Question

Given the obvious implementation (without any validation of parameters) of the Coin class m the following UML diagram: Write a suite of JUnit tests that covers every method, statement, and branch in the Coin class. Given the information you have available to you, why could you not write such a JUnit test suite for the Metal class, even though it only has one method? Create a UML class diagram for a Combination class based on the following textual description. A combination lock is either "locked" or "unlocked". A combination lock has an associated combination (i.e., a sequence of 1 or more characters) that cannot be changed. A user can enter a combination: if the combination is correct then the combination lock becomes "unlocked". A user can also "lock" a combination lock.

Explanation / Answer

import org.junit.Test;

import org.junit.Ignore;

import static org.junit.Assert.assertEquals;

public class TestJunit1 {

   String metal=”silver”;

   double weight=20;

   Coin c = new Coin(weight,metal);

  

   @Test

   public void getMetal() {       

      System.out.println("Inside getMetal()");   

      assertEquals(metal, c.getMetal());    

   }

}

JUnit automatically catches exceptions. It considers uncaught exceptions to be errors, which means the given class Metal has redundant code in it.so, could not write Junit Test suit for it..
