Test Overview

This test sends a GET request to an API endpoint and verifies that the response body contains the expected user data, including the user's name and email.

Test Code - Postman

Postman

pm.test("Response body contains correct user data", function () {
    const responseJson = pm.response.json();
    pm.expect(responseJson).to.have.property('name', 'John Doe');
    pm.expect(responseJson).to.have.property('email', 'john.doe@example.com');
});

Execution Trace - 7 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Postman is ready to send the request	-	PASS
2	Send GET request to API endpoint	Request sent to https://api.example.com/users/123	-	PASS
3	Receive response with status 200 and JSON body	Response body: {"id":123,"name":"John Doe","email":"john.doe@example.com"}	Status code is 200	PASS
4	Parse response body as JSON	Parsed JSON object available for assertions	-	PASS
5	Assert response JSON has property 'name' with value 'John Doe'	Checking 'name' property in response JSON	responseJson.name === 'John Doe'	PASS
6	Assert response JSON has property 'email' with value 'john.doe@example.com'	Checking 'email' property in response JSON	responseJson.email === 'john.doe@example.com'	PASS
7	Test ends	All assertions passed	-	PASS

Failure Scenario

Failing Condition: Response JSON does not contain the expected 'name' or 'email' properties with correct values

Execution Trace Quiz - 3 Questions

Test your understanding

What does the test verify about the response body?

AIt confirms the response body is empty.

BIt verifies the response status code is 404.

CIt checks that the response JSON contains the correct 'name' and 'email' properties.

DIt checks that the response headers contain 'Content-Type: text/html'.

Key Result

Always assert specific properties and their expected values in the response body to ensure the API returns correct data.
