Enzyme: "Cannot read property '_reactInternalFiber' of null" with storybook-addon-specifications

[zhanglid]

Current behavior

mount does not work. Cannot read property '_reactInternalFiber' of null

I am using storybook-addon-specifications for storybook.

I found the line 40 executed after line 52, which causes the inst null.

Expected behavior

No error.

Are you confident about which version of React storybook is bundling up?

@arwalokhandwala if you could provide any info for your setup that differs from the OP, that would be helpful.
