如何在不同的测试组中测试我的API调用？

我先从react-testing-library开始，然后我试图测试API调用。我有两套，一套用于成功请求，另一套用于错误请求。

import React from "react";
import { render, waitForElementToBeRemoved } from "@testing-library/react";
import user from "@testing-library/user-event";
import App from "./App";
import { getUser } from "./serviceGithub";

jest.mock("./serviceGithub");

//Mock data for success and error, Im using the github api
const dataSuccess = {
    id: "2231231",
    name: "enzouu",
};

const dataError = {
    message: "not found",
};

const renderInit = () => {
    const utils = render(<App />);
    const inputUser = utils.getByPlaceholderText("ingrese usuario", {
        exact: false,
    });
    const buttonSearch = utils.getByRole("button", { name: /buscar/i });

    return { utils, buttonSearch, inputUser };
};

test("should success request to api", async () => {
    getUser.mockResolvedValue([dataSuccess]);
    const { utils, buttonSearch, inputUser } = renderInit();
    expect(utils.getByText(/esperando/i)).toBeInTheDocument();
    expect(buttonSearch).toBeDisabled();
    user.type(inputUser, "enzzoperez");
    expect(buttonSearch).toBeEnabled();
    user.click(buttonSearch);
    await waitForElementToBeRemoved(() =>
        utils.getByText("cargando", { exact: false })
    );
    expect(getUser).toHaveBeenCalledWith("enzzoperez");
    expect(getUser).toHaveBeenCalledTimes(1);
    expect(utils.getByText("enzouu", { exact: false })).toBeInTheDocument();
});

test("should error request to api", async () => {
    getUser.mockResolvedValue(dataError)
    const { utils, buttonSearch, inputUser } = renderInit();
    expect(buttonSearch).toBeDisabled();
    user.type(inputUser, "i4334jnrkni43");
    expect(buttonSearch).toBeEnabled();
    user.click(buttonSearch)
    await waitForElementToBeRemoved(()=>utils.getByText(/cargando/i))
    expect(getUser).toHaveBeenCalledWith('i4334jnrkni43')
    expect(getUser).toHaveBeenCalledTimes(1)
});

这里的问题是，在第二次测试中，最后一行expect(getUser).toHaveBeenCalledTimes(1)由于getUser调用2次而出错，但是如果我评论第一个测试，则第二次通过。

那么，我应该如何测试这种情况？我可以进行测试的方式还可以吗？

谢谢！
