Course Title: JavaScript Unit Testing - The Practical Guide

Instructor: Academind by Maximilian Schwarzmüller

Overview: Automated testing is a key concept in modern (web) development, yet it can be daunting for many developers. This course demystifies the process of writing unit and integration tests for JavaScript projects using Vitest & Jest. We'll dive into the practical aspects of testing from the ground up, ensuring you understand not just how to write tests but also why they are crucial for your projects.

What You'll Learn:

• The Basics of Testing: We'll start by breaking down what "testing" and "automated testing" entail, and why they're essential for robust applications.
• Unit Testing Explained: Understand the role of unit tests in the development process and their importance in isolating and testing individual units of code.
• Essential Tools & Setup: Discover the tools you need to start writing automated unit tests for your JavaScript projects.
• Writing Unit Tests: Learn how to effectively write unit tests that are maintainable and provide true insights into your code's behavior.
• Diving into Integration Testing: Expand your testing skills with an introduction to integration tests and understand their place in the larger context of application testing.
• Assertions Mastery: Master formulating different expectations (assertions) to validate the outcomes of your code.
• Best Practices for Writing Tests: Follow industry patterns and practices that will lead to well-structured and efficient test suites.
• Handling Asynchronous Code: Learn strategies for testing both synchronous and asynchronous JavaScript code.
• Managing Side Effects: Utilize spies & mocks effectively to deal with side effects in your tests, ensuring that external dependencies don't interfere with test accuracy.
• Real-World Application: Apply all the concepts learned through practical examples and projects provided within the course.

Course Highlights:

• Hands-On Learning: This course is designed to be hands-on, ensuring you learn by doing and not just in theory.
