ScenarioA user wants to ensure that their API returns a 200 status code, indicating a successful request. This function helps verify that the API endpoint is functioning correctly.
Response Body Content Validation
Examplepm.test('Response contains userId', function() { var jsonData = pm.response.json(); pm.expect(jsonData).to.have.property('userId'); });
