[test] window.open test jest, testing-library, 랑 까먹은거

 

window.open = jest.fn();
describe('link test', () => {
  it('move link', () => {
    const { getByRole } = render(
        <Completed />
    );

    userEvent.click(getByRole('button', { name: /click link/i }));
    expect(window.open).toHaveBeenCalledWith(testUrl);
  });
});​

 

Object.defineProperty(window.'location ~~ 이거랑 spyOn 개념 까먹었다.

jest.spyOn(Object.getPrototypeOf(window.localStorage,'removeItem) 이게 mocking 하는건데 추적하기 용이한 막킹이였나
