We can set test iterations using Newman with the help of the option –n.Newman's command to list down all options is − newman run –h. Options in Newman is grouped into these categories −UtilityBasic setupRequest optionsOther Misc. OptionsThus complete command to set iterations for two times should be −newman run Collection1.json -n 2Or,newman run Collection1.json --iteration-count 2
There are multiple options parameters and configurations that can be used in a Collection via Newman. The command to obtain a list of options is − newman run –h. Options in Newman can be of types – Utility, Basic setup, Request options and Misc.Utility-h, --help – to display usage details.-v, --version - to display version number.Basic Setup--folder [name of folder] – To point to a particular folder in Collection for execution.-e, --environment [name of file| URL] - To point to an Environment in the form of a JSON file.-d, --iteration-data [file] – To mention a data file to utilize either ...

We can write Assertions in Postman with Chai Assertion Library. Assertions are added in tests to verify if the actual and expected results are similar. In case, they are dissimilar, an Assertion error gets thrown along with the cause of the error.Boolean value of either true or false is returned by an Assertion. In Postman, Assertion is handled by Chai Assertion Library which is developed in JavaScript. It is provided in the Postman application by default.Assertions in Postman are added under the Tests tab. The documentation of the Chai library details are present in the link − https://www.chaijs.com/.Let us create ... Read More
We can get the Response in different formats in Mock Server. A Mock Server is created to avoid sending requests on the real time or production data.

We can add test verifications to the Response obtained from a request with the help of scripts. These scripts are incorporated in the Tests tab. The tests only get executed provided the request is successful.A test developed under the Tests tab is written in JavaScript. Once a request is sent, a Response is obtained along with the test results in the Test Results tab. Tests which have passed are marked in green and the failed ones are marked in red.Add the below JavaScript verifications within the Tests tab −tests["Status Code should be 200"] = responseCode.code === 200 tests["Response time lesser ...
