Bearer token in Postman - Test Execution Trace

Test Overview

This test sends an API request with a Bearer token for authorization. It verifies that the server accepts the token and returns a successful response.

Test Code - Postman Tests

Postman

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

pm.test("Response contains expected data", function () {
    const jsonData = pm.response.json();
    pm.expect(jsonData).to.have.property('userId');
});

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Open Postman and create a new GET request to the API endpoint	Postman UI shows the request setup screen with URL field empty	-	PASS
2	Set Authorization type to Bearer Token and enter the token value	Authorization tab shows Bearer Token selected and token input filled	-	PASS
3	Send the request to the server	Postman sends HTTP GET request with Authorization header: Bearer <token>	-	PASS
4	Receive response from server with status code 200 and JSON body	Response tab shows status 200 OK and JSON data including userId	Check that response status is 200	PASS
5	Run test script to verify response contains 'userId' property	Test results panel shows test execution	Verify response JSON has property 'userId'	PASS

Failure Scenario

Failing Condition: Bearer token is missing, expired, or invalid causing server to reject authorization
