HTTP basic auth for Capybara

Question

I\'m writing some RSpec tests for my Rails 3 application and trying to switch from Webrat to Capybara. So far so good but the application uses HTTP basic auth to authorize m

Answer 1

Man, none of these solutions worked for me.

Pistos' solution came close and worked for feature specs with js: true but failed when headless.

This below solution works for me for both headless and js: true specs.

spec/support/when_authenticated.rb

RSpec.shared_context 'When authenticated' do
  background do
    authenticate
  end

  def authenticate
    if page.driver.browser.respond_to?(:authorize)
      # When headless
      page.driver.browser.authorize(username, password)
    else
      # When javascript test
      visit "http://#{username}:#{password}@#{host}:#{port}/"     
     end
  end

  def username
    # Your value here. Replace with string or config location
    Rails.application.secrets.http_auth_username
  end

  def password
    # Your value here. Replace with string or config location
    Rails.application.secrets.http_auth_password
  end

  def host
    Capybara.current_session.server.host
  end

  def port
    Capybara.current_session.server.port
  end
end

Then, in your spec:

feature 'User does something' do
  include_context 'When authenticated'

  # test examples
end

Answer 2

None of the page.driver.* solutions worked for me. I'm using Poltergeist, not Selenium, so that might have something to do with it. Here's what did work:

RSpec.shared_context "When authenticated" do
  before do
    username = 'yourusername'
    password = 'yourpassword'
    visit "http://#{username}:#{password}@#{Capybara.current_session.server.host}:#{Capybara.current_session.server.port}/"
  end
end

Then, in your spec:

feature "Your feature", js: true do
  include_context "When authenticated"

  # Your test code here...
end

Answer 3

The default Capybara driver, rack-test, has a basic_authorize method (with alias authorize) for Basic HTTP Auth, and digest_authorize for Digest HTTP Auth, here you can find them: https://github.com/brynary/rack-test/blob/master/lib/rack/test.rb

So you can do:

page.driver.browser.authorize 'login', 'password'

Or you can write a simple helper for Basic HTTP Auth:

def basic_auth(user, password)
  encoded_login = ["#{user}:#{password}"].pack("m*")
  page.driver.header 'Authorization', "Basic #{encoded_login}"
end

Answer 4

This has changed in recent versions of cucumber-rails (I am using 1.0.2).

cucumber-rails uses the Rack/Test driver by default, so if you have not changed that, the following instructions will work.

Create features/step_definitions/authorize.rb:

Given /^I am logged in as "([^\"]*)" with "([^\"]*)"$/ do |username, password|
  authorize username, password
end

Now you can use this in your features:

Given I am logged in as "admin" with "password"

Answer 5

I had to do this horrible hack to get it work worth headless and with javascript

Given /^I am logged in$/ do
 if page.driver.respond_to?(:basic_authorize)
   page.driver.basic_authorize('admin', 'password')
 else
   # FIXME for this to work you need to add pref("network.http.phishy-userpass-length", 255); to /Applications/Firefox.app/Contents/MacOS/defaults/pref/firefox.js
   page.driver.visit('/')
   page.driver.visit("http://admin:password@#{page.driver.current_url.gsub(/^http\:\/\//, '')}")
 end
end

Answer 6

I got it to work using page.driver.basic_authorize(name, password) instead

Update:

At the moment, after a Capybara upgrade, I'm using this pile of workarounds:

if page.driver.respond_to?(:basic_auth)
  page.driver.basic_auth(name, password)
elsif page.driver.respond_to?(:basic_authorize)
  page.driver.basic_authorize(name, password)
elsif page.driver.respond_to?(:browser) && page.driver.browser.respond_to?(:basic_authorize)
  page.driver.browser.basic_authorize(name, password)
else
  raise "I don't know how to log in!"
end
