Response time in Postman - Test Execution Trace

Test Overview

This test sends a request to an API endpoint and verifies that the response time is within an acceptable limit, ensuring the API is fast enough for users.

Test Code - Postman

Postman

pm.test("Response time is less than 500ms", function () {
    pm.expect(pm.response.responseTime).to.be.below(500);
});

Execution Trace - 3 Steps

Step	Action	System State	Assertion	Result
1	Send HTTP GET request to the API endpoint	Postman sends the request and waits for the response	-	PASS
2	Receive response from the API	Response received with status code 200 and response time recorded	-	PASS
3	Check if response time is less than 500 milliseconds	Response time is measured (e.g., 350ms)	Assert responseTime < 500ms	PASS

Failure Scenario

Failing Condition: Response time is equal to or greater than 500 milliseconds

Execution Trace Quiz - 3 Questions

What does the test verify in this Postman script?

A The response status code is 500

B The response time is less than 500 milliseconds

C The response body contains a specific value

D The request method is POST

Key Result

Always verify response time to ensure your API meets performance expectations and provides a good user experience.
