How do I set up JUnit in Eclipse?

To set up JUnit in Eclipse, first, ensure you have Eclipse IDE installed. Then, follow these steps: 1. Go to 'Help' > 'Eclipse Marketplace'. 2. Search for 'JUnit' and install it if it's not already included. 3. Create a new Java project or open an existing one. 4. Right-click on your project, select 'Build Path' > 'Add Libraries', and choose 'JUnit'. 5. Select the JUnit version you want to use and click 'Finish'. You’re all set!

What version of JUnit should I use?

It depends on your project requirements. JUnit 4 is widely used and stable, while JUnit 5 offers more features and flexibility. If you're starting a new project, I recommend using JUnit 5.

Can you show me how to write a simple test case?

Sure! Here’s a simple example: 1. Create a new class in your project. 2. Annotate it with @Test. 3. Write a method that performs the test. For example:

import static org.junit.jupiter.api.Assertions.*;
import org.junit.jupiter.api.Test;

public class MyTest {
    @Test
    public void testAddition() {
        assertEquals(2, 1 + 1);
    }
}
``` This tests that 1 + 1 equals 2.
