使用jest模拟全局对象的字段，如窗口

npm install --save-dev jest @types/jest

// window.test.ts

// 模拟全局对象window
const mockWindow = {
  location: {
    href: 'https://example.com',
    reload: jest.fn(),
  },
};

// 在测试用例中使用模拟的全局对象
describe('window', () => {
  let originalWindow: typeof window;

  beforeAll(() => {
    originalWindow = window;
    // @ts-ignore
    window = mockWindow;
  });

  afterAll(() => {
    window = originalWindow;
  });

  it('should mock window.location.href', () => {
    expect(window.location.href).toBe('https://example.com');
  });

  it('should mock window.location.reload', () => {
    window.location.reload();
    expect(window.location.reload).toHaveBeenCalled();
  });
});

npx jest window.test.ts
