Overview of this book

Do you want to learn how to build robust, reliable, and impressive Angular applications? If yes, then Angular test-driven development is for you! Mastering Angular Test-Driven Development is a comprehensive guide that provides you with essential resources to enhance your skills and deliver high-quality Angular applications. With a practical approach and real-world examples, the book extensively covers TDD concepts, techniques, and tools, going beyond unit testing to explore testing Angular pipes, forms, and reactive programming. In this book, you’ll learn how to validate and manipulate data using pipes, test Angular forms for input validation and user interactions, and handle asynchronous operations with reactive programming. Additionally, you’ll discover end-to-end testing using Protractor, Cypress, and Playwright frameworks, gaining valuable insights into writing robust tests for web applications, navigation, element interaction, and behavior validation. You’ll also understand how to integrate TDD with CI/CD, learning best practices for automating tests, deploying Angular applications, and achieving faster feedback loops. By the end of this book, you’ll be able to successfully implement TDD in your Angular projects with the help of practical examples, best practices, and clear explanations.

Summary

In this chapter, we covered three important topics related to testing in Angular: method stubs and spies, TestBed providers, and handling async operations and complex scenarios.

Firstly, we explored the concept of method stubs and spies, which allowed us to monitor and control the calls to dependencies in our tests. We learned how to create method stubs using Jasmine’s spyOn function, which enabled us to replace a method’s implementation with our own custom behavior. This allowed us to test our code in isolation and ensure that it behaved as expected.

Next, we delved into TestBed providers, which are used to inject mocked dependencies into our tests. We learned how to use the TestBed.configureTestingModule method to configure our test module and provide mocked instances of dependencies. This technique allowed us to control the behavior of dependencies and focus on testing specific scenarios without relying on real implementations.

Lastly, we tackled the...
