Cannot read property 'replace' of undefined

[danielmollmorgan]

I'm currently getting the following error when using mount() - Uncaught TypeError: Cannot read property 'replace' of undefined with the latest version of chai-enzyme.
If I revert to the previous chai-enzyme@0.4.1 there is no error and all runs ok. I haven't been able to track the cause yet.

Dependency versions:

chai-enzyme@0.4.2
enzyme@2.1.0
chai@3.5.0
mocha@2.4.5

Basic example of test that causes the in browser error:

import 'babel-polyfill';
import ArticleTemplate from '../src';
import React from 'react';
import article from '../stubbed/article';
import chai from 'chai';
import chaiEnzyme from 'chai-enzyme';
import { mount } from 'enzyme';

chai.use(chaiEnzyme()).should();

describe('ArticleTemplate', () => {
  let props = null;
  beforeEach(() => {
    props = {
      id: article.id,
      slug: article.slug,
      content: article.content,
    };
  });

  it('renders a React element', () => {
    React.isValidElement(<ArticleTemplate {...props} />).should.equal(true);
  });

  describe('Rendering', () => {
    let rendered = null;
    let articlePage = null;
    beforeEach(() => {
      rendered = mount(<ArticleTemplate {...props} />);
      articlePage = rendered.find('.article-template');
    });

    it('renders <article />', () => {
      articlePage.should.have.tagName('article');
    });
  });
});

Thanks for reporting Daniel, I will look into this :)

@ayrton apologies, I've figured out, and it just must have been a coincidence with reverting back a version but it's down to ads causing a global leak in the tests. Yeah, ads in the test :(
