![]() Also, think about how much time this will reduce, plus the higher level of confidence that the process will run successfully every time you run it. When it comes to automation, it will require a proper setup and some effort to get things ready to go, however, you won’t ever need to run your tests or regression suite manually again. The term ‘API Testing’ is often used, but most of the time this kind of testing is done manually. Delving into this consideration to automate or not would require multiple factors. Although automation itself has a cost, you can calculate your ROI and validate if it’s suitable for your situation or not. What about the cost? Reducing human effort, resources, and time can definitely generate a more favourable return. Lesser amounts of human interaction required and less time taken to get processes completed are examples of many factors being affected by automation. The reduction of effort can come in many shapes. ![]() By automating these processes, you are reducing the amount of effort required, compared to when they were manually performed. From that, you can clearly see why we do automation and its benefits. We will give a quick brief surrounding each topic and provide some resources for your reference.Īs the name itself suggests, automation is the process of transforming something that was previously manually performed, into something that is automatically performed. If you aren’t familiar with any of the mentioned topics, don’t worry. Additionally, we will use Postman when we begin working on the demo. In this blog, we will be talking about API automation within the field of testing. There are so many types of automation, and there are also many fields where automation is involved. Add the following to the Tests window for this request: pm.Nowadays, you would hear a lot about automation and how it’s heavily involved in all aspects of software development now. Now, each request will use dynamic username and email parameters. Replace the username and email in the request body with the dynamic values shown below. The random username and email are set as global variables for the request instance. Pm.t("email", the script above, the current timestamp is used to randomly create usernames and emails for each request that fires. Now you can add requests to your collection. Your new collection is listed on the left sidebar under the Collections tab. You can also add a description for the collection to provide more insight. Then click Create Collection.įill in the name ( Users) of your collection. ![]() To create a new collection, click the Collections tab on the left sidebar of the interface. Postman Collections are normally used to group requests relating to a particular entity. Postman Collections serve as containers for API requests. Your next step is to create a Postman Collection for the user endpoints of the API we are testing. Select the new environment from the dropdown at the top right of the interface.Ĭreating a Postman Collection for API testing Keep them indentical for this tutorial.Ĭlick Save to add the new environment. The value in INITIAL VALUE is duplicated in CURRENT VALUE. Fill in the API base URL with (without a trailing slash). Note: Your Postman UI may look slightly different than the screenshots in this tutorial, but the tools you need will available. Click Create Environment or use the plus icon. Your enviroments will be displayed here if you have any, otherwise, you will have a link to create a new one. Open Postman desktop and select Environments from the left menu bar. Setting up the scope of the environment will help you avoid variables clashing globally or with other environments. To set up an automated testing pipeline for your API tests, you will need to create an environment in Postman. ![]() With everything we need installed and set up, it is time to start the tutorial. You can find the source code here and deploy it following the steps in the post (linked above). It’s a simple Node.js API that consists of endpoints for creating and fetching user accounts. We will be testing the API built and deployed in this post. Postman for Desktop installed on your system.To complete this tutorial, a few things are required: In this tutorial, you will learn how to perform and automate tests against your APIs using Postman’s command-line utility, Newman. You can use Postman as a full-featured collaboration platform for API development and testing. Postman improved the end-to-end testing experience by allowing developers to easily make requests from a user-friendly interface. Testing APIs has come a long way from the time cURL was the only available tool. Automating testing using the Newman orb. ![]()
