Storyshots: make warnings fail unit-tests

[andoks]

I have a recurring issue where broken tests errors out without generating appropriate snapshots due to reasons unrelated to the snapshot itself, but issues with how I have written the story. The story typically works in storybook, and is shown in the catalogue as expected, but storyshots fails to generate snaphots of the component (and sometimes even subsequent components), but the unit-test still passes.

Is there a way for me to configure either storyshot, storybook or jest itself to fail the unit-test in such cases?
