Welcome to the next stage in mastering Test Driven Development (TDD) in Java, where we will focus on setting up a robust testing environment. As you have learned through the TDD process, the Red-Green-Refactor cycle involves writing a failing test, implementing just enough code to pass it, and refining the implementation.

In this lesson, we will set up the necessary tools for testing with JUnit, guiding you on how to create an efficient Java testing environment that complements the TDD cycle.

JUnit is a popular and widely used testing framework for Java. Now, let's dive into setting up our testing environment in a systematic way.

To start using JUnit with Java, you'll need to create a test project within your environment. This can be accomplished using Gradle, a powerful build tool for Java, by following these steps:

1. Create a new Gradle project:

2. Add the JUnit dependency to your build.gradle file:

3. Sync your Gradle project:
