💡 Hint

Common Mistakes

Using 'test_client' without parentheses creates a reference, not an instance.

Trying to call 'get' or 'post' directly on the app instead of on the test client.

The test_client() method creates a test client instance for the Flask app.

Using wrong header key names or values.

Status code 200 means success. The Content-Type header shows the response format. Checking header keys is case-sensitive.
