      Description

      A test would look as follows:

      PigServer pigServer = new PigServer(ExecType.LOCAL);
      TupleFactory tf = TupleFactory.getInstance();
      Data data = Storage.resetData(pigServer.getPigContext());
      data.set("foo", Arrays.asList(
          tf.newTuple("a"),
          tf.newTuple("b"),
          tf.newTuple("c")
          ));
      
      pigServer.registerQuery("A = LOAD 'foo' USING mock.Storage();");
      // some complex script to test
      pigServer.registerQuery("STORE A INTO 'bar' USING mock.Storage();");
      
      Iterator<Tuple> out = data.get("bar").iterator();
      assertEquals("a", out.next().get(0));
      assertEquals("b", out.next().get(0));
      assertEquals("c", out.next().get(0));
