Problem description

Window.open is used in the code to open a new window, and an error is reported in jest unit test

 window.open(url, name, config)

jest not implemented window.open()

Solution:

Directly define the window. Open method in the test file, which should be suitable for all window methods.

window.open = jest.fn()

Note that the mockclear() method is always called in the test file, because window.Open is a global object and will always exist during the test.

it('test', () => {
  window.open.mockClear()
  wrapper.vm.handleOpen()
})
