Tests tab and pm.test() in Postman - Test Execution Trace

Test Overview

This test checks if the API response status is 200 and if the response body contains a specific key. It uses pm.test() in Postman's Tests tab to verify these conditions.

Test Code - Postman Tests tab

Postman

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

pm.test("Response has userId", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData).to.have.property('userId');
});

Execution Trace - 3 Steps

Step	Action	System State	Assertion	Result
1	Test starts in Postman Tests tab	Postman is ready to run the test scripts after receiving the API response	-	PASS
2	pm.test("Status code is 200") runs and checks response status	API response received with HTTP status code 200	Verify response status code equals 200	PASS
3	pm.test("Response has userId") runs and checks response body	Response body parsed as JSON, contains key 'userId'	Verify response JSON has property 'userId'	PASS

Failure Scenario

Failing Condition: Response status is not 200 or response JSON does not have 'userId' property

Execution Trace Quiz - 3 Questions

What does the first pm.test() check in this test?

A That the response time is less than 200ms

B That the response status code is 200

C That the response body contains 'userId'

D That the response headers include Content-Type

Key Result

Use pm.test() in Postman's Tests tab to write clear, separate checks for response status and body content, making it easy to identify which part fails.
