Test utilities and helpers in Postman - Test Execution Trace

Test Overview

This test uses Postman test utilities to check if the API response status is 200 and if the response body contains a specific key with the expected value.

Test Code - Postman

Postman

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

pm.test("Response has userId with value 1", function () {
    const jsonData = pm.response.json();
    pm.expect(jsonData.userId).to.eql(1);
});

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Postman app is open with the API request ready	-	PASS
2	Send API request	Request sent to the server, waiting for response	-	PASS
3	Receive API response	Response received with status 200 and JSON body	Check if response status is 200	PASS
4	Parse response JSON	Response body parsed into JSON object	Verify jsonData.userId equals 1	PASS
5	Test ends	All assertions passed, test completed successfully	-	PASS

Failure Scenario

Failing Condition: Response status is not 200 or userId value is not 1

Execution Trace Quiz - 3 Questions

What does the first test in the Postman script verify?

A The response status code is 200

B The response body contains userId

C The response time is less than 200ms

D The request headers are correct

Key Result

Using Postman's built-in test utilities like pm.response.to.have.status and pm.expect helps write clear and reliable tests that verify API responses effectively.
