Component template requires a root element, rather than just text

[wagerfield]

Version

1.0.0-beta.18

Reproduction link

https://codesandbox.io/s/o1r1qw3qq

Steps to reproduce

1. Take a look at src/TestComponent.spec.js
2. Look at the Console tab and observe the error:

[Vue warn]: Error compiling template:

Hello

- Component template requires a root element, rather than just text.

3. Look at Tests tab and observe that both the "mount with default slot" and "shallowMount with default slot" are failing when using the default slot to pass some text to the TestComponent

What is expected?

All tests should pass. The two tests "with default slot" should match the expected html <button>Hello</button>

What is actually happening?

The 2 failing tests are rendering the html <button><div></div></button>

---

If you roll back to @vue/[email protected] the tests pass, so this is clearly a bug with the latest beta release.

to me, this is similar to #693 . CompileToFunctions seems not handling text only. Since a string is not generating a valid AST and throwing errors, then maybe it makes sense to reconsider the approach and rely on the compile function only (where it makes sense).

I think putting text to slots mounting option is not supported after 1.0.0-beta.17.

There was a breaking change where we no longer resolve values in slots (like this.someVal).

This is a bug that we should fix
