One non-blocking question/suggestion
What is the current behavior?
The original issue claimed a Rollup error when writing functional components in tests. However I wasn't able to reproduce this behavior.
Instead, trying to render a functional component in unit tests would fail with the error:
STENCIL-751
fixes #4063
What is the new behavior?
Changing the testing module to accept functional components by essentially just skipping the parts where it tries to access the component meta data.
STENCIL-751
Documentation
Does this introduce a breaking change?
Testing
Added some unit tests where I render functional and class components and mix them together. Probably not exhaustive but it validates that both types of components can be rendered.
