Shallow + intl

SimpleSearch.test.js

import { shallow } from 'enzyme';
import { SimpleSearch } from '../../src/containers/SimpleSearch';
import { IntlProvider } from 'react-intl';

const intlProvider = new IntlProvider({locale: 'en'}, {});

describe('<SimpleSearch/>', () => {
    let wrapper, {intl} = intlProvider.getChildContext();

    beforeEach(() => {
        wrapper = shallow(<SimpleSearch/>, { context: { intl } });
    });

    it('renders', () => {
        console.log(wrapper.html());
    });
});
