   Yo prefiero algo asi como:
   
   ------ HelloWorldTest.java
   import org.junit.Test;
   import org.mockito.Mockito;
   import java.io.PrintStream;
   
   public class HelloWorldTest {
   
   @Test
   public void test_hello_world_is_printed() {
   PrintStream output = Mockito.mock(PrintStream.class);
   HelloWorld hw = new HelloWorld(output);
   hw.sayPhrase();
   Mockito.verify(output).println("Hello world!");
   }
   }
   ------- HelloWorld.java
   import java.io.PrintStream;
   
   private class HelloWorld {
   
   private final PrintStream output;
   
   public HelloWorld(final PrintStream output) {
   this.output = output;
   }
   
   public void sayPhrase() {
   output.println("Hello world!");
   }
   
   public static void main(String[] args) {
   HelloWorld hw = new HelloWorld(System.out);
   hw.sayPhrase();
   }
   }
