Loose match one value in jest.toHaveBeenCalledWith

by

This can be done with asymmetric matchers (introduced in Jest 18)

expect(track).toHaveBeenCalledWith(
  expect.objectContaining({
   "action": "PublicationPage", 
   "category": "PublicationPage", 
   "label": "7",
   "name": "n/a"
  })
)

If you use jest-extended you can do something like

expect(track).toHaveBeenCalledWith(
  expect.objectContaining({
   "action": "PublicationPage", 
   "category": "PublicationPage", 
   "label": "7",
   "name": "n/a",
   "intervalInMilliseconds": expect.toBeWithin(999, 1002)
  })
)
