![]() ![]() The next category is API clients that come with a graphical user interface. It’s an HTTPie wrapper around cURL-it can match cURL’s performance and feature parity while maintaining HTTPie’s ease of use. CurlieĬurlie tries to hit the sweet spot between cURL and HTTPie. HTTPie has a major drawback: its often subpar performance can hinder executing hundreds of automated tests. While there aren’t many online guides, the client is significantly easier to use. HTTPie aims to provide a more user-friendly interface than cURL’s clunky one. ![]() It’s open source and free as in free beer, but it doesn’t come preinstalled on modern operating systems. HTTPie is a more up-to-date alternative to cURL. ![]() But since it’s a de facto standard Linux software, it remains popular, with countless guides and tutorials offered online (there are over 40,000 questions with the cURL tag just on Stack Overflow). It’s a battle-tested tool that has displayed good performance characteristics over the years, and it can handle running huge API test suites.ĬURL’s main downsides are its age and cumbersome interface. It comes preinstalled on all major Linux distributions and even macOS it’s also free and open source. cURLĬURL is the most widely used Linux CLI API client. They run in the command line and can easily integrate with other tools, making easy work out of automation and CI/CD integration. If authentication is successful, the API shows a 200/OK response.Let’s start with command line interface (CLI) clients.Click the Authorization tab and add authorization tokens and credentials as per requirements.Wait for the downloading and installation process to complete.Run Google Chrome and go to More Tools > Extensions.To use Postman, you must configure it in your chrome browser using below steps: Installing POSTMAN One of the available application to perform API testing is using Postman. API testing requires less code and thus provides better and faster test coverage than automated GUI tests. In other words, we can also say that an API is a collection of software functions and procedures that can be executed by other software applicationsĪn API does not have any UI, therefore API testing is performed at the message layer. REST messages often accepts the form either in form of XML, or JavaScript Object Notation (JSON).īefore starting with the installation and usage process, let me first give you a brief overview about the API testing What is APIĪPI (Application Programming Interface) testing is a software testing which involves testing application programming interfaces to determine if they are meeting the expectations of the desired functionality.For sending and receiving messages, it involves using HTTP methods, and it does not require a strict message definition, unlike Web services.REST also permits communication between computers with each other over a network.In REST API interactions are made via HTTP protocol. Itâs an arrangement of functions on which the testers performs requests and receive responses.The objective of API testing is to confirm right execution and blunder treatment of the part preceding its coordination into an application. It testing regards the segment under test as a black box. ![]() It can be executed by composing capacity brings in the system.ĪPI testing utilizes programming to send calls to the API and get the yield. With APIs, applications converse with each other with no client learning or intervention. It is a software to software interface, not a user interface. API stands for Application Programming Interface. ![]()
