Postman web test application8/11/2023 Checking whether the JSON parameter "book_name" exists and whether its value is "Photography". Tests = jsonData.book_name = "Photography" Checking whether the JSON parameter "id" exists and whether its value is 1. Checking whether the Content-type header is present. Tests = postman.getResponseHeader("content-type") Checking whether the response has a status 200. Our next step would be to write tests to validate that response: tests = de = 200 Postman also supports pre-request scripts which are run before an actual request has been sent. For those new to writing test scripts, Postman provides code snippets with examples of validations for response time, response code, etc. One of the great features offered by Postman is the ability to create individual JavaScript test scripts that validate separate API responses. To send a simple request, one only needs to enter it, fill in the necessary headers, select the HTTP method, and the ‘send’ button. Postman offers a simple user-friendly interface. Therefore, we decided to only tell you about Postman this time, as it’s really powerful, and we personally love it here are SteelKiwi. Now, we could, of course, cover all of them in one sitting, but it would just be too much to read. SoapUI is a free tool used to test SOAP and RESTful Web Services. It was developed for sending HTTP requests in a simple and quick way.Ĭurl is a command-line tool used to deliver requests via HTTP, HTTPS, FTP, FTPS, SCP, SFTP, TFTP, LDAP, DAP, DICT, TELNET, FILE, IMAP, POP3, SMTP and RTSP protocols. Postman is a powerful tool used to test web services. There are three widely popular API test-tools: Postman, curl, and SoapUI. Testing APIs is important, because whenever they don’t work properly, major issues may occur in application logic, performance, and security. Presentation, which represents user interface (UI).Īt SteelKiwi, we test APIs to improve application test coverage on the Business Logic layer.Business Logic, which consists of APIs its main purposes are data processing between different layers, logical decision making and application management.Database, where data is extracted from and stored in databases (DB).The majority of mobile apps have three layers to them: API reduces development time and provides developers with access to a number of practical features and services. In other words, it’s a way for different software components to interact with each other. What is an API?Īpplication Programming Interface (or API) is a set of rules, methods, tools and protocols used when building mobile applications. Now, there are many testing automation tools and techniques available, but we’d like to walk you through some of our most favorite ones to help you save time and achieve better results. However, manual API testing is quite a tiresome process, so QA Engineers often choose to automate it whenever appropriate. It’s a part of integration testing, and no quality assurance process is complete without it. API testing helps examine application business logics.
