import semver from 'semver';

expect.addSnapshotSerializer(createSerializer(emotion));
expect.extend(createMatchers(emotion));

// Configure Enzyme for appropriate React version
let Adapter;

} else if (semver.satisfies(React.version, '^16.0.0')) {
  Adapter = require('enzyme-react-adapter-future');
}
Enzyme.configure({ adapter: new Adapter() });
