vue-test-utils: v1.1.4 regression

Subject of the issue

After upgrading from v1.1.3 to v1.1.4 some tests have started to fail.

Steps to reproduce

const wrapper = mount(MyComponent, {
  propsData: {
    items: [
      { name: 'woof' },
      { name: 'bork' }
    ]
  }
});

const items = wrapper.findAllComponents({ name: 'MyComponentItem' });
const firstItem = wrapper.at(0);
//                           ^--- [vue-test-utils]: no item exists at 0

// ...

Expected behaviour

Tests should pass as it was before the upgrade.

Actual behaviour

Tests failed.

Possible Solution

Downgrade to v1.1.3.

Great, I will test a bit more and release a new version this weekend.

Right, I missed your message. I see - one bug remaining.

Can you share the failing test (ideally, simplify it as much as possible). Is it just:

import { RouterLinkStub } from '@vue/test-utils'

const Comp = {
  stubs: { RouterLink: RouterLinkStub },
  template: `<router-link to="/foo" />`
}

shallowMount(Comp).getComponent(RouterLinkStub)

We can add it to this code base (probably with the current PR) and get this merged and released. I think it should not be too difficult once we have a reproduction.

Weird it’s only a RouterLinkStub test failing. That’s the only component we export. I wonder if that’s related. Are you using this exported component or a default stub?

Ok I was able to create a failing test in #1832 depending on my posted example! I added some comments because I encountered some problems. Please have a look @BeeMargarida. I still have no clue what causes it.
