React Context.Consumer mocking

AppWithContext.js

import React, { Component } from 'react';

import FruitContext from './FruitContext';
import FruityComponent from './FruityComponent';

export class App extends Component {
  state = {
    fruit: 'apple',
  }

  render() {
    return (
      <FruitContext.Provider value={this.state.fruit}>
        <FruityComponent />
      </FruitContext.Provider>
    );
  }
}

FruitContext.js

import { createContext } from 'react';

export default createContext('banana');

FruityComponent.js

import React from 'react';

import FruitContext from './FruitContext';
import FruityHeader from './FruityHeader';

export default () => (
  <FruitContext.Consumer>
    {fruit => (
      <FruityHeader>{fruit}</FruityHeader>
     )}
  </FruitContext.Consumer>
);

FruityComponent.spec.js

import React from 'react';
import { mount } from 'enzyme';

import FruityComponent from './FruityComponent';

const mockContext = jest.fn();
jest.mock('./FruitContext', () => ({
  Consumer: ({ children }) => children(mockContext()),
}));

describe('FruityComponent', () => {
  beforeEach(() => {
    mockContext.mockReset();  
  });
  
  ['banana', 'apple', 'kumquat'].map(fruit =>
    test(`should pass ${fruit} context to FruityHeader`, () => {
      mockContext.mockReturnValue(fruit);
    
      const fruityHeader = mount(<FruityComponent />).find('FruityHeader');
                            
      expect(fruityHeader.prop('children')).toEqual(fruit);
    }));
});

How would you test AppWithContext.js?

Downside is you would have to have the jest.mock and mockContext.mockReset in every test that required mock context. Why not globally mock the module (https://jestjs.io/docs/en/manual-mocks)?
