Katalon Studio is a free automation testing tool that supports API, web, and mobile testing, built on open-source frameworks like Selenium and Appium. API testing is crucial for ensuring functionality, reliability, performance, and security in software applications, and is performed at the business logic layer. Advantages of API testing include cost reduction, time efficiency, and the ability to identify bugs early, leading to better overall test coverage.

5. Introduction To API Testing
● What is API testing?
● Where is API testing performed?
● Why do we need to perform API testing?

6. What is API testing?
What is an API?
API is an acronym and it stands for Application Programming
Interface. API is a set of routines, protocols, and tools for building
Software Applications. APIs specify how one software program should
interact with other software programs.
API testing is a type of software testing that involves testing
application programming interfaces (APIs) directly and as part of
integration testing to determine if they meet expectations for
functionality, reliability, performance, and security.

7. Where is API testing performed?
API Testing is performed at the
most critical layer, the Business
Layer, where business logic
processing is carried out, and all
transactions between User
Interface and Database happen.

8. Advantages of API testing
●API Testing is time effective when compared to GUI Testing. API test
automation requires less code so it can provide faster and better test
coverage.
●API Testing helps us to reduce the testing cost. With API Testing we can
find minor bugs before the GUI Testing. These minor bugs will become
bigger during the GUI Testing. So finding those bugs in the API Testing
will be cost effective to the Company.
●API Testing is language independent.
●API Testing is quite helpful in testing Core Functionality. We can test the
APIs without a user interface. In GUI Testing, we need to wait until the
application is available to test the core functionalities.
●API Testing helps us to reduce the risks.
