Request methods and status codes in Testing Fundamentals - Test Execution Trace

Test Overview

This test checks if a web API correctly handles a GET request and returns the expected status code 200, indicating success.

Test Code - unittest

Testing Fundamentals

import requests
import unittest

class TestAPIRequestMethods(unittest.TestCase):
    def test_get_request_status_code(self):
        url = "https://jsonplaceholder.typicode.com/posts/1"
        response = requests.get(url)
        self.assertEqual(response.status_code, 200)

if __name__ == '__main__':
    unittest.main()

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Test framework initialized, ready to run test_get_request_status_code	-	PASS
2	Sends GET request to https://jsonplaceholder.typicode.com/posts/1	HTTP request sent to the API endpoint	-	PASS
3	Receives HTTP response from the server	Response object contains status code and data	-	PASS
4	Checks if response status code equals 200	Response status code is 200 OK	Assert response.status_code == 200	PASS
5	Test completes successfully	Test framework reports test passed	-	PASS

Failure Scenario

Failing Condition: The API returns a status code other than 200 (e.g., 404 or 500)
