I am running a test at the moment and these 2 lines are missing on my coverage

hideAddViewModal = () => 
this.setState(showAddViewModal: false)

I wrote the following test, but not sure why is not picking up.
Am I missing anything?
Mounting my component using Enzyme and Jest

it ('Test hideAddViewModal method ',() => 
 wrapper.setState(
 showAddViewModal: false,
 );
wrapper.update();
expect(wrapper.instance().hideAddViewModal('test')).toEqual()
expect(wrapper.state('hideAddViewModal')).toBeFalsy();
);

Error: wrapper.instance(...).hideAddViewModal is not a function

  how are you declaring the wrapper? are you using shallow render or mounting the component with enzyme?

  Please include in your question the code that is declaring the wrapper and include more information about the component itself. Keep in mind that from React 16 and above, stateless components will always return null.
