测试逻辑在这里

import { render, screen } from "@testing-library/react"
import userEvent from "@testing-library/user-event"
import NavBar from "@/components/NavBar";

describe("<NavBar>", () => {
    it ("the login pop out displayed after click the login/sign up button", async () => {
        render(<NavBar />);

        const loginButton = screen.getByRole("link", {
            name: "LOGIN/SIGN UP"
        });
        const loginCard = screen.getByTestId("loginCard");

        await userEvent.click(loginButton);
        expect(loginButton).toBeCalled();
        expect(loginCard).toBeVisible();
    })
});

组件在这里：导航栏：

"use client"

import React, { Dispatch, SetStateAction } from "react";
import { useRouter } from "next/navigation";

interface NavBarProps {
  setVisibleLogin?: Dispatch<SetStateAction<boolean>>; …
