I looked through the patterns and I wonder what makes them 'idiomatic'? I've found it useful to use wrapper libraries like Enzyme [0] and Teaspoon [1] when testing React components and interactions. [0] https://github.com/airbnb/enzyme [1] https://github.com/jquense/teaspoon

I'm a fan of HOCs as well. My only problem with them is that I'm also a fan of shallow testing, and HOCs don't play nicely with shallow testing. I'm waiting on something like this (https://github.com/airbnb/enzyme/issues/250) to get implemented

See also Enzyme, a testing library specifically for React, that allows you to easy assert on both deep and shallow renders of the React DOM. https://github.com/airbnb/enzyme#basic-usage

I first encountered LGTM on some of Airbnb's open source repos, here's an example of it at work on a closed [1] and open [2] Enzyme PR: 1: https://github.com/airbnb/enzyme/pull/449 2: https://github.com/airbnb/enzyme/pull/459 I love that this enforces a social practice a lot of teams use already, and I'm pushing to add it to my own team's workflow (both internal and for open source contributions). Edit: another tool in the same vein people might be interested in is Facebook's mention-bot [3], which analyzes PR diffs and @-mentions people it thinks would be good reviewers based on git blame of lines touched. 3: https://github.com/facebook/mention-bot

In LGTM is a simple pull request approval system for GitHub
