GraphQL body in Postman - Test Execution Trace

Test Overview

This test sends a GraphQL query in the request body using Postman. It verifies that the response contains the expected data field with correct values.

Test Code - Postman Test Script

Postman

pm.test("GraphQL response contains user data", function () {
    const jsonData = pm.response.json();
    pm.expect(jsonData.data).to.have.property('user');
    pm.expect(jsonData.data.user).to.have.property('id').that.is.a('string');
    pm.expect(jsonData.data.user).to.have.property('name').that.is.a('string');
});

Execution Trace - 8 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Postman is ready with GraphQL request body set	-	PASS
2	Send POST request with GraphQL query in body	Request sent to GraphQL endpoint with body containing query { user { id name } }	-	PASS
3	Receive response from server	Response received with JSON body containing data.user object	-	PASS
4	Parse response JSON	Response body parsed into jsonData object	-	PASS
5	Check if 'data' property exists	jsonData contains 'data' key	pm.expect(jsonData.data).to.have.property('user')	PASS
6	Check if 'user' object has 'id' property of type string	jsonData.data.user has 'id' key with string value	pm.expect(jsonData.data.user).to.have.property('id').that.is.a('string')	PASS
7	Check if 'user' object has 'name' property of type string	jsonData.data.user has 'name' key with string value	pm.expect(jsonData.data.user).to.have.property('name').that.is.a('string')	PASS
8	Test ends with all assertions passed	All expected fields verified in response	-	PASS

Failure Scenario

Failing Condition: Response JSON does not contain 'data.user' or 'id'/'name' fields are missing or not strings

Execution Trace Quiz - 3 Questions

What does the test verify first in the GraphQL response?

A That the 'data' object contains a 'user' property

B That the HTTP status code is 200

C That the response time is less than 1 second

D That the 'errors' field is empty

Key Result

Always verify the structure and data types of the GraphQL response fields to ensure the API returns the expected data format.
