How can I test my Flask application using pytest?

You can test your Flask application using pytest by creating test files that import your app and use pytest's features.

What are some basic tests I should write for my Flask app?

Start with tests for your routes, checking for correct status codes and responses, and then test your forms and models.

Can you show me an example of a simple test?

Sure! Here's a simple test for a route:

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

This checks if the home page loads successfully.

How do I run my tests?

You can run your tests by executing pytest in your terminal from the root directory of your project.
