Integration Testing

Node.js integration testing validates API endpoints with supertest.

Introduction to Integration Testing

Integration testing is a crucial phase in the software testing lifecycle that involves testing multiple components or systems as a group. In Node.js applications, integration testing ensures that different modules and services interact correctly. This is particularly important for validating API endpoints, where multiple layers of an application stack may be involved.

Why Use Supertest for Integration Testing?

Supertest is a popular Node.js library that simplifies HTTP assertions. It allows you to test HTTP servers seamlessly by sending requests to your endpoints and asserting the responses. This makes it an ideal tool for integration testing in Node.js applications.

With Supertest, you can focus on verifying that your API returns the correct HTTP status codes, headers, and body content without dealing with the lower-level intricacies of HTTP requests.

Setting Up Supertest

Before you begin, ensure you have Node.js and npm installed on your machine. Then, you can set up Supertest in your project by following these steps:
