Learn how to write integration tests for Node.js and Express APIs using Jest and Supertest. Test middleware, validation, error handling, and improve coverage with real-world examples.
Most Node.js developers write state-based unit tests and stop there. While those tests are important, they don’t tell the full story. Real-world applications are made of collaborating modules, and if those collaborations break, your app breaks.
In this article, we’ll walk through how to deploy a full-stack Next.js task manager application to an Amazon EC2 instance on AWS. The application uses Amazon Cognito for authentication and includes a simple CRUD system powered by MongoDB.
In this guide, I’ll walk you through how to unit test an Express API in Node.js, using practical examples from a Task Manager project.
