Test functions with Jest and Enzyme?

Question

How can I test this function with Jest and Enzyme?

addProducts = id => {
   toast.success("Product added", {
      position: toast.POSITION.TOP_RIGHT
   });
   history.push(`/product/${id}`);
};

I was using this bit of code, but it wasn’t enough ...

it("Must return added addProduct with success message", () => {
   const componente = shallow(<AddProduct />);

   const spy = jest.spyOn(wrapper.instance(), "addProducts");

   expect(spy).toBeTruthy();
});
