如何修复错误：useHref() 只能在 a 的上下文中使用<router>零件</router>

Question

How do I resolve this problem. I am just trying to create a test the ensures that that component renders, but for some reason keep getting this problem even though the component is already inside <Router> .

I have read other similar questions on here, and the answers all say to put the component inside the <Router/> , But that doesn't seem to be the issue for me. Please tell me what it is I'm missing?

** My app.tsx**

import './App.scss';
import { AuthContexProvider } from './Utils/Contexs/AuthContext';
import { Routes, Route } from 'react-router-dom';

SignUpView

import { Typography } from '@mui/material';
import { Link } from 'react-router-dom';
import { SignUpForm } from '../Components/Forms/SignUpForm';

//SASS
// import '../Styles/Scss/SignUpView.scss';
import { StyledFormsWrapper } from '../Styles/StyledComponents/StyledFormsWrapper';

export const SignUpView = () => {
  return (
    <StyledFormsWrapper data-testid='todo-1' className='signUpWrapper'>
      <Typography className='actionTitle' variant='h5' gutterBottom component='div' sx={{ fontWeight: 600 }}>
        Create account
      </Typography>
      <Typography variant='subtitle1' gutterBottom component='div'>
        Already have an account? <Link to={'/signin'}>Sign in</Link>
      </Typography>
      <SignUpForm />
    </StyledFormsWrapper>
  );
};

SignUpView.test.js

import React from 'react';
import { render, fireEvent, waitFor, screen } from '@testing-library/react';
import { SignUpView } from '../../Views/SignUpView';

describe('my function or component', () => {
  test('Should render sigUp view component', () => {
    render(<SignUpView />);
  });
});

Answer 1

The SignUpView is missing a routing context in your test. Import a memory router and wrap the component under test so it has a provided routing context.

import React from 'react';
import { render, fireEvent, waitFor, screen } from '@testing-library/react';
import { MemoryRouter as Router } from 'react-router-dom';
import { SignUpView } from '../../Views/SignUpView';

describe('my function or component', () => {
  test('Should render sigUp view component', () => {
    render(
      <Router>
        <SignUpView />
      </Router>
    );
  });
});

Answer 2

for tests you can provide a container wrapper

import { MemoryRouter } from 'react-router-dom';

test('Should render sigUp view component', () => {
  render(<SignUpView />, {wrapper: MemoryRouter});
});
