v3.0 - Enzyme 3 and React 16 compatibility

There it is, a new major version!

Features

• Works with Enzyme v3 and React 16
• Support top level array components (new in React 16)
• Remove mountToShallowJson and mountToDeepJson and use options instead
• Simplified Readme
• Refactor documentation
• TypeScript bindings

Breaking changes

• Components returning null or any falsy value are now rendered as an empty string in snapshots instead of null

• Shallow wrapper are now outputting undefined props:

  <BasicWithUndefined>
-   <button>
+   <button
+     disabled={undefined}
+   >
      Hello
    </button>
  </BasicWithUndefined>

• This use case won't be supported anymore, it seems incorrect anyway to pass this as a prop and I can see no usage of this in the react-bootstrap documentation anyway

• This use case won't be supported either as it doesn't seem to be supported by Enzyme either, you will just have to use their simulate helper to do that

• mountToShallowJson and mountToDeepJson are replaced by a mode option in mountToJson:

mountToShallowJson(wrapper);
// ==>
mountToJson(wrapper, {mode: 'shallow'});

mountToDeepJson(wrapper);
// ==>
mountToJson(wrapper, {mode: 'deep'});
