Invariant Violation: ReactShallowRenderer render(): Invalid component element.

[jahilldev]

I've got everything setup according to your docs however whenever I attempt to shallow render a very simple class based component I get the following error:

Invariant Violation: ReactShallowRenderer render(): Invalid component element.

For clarity I'm using:

"typescript": "2.8.3"
"preact": "8.2.9"
"mocha": "^5.1.1"
"enzyme": "^3.3.0"
"enzyme-adapter-preact": "^0.2.0"

I've put together a repo illustrating this here: https://github.com/jhdevuk/typescript-preact-enyme

Working on a fix for this, should have a merge request ready soon

I still get this error using jest 23.6.0 , enzyme 3.8.0 , and enzyme-preact-adapter 0.2.0 . One not-great workaround is to import React from 'preact-compat'; instead of from 'preact' in test files.
