In Sinon I can do the following:

var myObj = {

    prop: 'foo'

};



sinon.stub(myObj, 'prop').get(function getterFn() {

    return 'bar';

});



myObj.prop; // 'bar'

But how can I do the same with Jest?
I can't just overwrite the function with something like jest.fn(), because it won't replace the getter

can't set the value of get

Object.defineProperty(myObj, 'prop', {

  get: jest.fn(() => 'bar'),

  set: jest.fn()

});
