当我测试 <Link />
行为时,期望它重定向到某个路由,会出现 TypeError (Cannot read property 'push' of null
)。
这是我目前正在测试的组件:
import React from "react"
import Link from "next/link"
const Sandbox = () => {
return (
<div>
<Link href="/about">
<a data-testid="mytest">Click Me</a>
</Link>
</div>
)
}
export default Sandbox
这是我正在运行的测试:
import React from "react"
import { render, fireEvent } from "@testing-library/react"
import { useRouter } from "next/router"
import Sandbox from ".."
jest.mock("next/router", () => ({
useRouter: jest.fn(),
}))
describe("Sandbox", () => {
it.only("should navigate accordingly", () => {
const push = jest.fn()
useRouter.mockImplementationOnce(() => ({
asPath: "/",
push,
}))
const { getByTestId } = render(<Sandbox />)
const mytest = getByTestId("mytest")
fireEvent.click(mytest)
expect(push).toHaveBeenCalledWith("/about")
})
})
我相信我已经嘲笑了我需要的一切,所以我真的不明白为什么路由器实际上不能“推送”。 我在这里错过了什么?
