Testing react component methods with HOC

As in the topic I would like to test react component methods that have HOC.

Usually I did it this way:

   describe("component method", () => {
    it("returns with null or undefined value", () => {
        const wrapper = shallow(<Component />);
        expect(wrapper.instance().methodName());
    });
});

but right now I have component that needs store so I am trying to do it this way:

 describe("component method", () => {
    it("returns with null or undefined value", () => {
        const wrapper = shallow(<Component store={store} />);
        expect(wrapper.instance().methodName());
    });
});

of course store is defined:

const mockStore = configureMockStore();
let store;

but I get error

TypeError: wrapper.instance(...).methodName is not a function

Could it be because my component is wrapped like this?

export default withSocket(Component);

If yes how can I solve it?
