===== Minta =====

A példaprogramban metódus tesztelés is van.

<code java src/App.java>
public class App {    
    public static void main(String[] args) throws Exception {
        new MainController();
    }
}
</code>


<code java src/models/FileHandler.java>
import java.util.ArrayList;

public class FileHandler {
    ArrayList<String> wordList;
    public void readFile() {
        
    }
}
</code>


<code java test/RhombusTest.java>
import static org.junit.jupiter.api.Assertions.assertTrue;
