Introduction
Have you ever worked with any automated testing software tools?
This article is focused on one of these automated testing software tools, i.e., Katalon Studio. Katalon Studio is built on the open-source Selenium and Appium automation frameworks. It has a specialized IDE interface for API, mobile, web, and desktop application testing. Katalon Studio is designed to reuse and create automated test scripts without coding. It allows the execution of automated tests for UI elements. It includes iFrames, pop-ups, and wait time. Linux, macOS, and Microsoft Windows all support launching the tool.
Let's dive into the article to know more about Katalon Studio.
RESTful API
API stands for Application Programming Interface. RESTful API is an API that employs HTTP requests to access and use data. This information will then be used for different purposes. We can use the data for reading, creating, deleting, and updating the resources to make it as per our requirements. For the operations, we can use GET, POST, DELETE, and PUT data types.
Web Application Description Language
Web Application Description Language, or WADL, is an XML description of web services. Those web services are based on HTTP. WADL descriptions are machine-readable. WADL models both the resources that a service offers and their relationships. It simplifies web services reusing. It is language and platform independent. Its goal is to encourage application reuse. WADL was submitted by Sun Microsystems to the W3C (World Wide Web Consortium) on 31 August 2009. But the consortium hasn't standardized it yet. The Web Services Description Language (WSDL) of SOAP is equivalent to WADL in REST. It can be used to describe REST web services.
Import RESTful requests from WADLs
The starting version of Katalon Studio was 7.7.0, which started supporting the importing of WADL files. You can use the WADL file for the creation of RESTful requests.
Today, you will learn how to import the WADL files. The WADL files will help you in creating the Restful request. Let’s see its importation of the WADL file into the Katalon Project.
For importing a RESTful request, perform the steps given below:-
Open or create an API/Web Service project.
Click on the icon Import WADL.
These steps will help you to import from WADL to Katalon. Another way to do this can be via the Tests Explorer panel. Press right-click on Object Repository. Then click on import->From WADL.
Browse your WADL local file in the displayed dialog. Click on OK.
Files are loaded by Katalon studio and accordingly create the RESTful request objects.
Frequently Asked Questions
What is the difference between RESTful and REST API?
There are no differences between RESTful and REST APIs. REST is the set of rules. RESTful refers to an API sticking to those constraints. It can be used in web applications, services, and software.
Are HTTP requests RESTful?
No, HTTP and RESTful are different things. REST is a collection of attributes for a specific architectural style, while HTTP is a well-defined protocol. It helps to exhibit many features of a RESTful system.
Why is the API called RESTful?
API developers can design APIs using several different architectures. APIs that follow the REST architectural style are called REST APIs. Web services that implement REST architecture are called RESTful web services. The term RESTful API generally refers to RESTful web APIs.
What is Katalon Studio used for?
Katalon is used to create and reuse automated test scripts for UI without coding. It allows running automated tests of UI elements. It can be launched on Microsoft Windows, macOS, and Linux.
Is Katalon Studio still free?
The free plan of Katalan Studio is suitable for individuals and small teams. The Premium plan is best for large groups or SMBs who need different test results and have production-grade testing workloads.
What language does Katalon use?
Katalon Studio uses Groovy, a language built on top of Java. It has to load many libraries for parsing test data, test objects, and logging.
