Query parameters in Postman - Test Execution Trace

Test Overview

This test sends a GET request with query parameters to an API endpoint and verifies that the response contains the expected filtered data based on those parameters.

Test Code - Postman

Postman

pm.test("Verify response contains correct query parameter data", function () {
    const url = pm.request.url;
    pm.expect(url.getQueryString()).to.include("status=active");

    pm.response.to.have.status(200);
    const jsonData = pm.response.json();
    pm.expect(jsonData).to.be.an('array');
    jsonData.forEach(item => {
        pm.expect(item.status).to.eql('active');
    });
});

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts and prepares GET request with query parameter 'status=active'	Postman UI shows request URL with '?status=active' appended	-	PASS
2	Sends GET request to API endpoint with query parameter	Request sent to server with URL including '?status=active'	-	PASS
3	Receives response with HTTP status 200 and JSON body	Response body contains array of objects with 'status' fields	pm.response.to.have.status(200)	PASS
4	Checks that request URL contains query parameter 'status=active'	URL query string is 'status=active'	pm.expect(url.getQueryString()).to.include("status=active")	PASS
5	Verifies each item in response array has 'status' equal to 'active'	All items in JSON array have 'status' field with value 'active'	pm.expect(item.status).to.eql('active') for each item	PASS

Failure Scenario

Failing Condition: Response does not contain expected query parameter or data filtered by it

Execution Trace Quiz - 3 Questions

What does the test verify about the request URL?

A It contains the query parameter 'status=active'

B It uses POST method

C It has no query parameters

D It contains a header named 'status'

Key Result

Always verify that query parameters are correctly included in the request URL and that the API response respects those parameters by filtering data accordingly.
