I'm running to issues attempting to set cookies using the Poltergeist gem, and from reading through the closed issues at the Poltergeist gem, it appears this is a user error issue on my part, but I've spent a full day now on attempting to get the cookies set properly, and I can't seem to set things up properly.
Note: This test works fine in selenium, but I'd like to use poltergeist due to run time issues with selenium.
The application I'm working on is using "_location" cookie to determine some overall settings, and I need to have the cookie accessible on my first visit of any page in the application. Otherwise I get a javascript error looking for a value that is not set due to the location not being set.
The README for the Poltergeist gem shows the following usage for cookies
Manipulating cookies
The following methods are used to inspect and manipulate cookies:
page.driver.cookies - a hash of cookies accessible to the current page. The keys are cookie names. The values are Cookie objects, with the following methods: name, value, domain, path, secure?, httponly?, expires.
page.driver.set_cookie(name, value, options = {}) - set a cookie. The options hash can take the following keys: :domain, :path, :secure, :httponly, :expires. :expires should be a Time object.
page.driver.remove_cookie(name) - remove a cookie

With this failure, I thought perhaps I should be setting the cookies before visiting the page, however it appears that when I use the page.driver.set_cookie command before I use "visit" in my Capybara scripts, it doesn't actually set anything. As seen from this modified code block and this result set.

I've also attempted to pass in a phantomjs_options block to the poltergeist driver, with an external cookies file. That actually appeared to get me a bit farther, but I ended up with a null cookie_jar. You can see this attempt below:
--spec/spec_helper.rb
Capybara.register_driver :poltergeist do |app|
Capybara::Poltergeist::Driver.new(app, [phantomjs_options: [--cookies-file="#{::Rails.root}/spec/requests/cookies.txt"]] )
end
Capybara.javascript_driver = :poltergeist
-- cookies.txt
phantom.addCookie({
'name': '_location',
'value': 'US',
'domain': 'localhost',
'expires': (new Date()).getTime() + 3600
});
