API Test

API Testing helps test your postman collection or automtion code in restassured or karate. Let’s walkthrough how to do it


  • API testing is a type of software testing that analyzes an application program interface (API) to verify that it fulfills its expected functionality, security, performance and reliability.
  • APIs are set of rules and protocols that allow different software applications to communicate and interact with each other.

What is API Test?

  1. API testing, also known as Application Programming Interface testing, is a type of software testing that focuses on validating the functionality and reliability of APIs (Application Programming Interfaces).
  2. API testing focuses on analyzing the application’s business logic as well as security and data responses.

Why to use API Test?

  1. Postman Collections are a group of saved requests. Every request you send in Postman appears under the History tab of the sidebar. On a small scale, reusing requests through the history section is convenient. As your Postman usage grows, it can be time-consuming to find a particular request in your history. Instead of scrolling through your history section, you can save all your requests as a group for easier access.
  2. With the help of aiTest, user can test this collection with the desired workload provided in the configurations while creating the tests.


The benefits of API testing in aiTest include
