How to mock randstr for snapshots

[bozdoz]

Wondering how I can use jest snapshots while plotly is using its own randstr function (i.e. there's nothing to mock out)

I don't know of a way, unless you've included plotly.js from source in which case you should be able to directly import plotly.js/src/lib and replace Lib.randstr with whatever you want. Anyway the function is defined here, we'd be happy to accept a PR to make it easily mockable.
