How do I write the JUnit tests for the following interface?
Question.java
package cs5004.questionnaire;
/**
* Represents the Question interface outlining the methods for a standard Question.
*/
public interface Question
{
/**
* Retrieves the question in the form of a String from a given object.
*
* @returns the question in the form of a String.
*/
public abstract String getPrompt();
/**
* Retrieves the boolean requirement of whether or not the question is required.
*
* @returns the boolean of the requirement.
*/
public abstract boolean isRequired();
/**
* Retrieves the answer that the user answered the question with.
*
* @returns the answer in the form of a string.
*/
public abstract String getAnswer();
/**
* Copies or duplicates the Question object in addition to its associated data.
*
* @returns a copy of the Question object.
*/
public abstract Question copy();
/**
* Allows the user to answer the question in which a String called answer is given.
* @param answer in the form of a String.
* @returns a copy of the Question object.
*/
public abstract void answer(String answer);
}
