wrapper around the corresponding node passed in as the first argument.


#### Arguments

1. `fn` (`Function ( ReactWrapper node, Number index )`): A callback to be run for every node in the collection.
Should expect a ReactWrapper as the first argument, and will be run with a context of the original
instance.

#### Example

```jsx
const wrapper = mount(
  <div>
    <div className="foo bax" />
    <div className="foo bar" />
    <div className="foo baz" />
  </div>
);

wrapper.find('.foo').forEach(function (node) {
  expect(node.hasClass('foo')).to.equal(true);
});
