Understanding unit tests
Unit testing is a software testing technique that matters most when you want to ensure that individual units or components of the software are tested in isolation. The goal of unit testing is to validate that each unit of the software performs as expected.
It’s an important aspect of software development, especially in microservices architectures. Node.js, with its asynchronous and event-driven nature, poses unique challenges and opportunities for unit testing. In this context, unit testing involves testing individual functions, methods, or classes within your Node.js application. Let’s cover the importance of unit testing for microservices:
- It ensures code quality: Unit testing helps identify bugs early in the development cycle, ensuring that individual units of code function as intended. This is particularly important in microservices, where services are designed to be small, independent, and modular.
- It facilitates refactoring...
