- Note that there's currently a bug with the 4.1.x versions where a failure in an expect will leak a variable to the global scope, causing mocha to report that leak instead of the actual failure.

Introduction
Update chai to a more recent version. This required a small change in one of the test helpers.
Motivation
David was showing it as outdated with a red semaphore and everything which made me sad 😢
Proposed solution
Unfortunately we can't update to the more recent version (4.1.2) due to a bug in that version that causes the wrong error to be reported when an
expect()fails.The
countModels()test helper method had to be changed to do type coercion fromstringtonumber. This wasn't a problem before because chai did this coercion itself in thewithin,above,least,below,most,increaseanddecreasemethods, but that changed with version 4.0.0.Current PR Issues
Not the most recent version, but close enough.
