If you want to learn Unit Testing and End-to-End (e2e) Testing in NestJS using Jest, then this course is for you. NestJS is one of the most powerful frameworks for building scalable backend applications. But writing code is not enough — proper testing ensures your application is reliable and production-ready.
In this course, you will learn how to write unit tests for controllers, services, and modules and how to perform end-to-end testing of APIs using Jest. We will use TypeScript and NestJS’s built-in Testing Module to mock dependencies, test business logic, and verify complete API behavior. By the end of this course, you will be able to confidently write clean, maintainable, and production-ready tests for your NestJS applications.
