Unit testing and remote debugging

In microservices architecture, unit testing and remote debugging play a crucial role while developing microservices.

Unit testing

Unit testing is a software testing technique that verifies the functionality and quality of individual units or components of a software system. A unit can be a function, a method, a class, or any other isolated piece of code. Unit testing is usually performed by developers using automated tools or frameworks, and it helps with identifying and fixing bugs early in the development process.

Here are some key principles of unit testing:
