Request headers in Postman - Test Execution Trace

Test Overview

This test sends an HTTP GET request with custom request headers using Postman. It verifies that the server receives the headers correctly and responds with status 200.

Test Code - Postman

Postman

pm.test("Verify response status and headers", function () {
    pm.response.to.have.status(200);
    pm.expect(pm.request.headers.get('X-Custom-Header')).to.eql('TestValue');
    pm.expect(pm.request.headers.get('Accept')).to.eql('application/json');
});

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Open Postman and create a new GET request to https://api.example.com/data	Postman UI shows the new GET request with the URL entered	-	PASS
2	Add request headers: 'X-Custom-Header' with value 'TestValue' and 'Accept' with value 'application/json'	Headers tab shows the two headers correctly added	-	PASS
3	Send the request by clicking the Send button	Postman sends the HTTP GET request with the headers to the server	-	PASS
4	Receive the response from the server	Response tab shows status 200 and response body	Verify response status is 200	PASS
5	Run test script to verify request headers were sent correctly	Test script executes in Postman test runner	Check that 'X-Custom-Header' equals 'TestValue' and 'Accept' equals 'application/json'	FAIL

Failure Scenario

Failing Condition: Request headers are missing or have incorrect values
