Test-Driven Vue 3: Build Robust Applications with Vitest

Writing frontend code that works is one thing, but writing code that is reliable, maintainable, and easy to refactor is where true software engineering begins. This text-based course introduces you to Vue 3 through the lens of Test-Driven Development (TDD), helping you build high-quality web applications with confidence. By focusing on writing tests before writing implementation code, you will develop a deep understanding of Vue 3 architecture, components, and state management. You will learn how to build features incrementally, minimize bugs, and structure your applications using modern industry standards. What you'll learn: - Understand the core principles of Test-Driven Development (TDD) and how they apply to modern frontend frameworks. - Build responsive Vue 3 components using both the Composition API and Pinia for global state management. - Configure and run tests using Vitest and Testing Library for Vue to simulate user interactions without relying on implementation details. - Implement robust client-side routing using Vue Router and handle internationalization with Vue-i18n. - Apply unit and integration testing strategies to ensure high code quality and smooth refactoring processes. The journey begins with foundational testing concepts and Vue basics before transitioning into building a fully-featured application. Through written explanations, structured code walkthroughs, and practical text-based exercises, you will gradually implement real-world features like routing, localization, and state management. This course is designed for beginners who want to learn Vue 3 and TDD from scratch. No prior experience with testing or Vue is required, though a basic understanding of HTML, CSS, and JavaScript will help you get the most out of the material.
