Reusable test scripts in Postman - Test Execution Trace

Test Overview

This test checks if the reusable test script correctly validates the response status and content type for an API endpoint. It verifies that the response status is 200 and the content type is JSON.

Test Code - Postman

Postman

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

pm.test("Content-Type is application/json", function () {
    pm.response.to.have.header("Content-Type", /application\/json/);
});

Execution Trace - 3 Steps

Step	Action	System State	Assertion	Result
1	Test starts and sends API request	Postman sends HTTP request to the API endpoint	-	PASS
2	Check if response status code is 200	Response received with status code 200	pm.response.to.have.status(200)	PASS
3	Check if Content-Type header includes 'application/json'	Response headers include Content-Type: application/json	pm.response.to.have.header("Content-Type", /application\/json/)	PASS

Failure Scenario

Failing Condition: Response status code is not 200 or Content-Type header is missing or incorrect

Execution Trace Quiz - 3 Questions

What does the first test in the script verify?

A Response status code is 200

B Response body contains JSON data

C Response time is less than 200ms

D Response header includes Authorization

Key Result

Using reusable test scripts in Postman helps quickly verify common response properties like status code and headers across multiple API requests, saving time and ensuring consistency.
