硒與水豚失敗。在瀏覽器中工作

Question

我有一個簡單的登錄系統，在瀏覽器中工作。我最近把我的黃瓜測試切換到使用硒，因爲我需要ajax調用，現在登錄/認證步驟不再通過。該應用程序仍然正常運行在Firefox和鉻。

這裏的步驟和定義

特徵/ authentication.features

Feature: Require Authentication 
    In order to restrict access to the app 
    A User 
    Must be logged in 

    Scenario: Accessing Tracks 
    Given I am not logged in 
    And I visit the "Tracks" page 
    Then I should see the "Welcome" page 
    And I should see "You need to be logged in to access this page" 

    Scenario: Accessing Tracks when Logged in 
    Given I am logged in  
    And I visit the "Tracks" page 
    Then I should see the "Tracks" page  

特徵/ step_definitions/register_and_login_steps.rb

When(/^I log in as "(.*?)"$/) do |name| 
    create_and_login(name) 
end 

When(/^I log in$/) do   
    create_and_login('tester') 
end 

When(/^I log out$/) do   
    visit(logout_path) 
end 

When(/^I should be logged out$/) do 
    page.should have_title "Welcome" 
    page.should have_text "Please log in" 
end 

When(/^I am(not)? logged in$/) do |negative| 
    if negative 
    visit(logout_path) 
    else 
    create_and_login('anyone') 
    page.should have_title 'Welcome' 
    end 
end 

特徵/ step_definitions/should_see_steps.r b

When(/I should(not)? see the "(.*?)" page$/) do |negative, page_title| 
    if negative 
    page.should_not have_title page_title 
    else 
    page.should have_title page_title 
    end 
end 

When(/^I should(not)? see "(.*?)"$/) do |negative, text| 
    if negative 
    page.should_not have_text text 
    else 
    page.should have_text text 
    end 
end 

When(/^I visit the "(.*?)" page$/) do |page| 
    path = page.downcase + "_path" 
    visit_path(path) 
end 

特徵/支持/助手/ user.rb

def password_for(user) 
    user + '_password_' 
end 

def create_user(name) 
    return if User.exists?(name: name) 
    user = User.create!(name: name, 
    password: password_for(name), 
    password_confirmation: password_for(name)) 
end 

def create_and_login(name) 
    create_user(name) 
    visit(logout_path) 
    visit(login_path) 
    fill_in 'Name', with: name 
    fill_in 'Password', with: password_for(name) 
    click_button 'Login' 
end 

的Gemfile（只試驗組）

group :test do 
    gem 'guard-spork', '~> 1.5.0' 
    gem 'rb-inotify', '~> 0.9.0' 
    gem 'spork', '~> 0.9.2' 

    gem 'guard-rspec','~> 2.5.0' 

    gem 'cucumber-rails' , '~> 1.3.0' 
    gem 'database_cleaner','~> 0.9.1' 
    gem 'guard-cucumber', '~> 1.3.2' 
    gem 'capybara', '~> 2.1.0' 
    gem 'selenium-webdriver', '~>2.31.0' 
end

Answer 1

解決的辦法是不要將selenium設置爲默認的水豚驅動程序，並用@javascript標記需要ajax的測試。
