Spring Boot and React Full-Stack Development with TDD

Building full-stack applications can feel overwhelming when backend and frontend systems fail to connect or break during updates. Applying Test-Driven Development (TDD) ensures your code remains reliable, maintainable, and easy to refactor as your application grows. In this text-based course, you will learn how to build a secure, fully functional single-page application from scratch. By writing tests first using JUnit for the Spring Boot backend and Jest with React Testing Library for the frontend, you will gain the confidence to implement new features and refactor code without breaking existing functionality. What you'll learn: - Understand the core principles of Test-Driven Development (TDD) and how to write effective unit and integration tests. - Build a secure RESTful API using Spring Boot, Spring Data JPA, and modern Spring Security configurations. - Create a responsive frontend using React functional components, modern Hooks, and React Router. - Apply state management principles to handle application data seamlessly between the frontend and backend. - Configure robust validation, error handling, and internationalization (i18n) on both the client and server sides. - Practice refactoring code with confidence, relying on your test suite to verify application behavior at every step. The course begins with foundational concepts of TDD and full-stack architecture, gradually guiding you through the step-by-step implementation of backend services and frontend components. Through detailed written explanations and clear code snippets, you will build a complete, tested application one feature at a time. This course is designed for beginner developers, software engineering students, and backend or frontend programmers looking to transition into full-stack development using TDD. No prior experience with test-driven development is required, though a basic understanding of Java and JavaScript is helpful.
