Answer 1

I have modified the above code. Instead of taking input from the user, I have sent "answer" as an argument.You have to execute all the below files in Eclipse. First You need to create a "testing" package .In this package you have to create all the following files.

Essay.java

package testing;

public class Essay
{

    private String question;
    private String answer;

    public Essay(String q)
    {

        this.question = q;

    }

//This function returns question text
    public String getQuestionText()
    {
        return question;
    }

//This function takes answer from user
    public void answer(String userAnswer)
    {
           this.answer=userAnswer;
    }

    public String getAnswer()
    {

     

        if(answer.length() <=140)
        {

            return answer;

        }
        else
        {

            return "Invalid Answer";

        }

    }

}

questionTest.java

package testing;

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

public class questionTest {

   @Test
   void test()
   {
       Essay test1=new Essay("how are you?");
       String q=test1.getQuestionText();
       assertEquals("how are you?",q);
      
   }

}

answerTest.java

package testing;

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

public class answerTest {

   @Test
   void test()
   {
       Essay test2=new Essay("How are you?");
       test2.answer("I am Fine!");
       String q1=test2.getAnswer();
       assertEquals("I am Fine!",q1);
   }

}
