What is wrong with this Flask test code snippet?

client = app.test_client()
response = client.get('/missing')
assert response.status_code == 200

Assuming '/missing' route does not exist.

AThe status code will be 404, so the assertion fails

BThe get method should be post for missing routes

CThe test client must be used inside a context manager

DThe response object does not have status_code attribute

Step-by-Step Solution

Solution:

Step 1: Check the route existence
The route '/missing' does not exist, so Flask returns a 404 Not Found status.
Step 2: Evaluate the assertion
The assertion expects status code 200, but the actual is 404, causing the test to fail.
Final Answer:
The status code will be 404, so the assertion fails -> Option A
Quick Check:
Missing route returns 404, assertion expects 200 [OK]

Quick Trick: Check route exists before asserting status 200 [OK]
