title: Could not find declaration file for enzyme-adapter-react-16?
body: <p>I've been using Enzyme to test components in my React application for some time. After updating my packages for the first time in a few weeks I've started getting an error from my tests.</p>
  
  <pre><code> FAIL  src/__tests__/title.test.ts
    ● Testing title component › renders
  Enzyme Internal Error: Enzyme expects an adapter to be configured, but found none. [...] 
  To find out more about this, see http://airbnb.io/enzyme/docs/installation/index.html
  </code></pre>
  
  <p>I proceed to install <code>'enzyme-adapter-react-16'</code> as described in the link and add the following lines to my test file:</p>
  
  <pre><code>import * as enzyme from 'enzyme';
  import Adapter from 'enzyme-adapter-react-16';
  enzyme.configure({ adapter: new Adapter() });
  </code></pre>
  
  <p>However, as my application is written in TypeScript, I now run into two new problems.</p>

  <a href="https://i.stack.imgur.com/NC0JQ.png" rel="noreferrer"><img src="https://i.stack.imgur.com/NC0JQ.png" alt="error2"></a></p>
  
  <p>To clarify the images the first error, TS7016, is that there aren't any types for <code>enzyme-adapter-react-16</code>, and the second error, TS2339, says that <code>enzyme</code> does not have the property <code>configure</code>.</p>
  
  <p>I'm relatively new to TypeScript so I need some help. I've tried to install types for <code>enzyme-adapter-react-16</code> but those do not appear to exist. </p>
  
  <p><strong>Should I attempt to add them myself, or is there some way I can avoid this problem all together?</strong></p>
  
  <p>Also curious what made this error appear. I didn't need an Adapter before, why now?</p>
