Environment variables in Postman - Test Execution Trace

Test Overview

This test checks if the Postman environment variable baseUrl is correctly used to send a GET request and verifies the response status code is 200.

Test Code - Postman

Postman

pm.test("Status code is 200", function () {
    pm.sendRequest({
        url: pm.environment.get("baseUrl") + "/api/users",
        method: 'GET'
    }, function (err, res) {
        pm.expect(res).to.have.property('status', 200);
    });
});

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	Retrieve environment variable 'baseUrl'	Environment variable 'baseUrl' is set, e.g., 'https://reqres.in'	Check that 'baseUrl' is not null or empty	PASS
3	Send GET request to 'https://reqres.in/api/users'	Request sent to the server using the URL constructed from environment variable	-	PASS
4	Receive response from server	Server responds with HTTP status code 200 and user data JSON	Verify response status code equals 200	PASS
5	Assertion checks pass confirming status code is 200	Test runner logs success for the assertion	pm.expect(res).to.have.property('status', 200)	PASS

Failure Scenario

Failing Condition: Environment variable 'baseUrl' is missing or incorrect, or server returns status code other than 200

Execution Trace Quiz - 3 Questions

What does the test verify using the environment variable?

A It checks if the environment variable contains user data

B It tests if the environment variable is empty

C It verifies the response status code from the URL built using the environment variable

D It verifies the request method is POST

Key Result

Always use environment variables to make your tests flexible and reusable across different environments without changing the test code.
