### Question:
DefaultCustomType { public Object instantiateObject(Object... args) { try { if (instantiationMechanism != null) { return instantiationMechanism.invoke(objectToUseForInstantiation, args); } return constructor.newInstance(args); } catch (IllegalAccessException | IllegalArgumentException | InvocationTargetException | InstantiationException e) { throw new ReflectionUtils.ReflectionException(e); } } DefaultCustomType(Object objectToUseForInstantiation, Method instantiationMechanism);  DefaultCustomType(Class<?> typeToUseForInstantiation, Method instantiationMechanism);  DefaultCustomType(Constructor<?> constructorToInvoke); Object instantiateObject(Object... args); Class<?> getCustomTypeClass();  }### Answer:
@Test(groups = "unit", expectedExceptions = { ReflectionException.class }) public void testInstantiationErrorCondition() throws NoSuchMethodException, SecurityException { Constructor<?> constructorToInvoke = PhoneyClass.class.getConstructor(Integer.class); new DefaultCustomType(constructorToInvoke).instantiateObject("selion"); }
