Support for React Router

Current behavior:

I’m prototyping using Cypress to test our app. But I ran into difficulty right away with the the location URL not being updated in the test runner. Our app uses React Router V4 to handle navigations in our single-page-app. This means we aren’t actually doing requests to the server for each URL change. Rather, we are updating the URL to give the appearance that the user is on a new page, but behind the scenes we are only making requests for data to the server and not an actual request for the page in the browser’s URL.

So when I run the a test like this:

    const nextButtonSelector = 'button[type=submit]';

    cy.visit('https://accounts.outreach.io/users/sign_in')
    cy.get('#user_email').type('username');
    cy.get(nextButtonSelector).click();
    cy.get('input[type=password]').type('passord!');
    cy.get(nextButtonSelector).click();
    cy.location('pathname').should('include', '360');

It logs-in just fine, but it fails to find the “360” page in the URL. This is not actually a URL that we issue an HTTP request for. Rather, it’s a react-router “route” that should show in the browser’s URL and then we completely client-side render the page in React.

Desired behavior:

The URL in the Cypress test runner should update just like the URL of the normal browser window when it is not being controlled by Cypress.

Steps to reproduce:

I’d like to know if anyone else has had Cypress running via React-Router. If not, I’m happy to help set-up a small app using React Router so that there’s an easy repro environment. I just would like to know first if this is a new feature or just a bug fix first before going through that effort.

I don’t see any error thrown. I just don’t see the URL being updated. When the code executes cy.location('pathname').should('include', '360'); it returns false because the URL is not updated. I’ll see if I can get something setup in a few days to have a more localized repro.
