Flask - Testing Flask Applications

You want to test a Flask route that returns JSON data {"success": true, "count": 5} with status 201. Which test code correctly verifies both the status and JSON content?

Aresponse = client.get('/data') assert response.status_code == 201 assert response.json() == {"success": True, "count": 5}

Bresponse = client.get('/data') assert response.status_code == 200 assert response.json == {"success": True, "count": 5}

Cresponse = client.post('/data') assert response.status_code == 200 assert response.get_json() == {"success": True, "count": 5}

Dresponse = client.get('/data') assert response.status_code == 201 assert response.get_json() == {"success": True, "count": 5}

Step-by-Step Solution

Solution:

Step 1: Check HTTP method and status code
The route returns status 201, so the test must assert response.status_code == 201. The method is GET as per the question.
Step 2: Verify JSON content correctly
Flask test response uses get_json() to parse JSON data. Using response.json is incorrect in Flask.
Final Answer:
response = client.get('/data') assert response.status_code == 201 assert response.get_json() == {"success": True, "count": 5} -> Option D
Quick Check:
Use get_json() and check status 201 [OK]

Quick Trick: Use get_json() to check JSON response content [OK]

Common Mistakes:

MISTAKES

Using response.json instead of get_json()
Checking wrong status code (200 instead of 201)
Using POST instead of GET method
