Testing in NodeJS
NodeJS is a JavaScript runtime environment, and testing it involves ensuring the correctness of server-side logic, APIs, and integration with other components.
Test cases might include verifying business logic, testing API endpoints, and assessing performance.
Tools like Mocha, Chai, Supertest, and Sinon are commonly used for testing Node.js applications.
In addition to these component-specific tests, integration testing is essential in MERN applications to validate interactions between different layers of the stack (e.g., testing API endpoints that interact with MongoDB using Express.js and NodeJS).
Introduction to Testing in MERN
Testing in MERN (MongoDB, ExpressJS, React, NodeJS) applications is important for ensuring the reliability, functionality, and stability of your software. Testing helps identify bugs early in the development process, maintain code quality, and build confidence in your application’s behavior.
In this article, you will be walking through the basics of testing in MERN.
