O que costuma-se supor

Calling jest.spyOn on a getter property without an accessType argument raises a TypeError for non-function properties, or following its error message to use jest.replaceProperty successfully mocks the property value.

O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.

Contrato

• jest.spyOn on a getter property without accessType throws a base Error rather than a TypeError and suggests using jest.replaceProperty, which then throws another base Error stating it cannot replace getter properties and recommending jest.spyOn(object, property, 'get').
• jest.spyOn(object, getterName) throws an Error instance where err instanceof TypeError is false
• jest.replaceProperty(object, getterName, value) throws an Error instance recommending accessType 'get'
• jest.spyOn(object, getterName, 'get') successfully creates a getter mock that permits mockReturnValue
