Iteration count in Postman - Test Execution Trace

Test Overview

This test checks that the Postman collection runs the expected number of iterations. It verifies the iteration count matches the configured value.

Test Code - Postman Test Script

Postman

pm.test('Iteration count is correct', function () {
    const expectedIterations = 3;
    const actualIterations = pm.info.iteration;
    pm.expect(actualIterations).to.be.below(expectedIterations);
});

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts in Postman runner	Postman collection runner is open with iteration count set to 3	-	PASS
2	Postman runs first iteration (iteration index 0)	Request sent, response received	Check pm.info.iteration is 0 and less than 3	PASS
3	Postman runs second iteration (iteration index 1)	Request sent, response received	Check pm.info.iteration is 1 and less than 3	PASS
4	Postman runs third iteration (iteration index 2)	Request sent, response received	Check pm.info.iteration is 2 and less than 3	PASS
5	Postman stops running after 3 iterations	Collection run complete	Total iterations run equals configured iteration count 3	PASS

Failure Scenario

Failing Condition: The iteration count exceeds the configured value or pm.info.iteration is incorrect

Execution Trace Quiz - 3 Questions

What does pm.info.iteration represent in the test script?

A The number of requests sent so far

B The total number of iterations configured

C The current iteration index starting from 0

D The response time of the request

Key Result

Always verify iteration count using pm.info.iteration to ensure your Postman collection runs the expected number of times.
