### Question:
FunctionalBindingParameterInvoker implements BindingParameterInvoker { public static FunctionalBindingParameterInvoker create( Type originalType, BindingParameter bindingParameter) { try { FunctionalBindingParameterInvoker invokerGroup = new FunctionalBindingParameterInvoker(originalType, bindingParameter); return invokerGroup; } catch (UnreachablePropertyException e) { throw new BindingException("Parameter '" + bindingParameter + "' can't be readable", e); } } private  FunctionalBindingParameterInvoker(Type originalType, BindingParameter bindingParameter); static FunctionalBindingParameterInvoker create(
      Type originalType, BindingParameter bindingParameter); @Override Type getTargetType(); @Override Object invoke(Object obj); @Override BindingParameter getBindingParameter();  }### Answer:
@Test public void testBindingException4() throws Exception { thrown.expect(BindingException.class); thrown.expectMessage("Parameter ':user.userBag.ite' can't be readable; " + "caused by: There is no getter/setter for property named 'ite' in 'class org.jfaster.mango.binding.FunctionalBindingParameterInvokerTest$UserBag'"); FunctionalBindingParameterInvoker.create(User.class, BindingParameter.create("user", "userBag.ite", null)); }
