Maintaining Session with Capybara and Rails 3

问题:

I have two capybara tests, the first of which signs in a user, and the second which is intended to test functions only available to a logged in user.

However, I am not able to get the second test working as the session is not being maintained across tests (as, apparently, it should be).

require 'integration_test_helper'

class SignupTest < ActionController::IntegrationTest

  test 'sign up' do  
    visit '/'
    click_link 'Sign Up!'
    fill_in 'Email', :with => '[e-mail]'
    click_button 'Sign up'
    assert page.has_content?("Password can't be blank")
    fill_in 'Email', :with => '[e-mail]'
    fill_in 'Password', :with => 'password'
    fill_in 'Password confirmation', :with => 'password'
    click_button 'Sign up'
    assert page.has_content?("You have signed up successfully.")
  end

  test 'create a product' do
    visit '/admin'
    save_and_open_page
  end

end

The page generated by the save_and_open_page call is the global login screen, not the admin homepage as I would expect (the signup logs you in). What am I doing wrong here?

The reason this is happening is that tests are transactional, so you lose your state between tests. To get around this you need to replicate the login functionality in a function, and then call it again:

def login
  visit '/'
  fill_in 'Email', :with => '[e-mail]'
  fill_in 'Password', :with => 'password'
  fill_in 'Password confirmation', :with => 'password'
  click_button 'Sign up'
end

test 'sign up' do
 ...
 login
 assert page.has_content?("You have signed up successfully.")
end

test 'create a product' do
  login
  visit '/admin'
  save_and_open_page
end

Each test is run in a clean environment. If you wish to do common setup and teardown tasks, define setup and teardown methods as described in the Rails guides.
