What is Test-Driven Development in Spring Boot?

Test-Driven Development (TDD) is a software development process where you write tests before writing the actual code. In Spring Boot, TDD helps ensure that your application behaves as expected by allowing you to create unit tests and integration tests for your components.

How do I start with TDD in a Spring Boot project?

To start with TDD in a Spring Boot project, first set up your Spring Boot application. Then, create a test class for each component you want to test, using JUnit and Mockito. Write a failing test for a specific functionality, implement the code to pass the test, and then refactor as needed.

What tools do I need for TDD in Spring Boot?

You will need JUnit for unit testing, Mockito for mocking dependencies, and Spring Test for integration testing. Additionally, tools like Maven or Gradle can help manage your project dependencies.

Can you give me an example of a simple test case?

Sure! Here's a simple example: if you have a service method that adds two numbers, you can write a test like this:

@Test
public void testAdd() {
    CalculatorService calculator = new CalculatorService();
    assertEquals(5, calculator.add(2, 3));
}
