Vue Component cannot be passed to mount

[No9]

Version

1.0.0-beta.16

Reproduction link

https://github.com/No9/vue-test-utils-issue

Steps to reproduce

See repo

> git clone https://github.com/No9/vue-test-utils-issue.git
> cd vue-test-utils-issue
> npm install
> npm test

What is expected?

Passing a Vue Component to vue-test-utils.mount should work as per
#329 (comment)

What is actually happening?

An error is thrown that wrapper.html() is undefined

---

I may have misunderstood the use of the wrapper and the library here and unpacking the vue as per the first passing test is expected behavior.

Thanks for the detailed bug report. It was easy to find the problem using your minimal reproduction 😀

The issue was that we weren't compiling extended components correctly. I've fixed this and it will be in the next release. Worth noting that this isn't fixed in Vue < 2.3 due to a bug with mergeOptions.

Thanks @eddyerburgh - I am on vue@latest so that doesn't impact -
Glad it was a useful report and thanks again for turning it around.
