Install java, nodejs, and postman for testing our API so you’re ready to dive in. We will also install React developer tools and Redux dev tools to support state management.
Bridge modern JavaScript with backward-compatible code using Bubble and Webpack, and leverage in-IDE feedback from Is linked with Jets for TDD, while Create React App bootstraps a React project.
Configure frontend tests by leveraging Jest in Create React App for assertions, mocking, and test reporting, and extend with React Testing Library to robustly test components rendering HTML elements.
Learn how the React testing library prioritizes testing user behavior over component internals, and install it with npm install --save-dev @testing-library/react, then wait for completion.
Master HTTP requests in Spring Boot through test-driven development by implementing a user registration feature, with tests defining requirements for the rest controller and user controller.
Explore unit tests for small isolated code units and integration tests that validate the whole system by simulating a user sign up across controllers, services, and databases.
Configure Spring Boot tests to run with a dedicated test profile using @ActiveProfiles, enabling test-specific configurations and a separate test database while safeguarding production settings.
Write our integration test with JUnit to verify the user controller's behavior under a valid scenario, using Spring Boot test annotations and a custom test profile on a random port.
Define the test to specify expected behavior by creating a user object. A missing user class triggers a failing test, guiding the next step to build the user model.
Create a user entity by adding a Java class named user in the entities package and update tests to import it, following test-driven development.
Create a user controller in the controllers package and annotate it as a rest controller to handle post requests at /api/1.0/users, with a createUser method to pass tests.
Call createValidUser in the test, then post with the REST template using a URL constant and the user object, verifying the user saves to the database.
Write test logic to verify a user is saved by asserting exactly one user record after a post request, using the user repository interface from Spring Data GPA.
Mark the user class as a JPA entity with a long id primary key and identity-generated value, enabling Spring to map the class to a database table and auto-generate IDs.
Fix the user controller by injecting the user repository and saving the user to the database. Track failing tests as the controller still does not save the user.
Unlock the power of Test-Driven Development (TDD) in this immersive course that guides you through building a complete full-stack application using Spring Boot and React.js. In this hands-on course, you will learn to design, develop, and test a robust sharing platform from scratch, all while following TDD best practices. Whether you are a beginner looking to break into full-stack development or an experienced developer seeking to enhance your testing skills, this course offers a step-by-step approach that ensures you understand every aspect of the process.
We begin by setting up your development environment with essential tools such as Maven, Spring Boot, and IntelliJ for the backend, and Create React App, WebStorm, and Node.js for the frontend. You will explore how to build RESTful APIs, manage databases with Spring Data JPA, and secure your application using Spring Security. On the frontend, you will master React, create reusable components, and manage state with Redux while testing your components using Jest and React Testing Library.
Throughout the course, you will gain invaluable experience in writing tests before code, ensuring that every feature is reliable and maintainable. By the end, you will not only have a fully functional application but also the confidence to apply TDD principles to your own projects, transforming your approach to software development. Enhance your expertise with practical tools, real-world examples, and proven techniques that drive quality development for success today.
