Master Angular Unit Testing : From Testing Async Operations, Lifecycle Hooks to services, pipes and directives

What you'll learn

Master Unit Testing in Angular : Students will learn how to write, run, and maintain unit tests for Angular components, services, and pipes.

Effectively Test Asynchronous Code : Learners will understand how to test asynchronous operations, including HTTP requests, Observables and Promises.

Learn to test real world angular application using JASMINE and KARMA.

Student will learn how to do test coverage, mock dependencies and eventually write better code.

Requirements

Basic Understanding of Angular

Basic jаvascript or TypeScript Knowledge

Description

Unlock the full potential of Angular Unit testing with this comprehensive course focused on Advanced Component Testing. Designed for developers who want to build reliable, maintainable, and well-tested Angular applications, this course dives deep into unit testing, dependency injection, async testing, component lifecycle hooks, and more.Throughout the course, you'll learn step-by-step how to set up testing environments, mock services, and test complex components that interact with services and handle asynchronous operations. We'll explore hands-on scenarios to help you understand how to test each component thoroughly, ensuring high code quality and performance. By the end of this course, you'll be fully equipped to write robust test cases for your Angular applications, enabling you to detect issues early and improve development efficiency.Key Topics Covered in this course are:Testing Components with Dependency Injection: Learn how to test components that rely on services, using mock services and testing their interactions.Async Operations: Dive into testing components with asynchronous behavior, including setTimeout functions and async calls.Lifecycle Hooks: Master testing for lifecycle hooks like ngOnInit and ngOnDestroy, ideal for components with initialization logic.Custom Directives and Pipes: Understand how to test custom directives and pipes to enhance the user interface and streamline your code.
