How can I set up testing for my Flask application?

To set up testing in Flask, you can use the built-in unittest framework or pytest. Do you have a preference?

I prefer using pytest. What are the steps to get started?

First, install pytest with pip install pytest. Then, create a test file, typically named test_*.py, and write your test functions.

What should I include in my test functions?

Include assertions to check the expected outcomes of your Flask routes and functions. You can use Flask's test client for this.

Can you give me an example of a simple test?

Sure! Here's a simple test:

def test_home_page(client):
    response = client.get('/')
    assert response.status_code == 200

This checks if the home page loads successfully.
