TypeError: Cannot read property 'pathname' of undefined in react/redux testing

I'm testing some react components, a basic tests suite just to know if a component is rendering and their childs.

I'm using redux-mock-store to make the store and {mount} enzyme to mount the container in a provider, but even mocking the correct store this error is always fired:

TypeError: Cannot read property 'pathname' of undefined

Here is my very deadly basic test:

import React from 'react';
import { mount } from 'enzyme';
import configureStore from 'redux-mock-store';
import { Provider } from 'react-redux';
import App from '../containers/App.container';

describe('App', () => {
  let wrapper;
  const mockStore = configureStore([]);
  const store = mockStore({
    router: {
      location: { pathname: '/home', query: {}, search: '' },
      params: {}
    }
  });
  console.log(store.getState());
  beforeEach(() => {
    wrapper = mount(
      <Provider store={store}>
        <App />
      </Provider>
    );
  });

  it('Should render app and container elements', () => {
    expect(wrapper.find('.app').exists()).toBeTruthy();
    expect(wrapper.find('.container').exists()).toBeTruthy();
  });

  it('Should render the navbar', () => {
    expect(wrapper.find('nav').exists()).toBeTruthy();
  });
});

And the (even more) simple component / container:

import React, { Component } from 'react';
import NavBar from '../components/Navbar';

class App extends Component {

  render() {
    const { location, logout} = this.props;
    console.log(location);
    return (
      <section className='app'>
        <NavBar location={location.pathname} onLogoutClick={logout}/>
        <div className='container'>
          {this.props.children}
        </div>
      </section>
    );
  }
}

export default App;

Container:

import { connect } from 'react-redux';
import { signOut } from '../actions/auth.actions'
import App from '../components/App';

const mapStateToProps = (state, ownProps) => {
  return {
    location: ownProps.location
  }
}

const mapDispatchToProps = (dispatch, ownProps) => {
  return {
    logout: () => {
      dispatch(signOut())
    }
  }
};

export default connect(mapStateToProps, mapDispatchToProps)(App);

I can't figure out the problem of the test, the mockStore is in the correct format:

Any idea?

Update:

Thinking about it, I have no reducer / prop in the rootReducer for the location, but, i just want to pass down through the children components the location object properties that react-redux-router make available in the ownProps argument.

Weird fact: logging the location property in the app returns me the correct object.

In the tests, is always undefined... (as the error shows).

Here is my rootReducer:

import { combineReducers } from 'redux';
import { reducer as formReducer } from 'redux-form';
import { routerReducer } from 'react-router-redux';

import authReducer from './auth.reducer';
import analysisReportsReducer from './AnalysisReports.reducer';
import titleAnalysisReducer from './TitleAnalysis.reducer';
import postsReportsReducer from './PostsReports.reducer';

const rootReducer = combineReducers({
  form:             formReducer,
  routing:          routerReducer,
  auth:             authReducer,
  analysis:         titleAnalysisReducer,
  analysis_reports: analysisReportsReducer,
  posts:            postsReportsReducer
});

export default rootReducer;
