A Web service uses only three styles of use: SOAP, REST, and XML-RPC for communication whereas API may be exposed in multiple ways.Web services might not contain all the specifications and cannot perform all the tasks that APIs would perform.All Web services are APIs but not all APIs are Web services.What are the main differences between API and Web Service? In an API testing interview, you could be asked to give some API examples, here are the well-known ones: Google Maps API, Amazon Advertising API, Twitter API, YouTube API, etc. It comprises a number of subroutine definitions, logs, and tools for creating application software. What is an API?Īn API (Application Programming Interface) is a software intermediary that enables two applications to communicate with each other. Definition & Functions of an API (Common Web API Testing interview questions) 1. More than just an API interview, this list of content will also benefit both freshers and senior testers who would like to achieve both general and advanced knowledge in web API testing. The web API testing interview questions below have been collected from the test professionals to help you get ready for a new role. In recent years, many testers will definitely need to face interview questions when applying for a QA job. It becomes a must for software testing projects to ensure product quality. So, don't be afraid of code, you will soon prefer it to codeless solutions.Let's enjoy the Katalon Testing Platform!ĪPI testing has been considered the future of software testing thanks to its advantages in the ability to test for core functionality, time effectiveness, language independence, and GUI integration. They tend to be very fragile, have a lot of useless code and are, in my opinion, only good for very simple scripts and for beginners. And scripts that you wrote yourself would soon be much superior to those made by a web recorder. Well, you don't need to, but it is a very useful skill.
I'm guessing that is what you are now saying: "If a tool can give me the code, why would I need to learn how to code"? This will give you the script code without you having to do any programming. That is the "coders" way: you write the test script in Groovy programming language.Īnother way is to use web recorder (spy/record mode in Katalon Studio, or Katalon Recorder - a browser add-on). Now, you can use Katalon in a variety of ways, one of which is the script mode. If you know Selenium, using Katalon keywords will be simple to learn since they are just a wrapper around Selenium methods.
Katalon Studio is a test automation tool that is based on Selenium.
