This article explores API’s and API Testing methods. API (Application Programming Interface) testing is a type of software testing that aims to determine whether the applications are error-free or not. Getting a response to a request is not the only test criteria but to ensure how well the API Performs under pressure. This is one of the reasons why automated testing is necessary with APIs.
What is an API :
API stands for Application Programming Interface. API is an interface between two software components to communicate to each other or it is a script or program that can interact with each other. There are many APIs available and companies provide APIs externally that let users programmatically interact with their services (think Twilio, Stripe, or Plaid).
The most popular API Testing Tools that we will discuss in this article are
