Path parameters in Postman - Test Execution Trace

Test Overview

This test sends a GET request using Postman with a path parameter to retrieve a specific user's details. It verifies that the response status is 200 and the returned user ID matches the path parameter.

Test Code - Postman

Postman

pm.test("Status code is 200", function () {
    pm.response.to.have.status(200);
});

pm.test("Response has correct user ID", function () {
    const userId = pm.variables.get("userId");
    const jsonData = pm.response.json();
    pm.expect(jsonData.id).to.eql(parseInt(userId));
});

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Postman app is open with the GET request configured to https://api.example.com/users/:userId with userId=5	-	PASS
2	Send GET request to https://api.example.com/users/5	Request sent, waiting for response	-	PASS
3	Receive response with status 200 and JSON body {"id":5, "name":"John Doe"}	Response received in Postman	Check response status is 200	PASS
4	Run test to verify response status code	Test script executes	pm.response.to.have.status(200)	PASS
5	Run test to verify response user ID matches path parameter	Test script executes	pm.expect(jsonData.id).to.eql(5)	PASS

Failure Scenario

Failing Condition: Response status is not 200 or returned user ID does not match the path parameter

Execution Trace Quiz - 3 Questions

What does the test verify first after sending the GET request?

A Request URL contains query parameters

B Response body contains user name

C Response status code is 200

D Response time is less than 1 second

Key Result

Always verify that path parameters are correctly inserted in the request URL and that the response matches the expected data for those parameters.
