Conditional request execution (setNextRequest) in Postman - Test Execution Trace

Test Overview

This test checks if the Postman collection runs the next request conditionally based on the response of the current request. It verifies that setNextRequest correctly directs the flow.

Test Code - Postman

Postman

pm.test("Check response status and set next request", function () {
    pm.response.to.have.status(200);
    const jsonData = pm.response.json();
    if (jsonData.success === true) {
        pm.setNextRequest("Request B");
    } else {
        pm.setNextRequest(null); // stops the run
    }
});

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts and sends 'Request A' to the server	Postman sends HTTP request 'Request A' and waits for response	-	PASS
2	Postman receives response for 'Request A'	Response status 200 and JSON body received	Check response status is 200	PASS
3	Test script parses JSON response and checks if 'success' is true	JSON parsed, 'success' field evaluated	-	PASS
4	Based on condition, setNextRequest is called with 'Request B'	Postman sets next request to 'Request B'	-	PASS
5	Postman sends 'Request B' as next request	Request B sent to server	-	PASS

Failure Scenario

Failing Condition: Response status is not 200

Execution Trace Quiz - 3 Questions

What does setNextRequest("Request B") do in this test?

A It tells Postman to run 'Request B' next

B It stops the collection run immediately

C It retries the current request

D It skips 'Request B' and runs the next request

Key Result

Use setNextRequest to control the flow of requests dynamically based on response data, enabling conditional testing scenarios in Postman collections.
