![]() ![]() In this test we have an assert that verifies that the status code is 200 and also a loop to store information about a certain ship of all the returned ones in an environment variable. On the right side we have a series of pieces of code that help the user to create tests. The second part of creating a request is the Tests section, designed to create asserts that verify that the information returned by the server is what we were expecting and values can also be assigned to new environment or global variables to use later. For example: ĪPI: The full address would be /api/starships, but since we already save /api in the host environment variable we just have to write to use it. Method: It can be GET, POST, PUT, DELETE. In this example we try to get a list of spaceships, so in the screenshot you can see: Then we can create a request, which will look something like this: Postman allows you to create collections to store requests, so the first thing we need is to create a collection, providing its name (required) and a description. This API does not need the user to authenticate, but if it did, we could save the username and password in the environment. The first thing we have to do before starting to create tests is to prepare an environment for the server in which the tests will be run. To create an environment we go to Manage environments → Add. Then we can start adding key-value pairs corresponding to variables that we will use multiple times in requests.Īs an example, I have chosen the following API to explain how it works: /api , so we are going to save it in a variable that we will call host: "The main objective of Postman is to help build APIs quickly allowing the agile creation of requests and workflows through collections" Environment The first program that we are going to use to achieve test automation is Postman, which can be defined as follows: The test automation is to use a program to control the execution of tests and check if the results are what we were expecting. To explain how to automate tests on an API, three programs will be needed: Postman, Newman and Jenkins. Test automation for an API: Postman, Newman and Jenkins What is test automation? Step11 − After the Build has completed, click on the Console Output link in the sidebar from the Build details screen to get the details of the Newman output.Posted on 2 of August of 2016. Step10 − Click on Build Now from the left of the Jenkins application. The exit code means that Newman execution shall get stopped if any errors are encountered. Step9 − Add the below command in the Execute Shell edit box under the Build tab. Select the option Execute shell from the Add build step up dropdown. Step8 − Click on the Source Code Management tab and move to the Build section. Step7 − Choose the option Freestyle Project, enter a project name then click on the OK button. Step6 − Once Jenkins is up and running, it provides an interface: Then click on New Item in the top left corner of the Postman application. ![]() (The file name should always be in inverted quotes). Step5 − Open Terminal, navigate to the directory where the Collection is stored. Step4 − We have to install Newman with the help of the command: npm install -g newman. ![]() Step3 − The npm is allocated with Nodejs so once we download the Nodejs, the npm gets downloaded automatically. For installation of Nodejs can be done from the below link − Step2 − We have to install npm and Nodejs. The steps to perform this task is discussed in details in the below link − Step1 − We have to complete the installation and configuration of Jenkins. To integrate Newman and Jenkins, we have to follow the below steps − Newman is used to verify and execute a Collection. We can integrate Postman with Newman and Jenkins. ![]()
