How can I use Flask's test client for my application?

You can use Flask's test client to simulate requests to your application without running the server. It allows you to test your routes and views easily.

Can you show me a simple example of how to use it?

Sure! First, import the Flask app and create a test client instance. Then, you can use methods like client.get() or client.post() to make requests.

What about testing for specific responses?

You can assert the response data, status code, and headers. For example, assert response.status_code == 200 checks if the request was successful.

Are there any best practices for using the test client?

Yes, keep your tests isolated, use fixtures for setup, and ensure you cover various scenarios to validate your application thoroughly.
