如何覆盖Promise.all(...)使用单元测试的语句

// 假设你的代码中有一个名为myFunction的函数，其中使用了Promise.all(...)
describe('myFunction', () => {
  it('should resolve when all promises are resolved', async () => {
    const promises = [
      Promise.resolve('Promise 1'),
      Promise.resolve('Promise 2'),
      Promise.resolve('Promise 3')
    ];

    const result = await myFunction(promises);

    expect(result).toEqual(['Promise 1', 'Promise 2', 'Promise 3']);
  });

  it('should reject if any promise is rejected', async () => {
    const promises = [
      Promise.resolve('Promise 1'),
      Promise.reject(new Error('Promise 2 failed')),
      Promise.resolve('Promise 3')
    ];

    await expect(myFunction(promises)).rejects.toThrow('Promise 2 failed');
  });
});
