如何使用jest模拟类和命名空间枚举？

// myClass.js
class MyClass {
  constructor() {
    this.value = 42;
  }

  getValue() {
    return this.value;
  }

  setValue(newValue) {
    this.value = newValue;
  }
}

module.exports = MyClass;

// myClass.test.js
const MyClass = require('./myClass');

jest.mock('./myClass', () => {
  return jest.fn().mockImplementation(() => {
    return {
      getValue: jest.fn().mockReturnValue(100),
      setValue: jest.fn()
    };
  });
});

test('should use mocked class', () => {
  const myClassInstance = new MyClass();
  expect(myClassInstance.getValue()).toBe(100);

  myClassInstance.setValue(200);
  expect(myClassInstance.setValue).toHaveBeenCalledWith(200);
});

// myEnum.ts
export namespace MyEnum {
  export enum Colors {
    RED = 'red',
    GREEN = 'green',
    BLUE = 'blue'
  }
}

// myEnum.test.ts
import { MyEnum } from './myEnum';

jest.mock('./myEnum', () => {
  return {
    MyEnum: {
      Colors: {
        RED: 'mocked_red',
        GREEN: 'mocked_green',
        BLUE: 'mocked_blue'
      }
    }
  };
});

test('should use mocked enum', () => {
  expect(MyEnum.Colors.RED).toBe('mocked_red');
  expect(MyEnum.Colors.GREEN).toBe('mocked_green');
  expect(MyEnum.Colors.BLUE).toBe('mocked_blue');
});
