title: Access a List in JUnit Test Case
body: <p>I have this ParkingLot.java</p>
  
  <pre><code> public class ParkingLot {
  
  private final int size;
  private Car[] slots = null;
  
  List&lt;String&gt; list = new ArrayList&lt;String&gt;();
  
  public ParkingLot(int size) {
      this.size = size;
      this.slots = new Car[size];
  }
  
  public List licenseWithAParticularColour(String colour) {
      for (int i = 0; i &lt; slots.length; i++) {
          if (slots[i].getColour() == colour) {
              System.out.println(slots[i].getLicense());
              list.add(slots[i].getLicense());
              return list;
          }
      }
      return null;
  }
  </code></pre>
  
  <p>}</p>
  
  <p>I have created a ParkingLotTest.java as follows</p>
  
  <pre><code>public class ParkingLotTest {
  
  private Car car1;
  private Car car2;
  private Car car3;
  
  private Ticket ticket1;
  private Ticket ticket2;
  private Ticket ticket3;
  
  private ParkingLot parkingLot;
  
  private List&lt;String&gt; list = new ArrayList&lt;String&gt;();
  
  @Before
  public void intializeTestEnvironment() throws Exception {
      this.car1 = new Car("1234", "White");
      this.car2 = new Car("4567", "Black");
      this.car3 = new Car("0000", "Red");
  
      this.parkingLot = new ParkingLot(2);
  
      this.ticket1 = parkingLot.park(car1);
      this.ticket2 = parkingLot.park(car2);
      this.ticket3 = parkingLot.park(car3);
      this.list = parkingLot.list;
  
  
  }
  
  @Test
  public void shouldGetLicensesWithAParticularColour() throws Exception {
      assertEquals(, parkingLot.licenseWithAParticularColour("White"));
  
  }
  </code></pre>
  
  <p>}</p>
  
  <p>In the above Test Case, I want to check that the List is filled with the correct Licenses. 
  1. How do i create a field in the ParkingLotTest.java so that the List in the first class is same as list in the second class file.</p>
