Spy or stub methods before mount

I’ve got some methods that are called on created, mounted events. I can’t seem to be able to spy on them properly (or make stubs).

What I tried so far is, is spying on methods of pre mounted element and then checking if the spy was called. This doesn’t work even when the actual method was called (tested by adding simple consolel.og)

Example:

it('calls myMethod when mounted', () => {
  const spy = sinon.spy(myComponent.methods, 'myMethod')
  const wrapper = mount(myComponent, { propsData, store })
  expect(spy.called).to.be.true // AssertionError: expected false to be true
})

Using Karma, Mocha and Sinon. I hope this is enough info and appropriate place to ask this.

This test works for me -

it('calls changeMessage on mount', () => {
  const spy = sinon.spy(Foo.methods, 'focusOnComposer')
  mount(Foo)
  expect(spy.called).to.be.true
});

There must be something else going on here.

Can you link me to the full repo?
