What I did

Set modules to 'commonjs' when NODE_ENV === 'test'.

How to test

Simply test against the storyshot demos.

not sure if we should do undefined here or commonjs. the default for this is commonjs but I'm worried it might change in future versions and break support.

[satazor]

I can change it. Anyways, if they change the default it will be a major bump.

Want me to set to commonjs?

[danielduan]

yeah let's do commonjs

[satazor]

Updated! Also did the same for vue and react-native

[danielduan]

LGTM on crna-kitchen-sink and cra-kitchen-sink

We don't have storyshots set up for vue-kitchen-sink yet.
