Given this Flask test code:

with app.test_client() as client:
    response = client.get('/hello')
    print(response.status_code)
    print(response.data.decode())

If the '/hello' route returns 'Hello, World!' with status 200, what will be printed?

A200 Hello, World!

B404 Not Found

C500 Internal Server Error

D200 b'Hello, World!'

Step-by-Step Solution

Solution:

Step 1: Understand the route response
The route '/hello' returns the string 'Hello, World!' with HTTP status 200.
Step 2: Analyze the test output
The response.status_code will be 200. The response.data is bytes, so decoding it with decode() converts it to the string 'Hello, World!'.
Final Answer:
200 Hello, World! -> Option A
Quick Check:
Status 200 and decoded response text [OK]

Quick Trick: Decode response.data to get string content [OK]
