Thanks @Elon Szopos for your answer but I manage to write something much more simple (following https://github.com/airbnb/enzyme/pull/62):
import NavLink from '../index';
import expect from 'expect';
import { shallow } from 'enzyme';
import React from 'react';
describe('<NavLink />', () => {
it('should add active class', () => {
const context = { router: { isActive: (a, b) => true } };
const renderedComponent = shallow(<NavLink to="/home" />, { context });
expect(renderedComponent.hasClass('active')).toEqual(true);
});
});
I have to change mount
to shallow
in order not to evaluate Link
which gives me an error connected with the react-router TypeError: router.createHref is not a function
.
I would rather have “real” react-router than just an object but I have no idea how to create it.
