How to properly test a function and mock which calls the function?

Question

React

The original function is here openFormNewItemEdit
I want to check that actionopenFormNewItemEdit received data and it is equal to the date in the test?
I don’t quite understand how to lock correctly
and can it be more correct to take snapshots of the results of such functions?

let props = {
        data: {
            name: "Мои заметки № 1",
            text: "Мои заметки № 1",
            time: 1636283818894,
            key: "-Mnu6P7dMJTeVv8VESLh",
            keychapter: "0"
        },
        keychapter: "0",
        keyitem: "-Mnu6P7dMJTeVv8VESLh",
        index: 1,
        attrdata: "all",
        del: false,
    }
let actionopenFormNewItemEdit = jest.fn(data, dispatch){ return data};
или так надо сделать 
let actionopenFormNewItemEdit = () => { return { name: props.data.name, text: props.data.text, activ: true, keychapter: props.keychapter, keyitem: props.keyitem } };
expect(instance.openFormNewItemEdit()).toBe({ name: props.data.name, text: props.data.text, activ: true, keychapter: props.keychapter, keyitem: props.keyitem });

openFormNewItemEdit = () => {
        let data = { name: this.props.data.name, text: this.props.data.text, activ: true, keychapter: this.props.keychapter, keyitem: this.props.keyitem };
        actionopenFormNewItemEdit(data, this.props.dispatch);
    }

and so I try it doesn't work

Matcher error: received value must be a mock or spy function

Received has type: function
Received has value: [Function actionopenFormNewItemEdit]

test('TaskItemContainer openFormNewItemEdit', () => {
        instance.openFormNewItemEdit();
        expect(actionopenFormNewItemEdit).toBeCalled();
    });
