Introduction
In the rapidly evolving world of software development, Application Programming Interfaces (APIs) play a crucial role in enabling communication between different software systems. API testing, therefore, becomes essential to ensure that these interfaces work as expected, providing reliability, performance, and security.
What is API Testing?
API testing is a type of software testing that involves sending calls to the APIs and comparing the responses to expected results. This testing is crucial for verifying the functionality, reliability, performance, and security of the APIs. By conducting API testing, developers can identify issues early in the development lifecycle, reducing the cost and time required for fixing bugs later on.
