What is Python integration testing and how do I implement it?

Python integration testing is a type of testing where individual modules are combined and tested as a group. It helps ensure that different parts of your application work together as expected. You can implement it using frameworks like pytest or unittest.

Can you give me an example of how to write an integration test in Python?

Sure! Here's a simple example using pytest:

import pytest
from my_app import create_app, db

@pytest.fixture
def client():
    app = create_app()
    app.config['TESTING'] = True
    with app.test_client() as client:
        with app.app_context():
            db.create_all()
        yield client
        with app.app_context():
            db.drop_all()

def test_integration(client):
    response = client.get('/api/data')
    assert response.status_code == 200

What are some common challenges in integration testing?

Common challenges include managing dependencies between modules, ensuring test data is consistent, and dealing with external services or APIs that may not be available during testing.

How can I automate my integration tests?

You can automate integration tests by using CI/CD tools like Jenkins, GitHub Actions, or Travis CI. These tools can run your tests automatically whenever you push code changes.
