The "normal" way is to re-instantiate things in your "setUp" method. However, if you have a real object that is expensive to construct for some reason, you could do something like this:

public class MyTests {

  private static MyBigWarehouse realWarehouse = new MyBigWarehouse();
  private MyBigWarehouse warehouseSpy;

  @Before
  public void setUp() {
    warehouseSpy = spy(realWarehouse); // same real object - brand new spy!
    doReturn(false).when(wareHouseSpy).isSomethingMissing();
  }

  @Test
  ...

  @Test

}
