What value to pass to the method with SyntheticEvent?

Question

React

I need to test a method in a component:

showForm = (event: SyntheticEvent<*>) => {
    event.preventDefault();
    this.setState(() => ({ formVisible: true }));
  }

It works when you click on the "a" tag.
I am using jest and enzyme. What needs to be passed to the method call for it to work correctly?

it('check showForm method', () => {
    const wrapper = shallow(<Contacts {...props} />);
    wrapper.setState({ formVisible: false });
    wrapper.instance().showForm({ SynteticEvent });
    expect(wrapper.state('formVisible')).toEqual(true);
  });

Answer 1

const syntheticEvent = (target) => ({
  target,
  reventDefault: jest.fn(),
  stopPropagation: jest.fn(),
});

const event = syntheticEvent();
