A vnode's componentOptions does not have a tag value if you pass a constructor as the first argument of createElement (https://github.com/vuejs/vue/blob/dev/src/core/vdom/create-element.js#L119).

Your reproduction demonstrates the expected behavior.

@eddyerburgh hi, i can get the componentOptions.tag of each slots on created() or mounted(). On the test, componentOptions.tag is undefined. Why they are different? Therefore i can't test the component and coverage happened very bad.

Is it a bug or do i mistake?

Example component: https://github.com/Nativescript-Vue-Web/Nativescript-Vue-Web/blob/master/src/components/ActionBar.vue

I think it should need to be fixed, some people will use the componentOptions.tag to check the component type.

I have the same problem, I need componentOptions.tag to check the component type, but it is undefined

It seems resolved on reproduction link on the first post. @zhixinpeng could you write version of test util?

@zhixinpeng sorry it still seems unsolved, you right. The componentOptions.tag is undefined
