toMatchElement not respecting Arrays

[vitreuz]

It seems that as per the documentation toMatchElement is meant to match on props, however when the prop is an array it ignores the content.

Ex:

it("renders 5 0's", () => {
  const wrapper = shallow(<MyComponent />)

  expect(wrapper).toMatchElement(<MyRow row={[0, 0, 0, 0]} />)
);

This would successfully match on:

<MyRow row={["some", "random", "values"]} />

So, the logic for matching element is actually really simple. It just runs enzyme's debug() method and compares the strings.

I did a test and enzyme masks objects and arrays. This is unexpected, I thought it used to work..

Either way, I've got a ticket going with Enzyme to see where the fix lies: enzymejs/enzyme#1476

I put up a PR in enzyme for this. So hopefully this will get fixed soon
