How can I perform integration testing in Flask?

You can perform integration testing in Flask using the built-in test client. Would you like a code example?

Yes, please provide a code example for integration testing.

Sure! Here's a simple example:

import pytest
from myapp import create_app

@pytest.fixture
def client():
    app = create_app()
    with app.test_client() as client:
        yield client

def test_homepage(client):
    response = client.get('/')
    assert response.status_code == 200
    assert b'Welcome' in response.data

What libraries do I need to install for this?

You need to install Flask and pytest. You can do this using pip:

pip install Flask pytest
