due to the fact that the internal implementation of enzyme has been almost completely rewritten.

The goal of this rewrite was to address a lot of the major issues that have plagued enzyme since

on React internals, and to make enzyme more "pluggable", paving the way for enzyme to be used
with "React-like" libraries such as Preact and Inferno.

We have done our best to make enzyme v3 as API compatible with v2.x as possible, however there are

a handful of breaking changes that we decided we needed to make, intentionally, in order to
support this new architecture and also improve the usability of the library long-term.

Airbnb has one of the largest enzyme test suites, coming in at around 30,000 enzyme unit tests.
After upgrading enzyme to v3.x in Airbnb's code base, 99.6% of these tests succeeded with no
modifications at all. Most of the tests that broke we found to be easy to fix, and some we found to
actually be depending on what could arguably be considered a bug in v2.x, and the breakage was

enzyme now has an "Adapter" system. This means that you now need to install enzyme along with
another module that provides the Adapter that tells enzyme how to work with your version of React

(or whatever other React-like library you are using).

At the time of writing this, enzyme publishes "officially supported" adapters for React 0.13.x,
0.14.x, 15.x, and 16.x. These adapters are npm packages of the form `enzyme-adapter-react-{{version}}`.

You will want to configure enzyme with the adapter you'd like to use before using enzyme in your
tests. The way to do this is whith `enzyme.configure(...)`. For example, if your project depends
