Local variables in Postman - Test Execution Trace

Test Overview

This test checks if a local variable set within a Postman request script is correctly assigned and used in an assertion to verify the response status code.

Test Code - Postman

Postman

pm.test("Status code is 200", function () {
    let expectedStatus = 200; // local variable
    pm.response.to.have.status(expectedStatus);
});

Execution Trace - 4 Steps

Step	Action	System State	Assertion	Result
1	Test script starts execution	Postman request has completed and response is available	-	PASS
2	Local variable 'expectedStatus' is assigned the value 200	Variable 'expectedStatus' holds 200 within the test function scope	-	PASS
3	Assertion checks if response status equals 'expectedStatus' (200)	Response status code is 200	pm.response.to.have.status(expectedStatus)	PASS
4	Test completes successfully	Test result recorded as pass	-	PASS

Failure Scenario

Failing Condition: Response status code is not 200
