Jest JS branch and statement not covered and

I am creating some tests for my components.

But when I run coverage, I have this error:

import React from 'react';  IEE (statement not covered)
import classNames from "classnames"; EIII (branch not covered)

someone knows what happens?

that's my test and my component:

pagination-test.js

jest.unmock('../../../components/content/elements/pagination');

import React from 'react';
import ReactDOM from 'react-dom';
import TestUtils from 'react-addons-test-utils';
import Pagination from '../../../components/content/elements/pagination';

describe('Pagination', () => {
    let setCurrentPage = jest.genMockFunction();
    it('should render', () => {
        let pagination = TestUtils.renderIntoDocument(
            <Pagination setCurrentPage={setCurrentPage} page={1} totalPages={10} />
        );
        expect(pagination).toBeDefined();
    });
    it ('should have pagination element', () => {
        let pagination = TestUtils.renderIntoDocument(
            <Pagination setCurrentPage={setCurrentPage} page={1} total Pages={10} />
        );
        let renderedPagination = TestUtils.scryRenderedDOMComponentsWithTag(pagination, "li");
        expect(renderedPagination.length).toEqual(12);
    });
    it ('should havent pagination element', () => {
        let pagination = TestUtils.renderIntoDocument(
            <Pagination setCurrentPage={setCurrentPage} page={0} totalPages={0} />
        );
        let renderedPagination = TestUtils.scryRenderedDOMComponentsWithTag(pagination, "ul");
        expect(renderedPagination.length).toEqual(0);
    });
});

pagination.js

import React from 'react';
import classNames from "classnames";

let PropTypes = React.PropTypes;

class Pagination extends React.Component {
    constructor(props) {
        super(props);
    }

    render() {
        if (this.props.totalPages === 0) {
            return React.DOM.div({'key': 'div-no-pagination'}, '');
        }
        let totalPages = [];
        for (let x = 1; x <= this.props.totalPages; x++) {
            totalPages.push(x);
        }
        let itinerator = 0;
        let pages = totalPages.map(function(page) {
        itinerator++;
        let attr = {
            href: '',
            onClick: this.props.setCurrentPage.bind(this, page),
            key: 'link_' + itinerator
        }

        let link = React.DOM.a(attr, page);
        let active = false;
        if (page == this.props.page) {
            let active = true;
            link = React.DOM.span({}, page);
        }
        return React.DOM.li({key: 'li_' + itinerator, className: classNames({'active': active})}, link);
    }.bind(this));

    let attrBack = {
        href: '',
        className: 'btn',
        onClick: this.props.setCurrentPage.bind(this, (parseInt(this.props.page) - 1))
    };
    let attrNext = {
        href: '',
        className: 'btn',
        onClick: this.props.setCurrentPage.bind(this, (parseInt(this.props.page) + 1))
    };
    let pagination = React.DOM.div({}, 
        React.DOM.ul({}, 
            React.DOM.li({}, React.DOM.a(attrBack, React.DOM.i({className: classNames({'fa fa-chevron-left': (this.props.page != 1)})}))),
            pages,
            React.DOM.li({}, React.DOM.a(attrNext, React.DOM.i({className: classNames({'fa fa-chevron-right': (this.props.page != this.props.totalPages)})})))
            )
        );
        return (pagination);
    }
}

Pagination.propTypes = {
  setCurrentPage: PropTypes.func.isRequired,
  page: PropTypes.number.isRequired,
  totalPages: PropTypes.number.isRequired,
}

export default Pagination;

After exec jest --coverage, I have this
