Timestamp generation in Postman - Test Execution Trace

Test Overview

This test checks if the Postman script correctly generates a current timestamp and verifies its format and value.

Test Code - Postman

Postman

pm.test("Timestamp is generated and valid", function () {
    const timestamp = Date.now();
    pm.environment.set("currentTimestamp", timestamp);
    pm.expect(timestamp).to.be.a('number');
    pm.expect(timestamp).to.be.above(0);
});

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Postman test runner is ready to execute the test script	-	PASS
2	Generates current timestamp using Date.now()	Timestamp is a numeric value representing milliseconds since Unix epoch	Check that timestamp is a number	PASS
3	Stores timestamp in Postman environment variable 'currentTimestamp'	Environment variable 'currentTimestamp' holds the timestamp value	-	PASS
4	Asserts timestamp is greater than zero	Timestamp value is positive and valid	Verify timestamp > 0	PASS
5	Test ends	Test completed successfully with all assertions passing	-	PASS

Failure Scenario

Failing Condition: Timestamp is not generated or is not a number

Execution Trace Quiz - 3 Questions

What does the test verify about the timestamp?

A That it is exactly the current date and time as a string

B That it is a string in ISO format

C That it is a number and greater than zero

D That it is stored in a global variable

Key Result

Always verify that generated timestamps are numeric and positive to ensure valid time values before using them in tests or requests.
