What is Test-Driven Development in Spring?

Can you explain what Test-Driven Development (TDD) is in the context of Spring?

Test-Driven Development (TDD) is a software development process where you write tests before writing the actual code. In Spring, TDD helps ensure that your components work as expected by creating unit tests for your services and controllers.

What are the benefits of using TDD with Spring?

Using TDD with Spring can lead to better code quality, easier refactoring, and more reliable applications. It encourages you to think about the design and requirements upfront.

How do I get started with TDD in a Spring project?

To get started with TDD in a Spring project, you can set up a Spring Boot application, choose a testing framework like JUnit, and begin by writing your test cases for the desired functionality before implementing the actual code.

Can you give me an example of a simple TDD cycle in Spring?

Sure! First, write a test for a service method that adds two numbers. Then, run the test (it should fail since the method doesn't exist yet). Next, implement the method to make the test pass, and finally, refactor the code if necessary.
