I am attempting to mock an object that is referenced by my method with jest. I would like to change the value of the referenced object to something else for testing.

example:

External function and object

// ./external.js

export const functionToTest() {
   const object = objectIWantToMock;
   return 'result using object';
}

export const objectIWantToMock = {
    stuff: {}
}

test file:

// ./external.test.js

explain('when object is different', () => {
   it('should do something different', () => {
       // how to mock object when it is called by functionToTest?
   })
})
