Question

how would you write a junit test for this 
import java.io.File;

public class CheckEmptyDirectoryExample
{
    public static void main(String[] args)
    {   

 
File file = new File("C:\\folder");
                
        if(file.isDirectory()){
                        
                if(file.list().length>0){
                                
                        System.out.println("Directory is not empty!");
                                
                }else{
                                
                        System.out.println("Directory is empty!");
                                
                }
                        
        }else{
                        
                System.out.println("This is not a directory");
                        
        }
    }

Answer 1

we can't write the Junit for the above code as it is not returning anything and we are not able to pass anything as it is harcoded directly

first we need to change the code to take the path from the command line arguments than only we can write the test cases for it
