+to wrap your React components with a div wrapper.
+
+```jsx
+<div id='parent'>
+  <div id='child' />
+<div>
+```
+
+```js
+// Enzyme 2
+wrapper.find('#parent').length //=> 1
+wrapper.is('#parent') //=> false
+
+// Enzyme 3
+wrapper.find('#parent').length //=> 0
+wrapper.is('#parent') //=> true
+```
