My very basic feature specs are passing just fine locally but failing on CircleCI and Codeship. The tests that are failing:
require 'spec_helper'
describe 'Authentication' do
describe "sign in" do
it "is the landing page for non-authenticated users" do
user = create(:user)
visit root_path
expect( page ).to have_content 'LOG IN' # On sign-in page
fill_in 'Email', with: user.email
fill_in "Password", with: user.password
click_button 'Sign in'
expect( current_path ).to eq user_path(user)
end
end
describe 'registration' do
it "allows new users to register" do
visit root_path
click_link 'Sign up'
fill_in 'Email', with: '[email protected]'
fill_in 'Password', with: 'password'
fill_in 'Password confirmation', with: 'password'
fill_in 'First name', with: 'John'
fill_in 'Last name', with: 'Doe'
click_button "Sign up"
expect( current_path ).to include '/users/'
expect( page ).to have_content "Welcome! You have signed up successfully."
end
end
end
The tests both fail on the first lines where they set expectations of the pages (expect( page ).to have_content "LOG IN" and click_link "Sign up", respectively), with errors suggesting the page HTML is completely blank:
expected to find text "LOG IN" in ""
I saved screenshots on CircleCI, and they indeed show a completely blank page.
Here's where it gets interesting. I tried debugging the problem by running/watching the specs on Circle using a VNC. When I a) set driver: :selenium for the tests, b) add a sleep 1 or two to the tests before testing the page expectations, and c) manually run the test after SSHing into their servers with the VNC, I can see the tests run in Selenium (they open a browser in the VNC) and they pass perfectly.
Outside of the VNC, however, the tests fail consistently in both CI servers. With or without tons of sleeps and driver: :selenium. Any ideas what could be causing this discrepancy between the regular CircleCI/Codeship servers and their VCN/my local test environment? I got in touch with the folks at CircleCI, but they're stumped for the moment.
If relevant, I'm running Ruby 2.2.0, Rails 4.2, Capybara 2.4.4, Capybara-Webkit 1.4.1, and Selenium-Webdriver 2.44.0
