comprehensive test for user creation.

The test thoroughly validates user creation with proper database verification, password hashing, and refresh token generation. Good use of async/await and database assertions.


367-368: Hardcoded secret is appropriate for testing.

The hardcoded JWT secret "wrongsecret" is intentionally used to test invalid token signatures. This is a valid testing pattern and not a security concern in test code.


538-660: Excellent Google authentication test coverage.

The Google authentication tests provide comprehensive coverage including new user creation, existing user updates, invalid tokens, and missing email scenarios. Good use of mocking for Firebase dependencies.

backend/app/tests/test_auth_routes.py (3)

16-48: Excellent route testing pattern.

The signup test provides comprehensive validation of the FastAPI endpoint including request/response validation, database persistence verification, and proper use of test fixtures.


509-514: Hardcoded secret is appropriate for testing.

The hardcoded JWT secret "a_completely_wrong_secret_key" is intentionally used to test invalid token signatures. This is a valid testing pattern and not a security concern in test code.


567-573: Comprehensive token verification test coverage.

The token verification tests provide excellent coverage of success and failure scenarios, properly testing authentication edge cases with appropriate error handling validation.

google-labs-jules bot and others added 9 commits June 19, 2025 10:55
This commit finalizes the addition of tests for the authentication service and introduces a GitHub Actions workflow to automate test execution.

Summary of changes:

1.  **Testing Environment & Fixtures**:
    *   `pytest`, `pytest-asyncio`, `mongomock` added to `backend/requirements.txt`.
    *   Test fixtures for mock DB, AuthService, and TestClient created in `backend/app/tests/conftest.py`.

2.  **Unit Tests (`backend/app/tests/test_auth_service.py`)**:
    *   Comprehensive unit tests written for all methods in `AuthService`, covering various success, error, and edge case scenarios. External dependencies like Firebase are mocked.

3.  **Integration Tests (`backend/app/tests/test_auth_routes.py`)**:
    *   Added integration tests for all authentication-related API endpoints:
        *   `POST /auth/signup/email`
        *   `POST /auth/login/email`
        *   `POST /auth/login/google` (with service-level mocking for Firebase)
        *   `POST /auth/refresh`
        *   `POST /auth/token/verify`
        *   `POST /auth/password/reset/request`
        *   `POST /auth/password/reset/confirm`
    *   These tests verify API request/response cycles, database interactions (using mongomock), and error handling.

4.  **GitHub Actions Workflow (`.github/workflows/backend-tests.yml`)**:
    *   A new workflow is added to automatically run backend tests on pushes and pull requests to the `main` branch that affect backend code.
    *   The workflow sets up Python, installs dependencies, and executes `pytest`.

This enhances the reliability and maintainability of the backend authentication system by providing a solid automated testing foundation.
Updates the backend testing workflow (`.github/workflows/backend-tests.yml`)
to explicitly set `PYTHONPATH=.` for the pytest execution step.

This ensures that modules within the `backend/app` directory are correctly
discovered and imported by pytest during CI runs, addressing the
`ModuleNotFoundError: No module named 'app.main'` error previously
encountered.
- Created a new test file `test_auth_service.py` with extensive unit tests for the AuthService methods, including user creation, authentication, password reset, and token verification.
- Implemented various test cases to cover success scenarios, error handling, and edge cases for user authentication and token management.
- Added a `conftest.py` file to set up a mock MongoDB client using mongomock, along with fixtures for database access and AuthService instantiation.
- Ensured that the test environment is isolated and cleans up after each test to maintain integrity.
