setMethods is deprecated and will be removed in future releases

Question

I am using the function setMethods, it is still working, however I received the above message on the console. I am wondering what should be the new approach?.

It is being used to spy on a method and then see if it was called with the mocked parameters, here is the code:

const spyGenerateCalendar = jest.spyOn(wrapper.vm, 'generateCalendar');
const spyAxiosRequest = jest.spyOn(axios, 'get');

// setting methods for spying
wrapper.setMethods({generateCalendar: spyGenerateCalendar});

wrapper.vm.generateCalendar();

// Expecting calls
expect(spyGenerateCalendar).toHaveBeenCalled();
expect(spyAxiosRequest).toBeCalledWith(axiosRequestURL, axiosRequestParams);

Answer 1

It is unneeded. I am already spying on the method "generateCalendar" on the line:

  const spyGenerateCalendar = jest.spyOn(wrapper.vm, 'generateCalendar');

So If the line wrapper.setMethods({generateCalendar: spyGenerateCalendar}); is removed. The result will be the same, so expect(spyGenerateCalendar).toHaveBeenCalled(); will be true
