Katalon is an end to end testing framework built on top of selenium and the main feature of Katalon studio is that is can with easily used by Tester who does not have much knowledge of programming language. It has a user interface that is easy to use and test.
The best part of using Katalon Studio is that the tester does not require much knowledge of a programming language. Other Selenium based framework requires a good knowledge of a coding language and thus is a little complicated than Katalon Studios. With selenium, one must use the IDE like eclipse to import Selenium libraries and also must install frameworks like TestNG, Junit etc. But with Katalon we can directly install it and start working on the test case without any other installation.
Katalon Studio requires minimum installation compared to Selenium and other selenium based framework. They need installation of IDE, Java SDK, Installation of API of preferred language and few more things. But with Katalon all these things are not needed to be downloaded separately as the package has all. Katalon studio is easy to learn and use because of it’s UI.
Katalon Studio is released with pre-defined sets of commonly used keywords or actions, users will find them enough to start implementing most test cases, but if they have more advanced or specific needs they still have a way to create custom keywords for their projects. Custom keywords are an extension of built-in keywords. They can be used in the same way as built-in keywords and can be shared between users.
Selenium and Appium users have to build common and reusable actions on their own in forms of programming functions.
With time Katalon is becoming more and more popular and a large number of job opportunities are expected in this field. Here is a graph that shows the growing popularity of this tool.
