Run Integration Tests

run-integration-tests

Skill Type: Test Runner Purpose: Execute integration tests validating system behavior Prerequisites: Integration tests exist (BDD scenarios, API tests, E2E tests)

Agent Instructions

You are running integration tests to validate the integrated system.

Integration tests validate:

• Cross-component interactions
• End-to-end user flows
• API contracts
• Database integration
• External service integration
• BDD scenarios (Given/When/Then)

Workflow

Step 1: Discover Integration Tests

Find all integration test files:

# BDD scenarios
find features -name "*.feature"

# Integration test directories
find tests/integration -name "test_*.py"
find tests/e2e -name "test_*.py"
find tests/api -name "test_*.py"

Step 2: Run BDD Scenarios

Execute Gherkin scenarios:

# Behave (Python)
behave features/ --format progress

# Cucumber (JavaScript)
npm run cucumber

# Cucumber (Java)
mvn test -Dcucumber.options="features/"

Output:

Feature: User Authentication
  Scenario: Successful login                    PASSED
  Scenario: Login fails with invalid email      PASSED
  Scenario: Account locks after 3 failures      PASSED

Feature: Payment Processing
  Scenario: Successful card payment             PASSED
  Scenario: Payment fails invalid card          PASSED

5 scenarios (5 passed)
27 steps (27 passed)
Duration: 2.3s

Step 3: Run API Integration Tests

Execute API test suite:

# Python (pytest with requests)
pytest tests/integration/api/ -v

# JavaScript (supertest)
npm test tests/integration/api

# Java (RestAssured)
mvn test -Dtest=ApiIntegrationTest

Example tests:

# tests/integration/api/test_auth_api.py
# Validates: <REQ-ID> (API integration)

def test_login_api_returns_token():
    response = requests.post(
        "http://localhost:8000/api/auth/login",
        json={"email": "user@example.com", "password": "SecurePass123!"}
    )
    assert response.status_code == 200
    assert "token" in response.json()

def test_login_api_rejects_invalid_email():
    response = requests.post(
        "http://localhost:8000/api/auth/login",
        json={"email": "invalid", "password": "SecurePass123!"}
    )
    assert response.status_code == 400
    assert response.json()["error"] == "Invalid email format"

Step 4: Run Database Integration Tests

Execute tests with real database:

# tests/integration/database/test_user_db.py
# Validates: <REQ-ID> (database integration)

def test_user_registration_persists_to_database(db_session):
    """Test user registration saves to database"""
    user = register("new@example.com", "SecurePass123!")

    # Verify user in database
    db_user = db_session.query(User).filter_by(email="new@example.com").first()
    assert db_user is not None
    assert db_user.email == "new@example.com"

Step 5: Run End-to-End Tests

Execute full user journeys:

# tests/e2e/test_user_flow.py
# Validates: INT-100 (complete user authentication flow)

def test_complete_registration_and_login_flow(browser):
    """Test complete user journey: register → login → access protected page"""

    # Register
    browser.visit("/register")
    browser.fill("email", "newuser@example.com")
    browser.fill("password", "SecurePass123!")
    browser.click("Register")
    assert browser.is_text_present("Registration successful")

    # Login
    browser.visit("/login")
    browser.fill("email", "newuser@example.com")
    browser.fill("password", "SecurePass123!")
    browser.click("Login")
    assert browser.is_text_present("Welcome")

    # Access protected page
    browser.visit("/dashboard")
    assert browser.is_text_present("Dashboard")  # Not redirected to login

Step 6: Aggregate Results

Collect all test results:

Integration Test Summary:

BDD Scenarios:
  ✓ 12 scenarios, all passing
  ✓ 67 steps, all passing
  ✓ Duration: 5.2s

API Integration Tests:
  ✓ 24 tests passing
  ✓ Duration: 3.8s

Database Integration Tests:
  ✓ 15 tests passing
  ✓ Duration: 8.1s

End-to-End Tests:
  ✓ 6 tests passing
  ✓ Duration: 42.5s

Total: 57 integration tests
Pass Rate: 100%
Total Duration: 59.6s

Step 7: Map Tests to Requirements

Show which requirements validated:

Requirements Validated by Integration Tests:

<REQ-ID> (User login):
  ✓ BDD: features/authentication.feature (3 scenarios)
  ✓ API: tests/integration/api/test_auth_api.py (5 tests)
  ✓ E2E: tests/e2e/test_user_flow.py (1 test)
  Total: 9 integration tests ✅

<REQ-ID> (Payment processing):
  ✓ BDD: features/payments.feature (2 scenarios)
  ✓ API: tests/integration/api/test_payment_api.py (8 tests)
  Total: 10 integration tests ✅

REQ-NFR-PERF-001 (Performance):
  ✗ No integration tests ❌
  Recommendation: Add performance tests

Coverage: 90% of requirements have integration tests

   All tests passing
   Minor gaps identified

Prerequisites Check

Before invoking:

1. Integration test files exist
2. Test dependencies installed (behave, requests, selenium, etc.)
3. Test environment available (database, services running)

Configuration

plugins:
  - name: "@aisdlc/testing-skills"
    config:
      integration_tests:
        auto_run_on_commit: false
        timeout_seconds: 300
        parallel_execution: true
        frameworks:
          bdd: "behave"
          api: "pytest"
          e2e: "selenium"
        require_for_deploy: true

Notes

Why integration tests?

• Validate system behavior (not just unit behavior)
• Catch integration bugs (component A + B works, but A+B+C fails)
• Validate user flows (BDD scenarios)
• Pre-deployment quality gate

Integration vs Unit Tests:

Unit Tests: Test individual functions/classes
  - Fast (milliseconds)
  - Many tests (hundreds)
  - Run frequently (every save)

Integration Tests: Test components together
  - Slower (seconds/minutes)
  - Fewer tests (dozens)
  - Run on commits/deployments

Homeostasis Goal:

desired_state:
  all_integration_tests_passing: true
  all_requirements_have_integration_tests: true
