This course is designed to teach you how to manage states in Angular using the powerful NgRx library.

You’ll learn the fundamentals of state management and how it can be implemented in an Angular application using NgRx. Next, you’ll learn how to use the NgRx store, actions, reducers, and selectors to manage the application states and handle complex data. You’ll also learn how to handle side effects and asynchronous operations in an Angular application.

Throughout the course, you’ll gain hands-on experience in implementing state management using interactive projects. You’ll learn best practices and design patterns for state management in Angular and how to structure the state of an application using NgRx. Additionally, you’ll learn how to write unit test cases for NgRx features.

By the end of the course, you’ll be able to implement and debug states in an Angular application. You’ll be able to create more scalable, maintainable, and testable Angular applications that can handle complex states and data.

Mastering State Management with Angular and NgRx

In this chapter, we learned how to unit test the various NgRx features. We wrote unit test code for the reducers, selectors, and effects.

## What is unit testing?

Before deploying our code to production, we must ensure that all of our application's components are functioning properly. We learned how to ensure this by dividing our code into smaller chunks called units and testing the functionality of each unit separately. A unit can be a function, module, or object. This type of testing is known as unit testing in software development.
