Ce que l'on suppose souvent
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.
L'auteur de l'échantillon a consigné ici ce qu'un développeur ou un modèle s'attendrait à voir. Le contrat ci-dessous est ce qui s'est réellement exécuté.
Contrat
- 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
