Page 62: Integration tests fail

[neeklamy]

I can’t get the integration test introduced in Adding Integration Tests to work without modification.

This is the error message reported:

Failures:

  1) Books list page
     Failure/Error: raise ActionController::RoutingError, "No route matches [#{env[ 'REQUEST_METHOD']}] #{env['PATH_INFO'].inspect}"

     ActionController::RoutingError:
       No route matches [GET] "/ember-cli-live-reload.js"

[…]

     # --- Caused by: ---
     # Capybara::ExpectationNotMet:
     #   expected to find text "Books" in "Loading..."

[…]

Before:

# spec/features/books_spec.rb

require 'rails_helper'

feature 'Books', js: true do
  scenario 'list page' do
    visit '/'
    expect(page).to have_content('Books')
  end
end

And here’s the spec after I modified it:

require 'rails_helper'
Capybara.raise_server_errors = false

feature 'Book', js: true do
  scenario 'list page' do
    visit '/'
    sleep 5.second # !important
    expect(page).to have_content('Book')
  end
end

If I leave out the Capybara.raise_server_errors = false, then the RoutingErrors still appear. If I leave out the sleep 5.second, then the browser window pops open and closes before the page has loaded.

Hmm, I don't like that you have to have a sleep. You shouldn't have to do that. What if you kill the line in index.html that contains ember-cli-live-reload.js?

[neeklamy]

That does it perfectly, thanks Jason. I also got rid of the Capybara override too.

There doesn’t seem to be any implications of doing this, I presume because of the Livereload server?

I don't know. The ember-cli-live-reload.js thing goes away in Angular CLI 1.0.0-beta.11-webpack.8 anyway, so it will become a non-issue soon. (I'm currently working on updating the book for that CLI version, by the way, which uses Angular 2.0.0RC5.)
