Introduction to API Testing

API Testing Strategy


Test Automation



  • Software Testing Knowledge


API testing is a type of software testing that analyzes an application program interface (API) to verify it fulfills its expected functionality, security, performance, and reliability.

We have many advantages for learning API Testing, some of them are:

  • Improved test coverage
  • Greater test stability
  • Reduced testing costs
  • API test automation requires less code than automated GUI tests, resulting in faster testing and a lower overall cost.

Through this course; the audience would get a detailed insight into how to test APIs. In this course, all information is presented in an easy straightforward way so any non-tech person can start with it to have the proper guidance about API testing, also any software engineer who is looking to enrich his/her knowledge related to API Testing is the right course for you.

What you’ll learn:

We will have a walkthrough of what is an API and how can we see the web and mobile APIs.
A tour of Postman (Postman is an API platform for building and using APIs) and the strategy of testing APIs in this tool. Lastly, we will discuss how to automate a collection of APIs using the Postman tool.

Are there any course requirements or prerequisites?
