Estoy tratando de simular una función de obtención de axios pero obtengo TypeError: moduleName.startsWith is not a function cuando se burla de "axios". ¿Cuál sería la forma correcta de burlarse?

Error:

 FAIL src/tests/Sample.test.jsx ● Test suite failed to run TypeError: moduleName.startsWith is not a function 5 | import { backendUrl } from "../helper/constants" 6 | describe("test useEffect and axios", () => { > 7 | const mockGet = jest.mock(axios.get)

Muestra.prueba.jsx

 import { mount } from "enzyme" import { screen, render, act } from "@testing-library/react" import Sample from "../pages/Sample" import axios from "axios" import { backendUrl } from "../helper/constants" describe("test useEffect and axios", () => { const mockGet = jest.mock(axios.get) // THROWS ERROR HERE let wrapper it("should call axios", async () => { await act(async () => { mockGet.mockImplementationOnce(() => Promise.resolve({})) wrapper = mount(<Sample />) }) wrapper.update() await expect(mockGet).toHaveBeenCalledWith(backendUrl) }) })

Muestra.jsx

 import axios from "axios" import { useState, useEffect } from "react" import { backendUrl } from "../helper/constants" const Sample = () =>{ const [pets, setPets] = useState([]) useEffect(() => axios.get(backendUrl) .then(({data}) =>setPets(data.entries)) .catch((err)=>console.log(err)), []) return ( <> <p>I h8 all of you</p> {pets.map((e, i) =><h2 key={i}>{e.Link}</h2>)} </> ) } export default Sample
