我几天前开始使用Capybara，之前从未使用过Selenium。
我想看看我的测试如何在beowser中执行并使用它为gem #ifndef X265_LOWRES_H

我在Capybara有下一个测试：
selenium-webdriver将RSpec.feature 'Authentication', :type => :feature do
def register_with_form
visit '/'
click_on 'Account'
click_on 'Register'
fill_in 'Email', :with => 'test@example.com'
fill_in 'Name', :with => 'John'
fill_in 'Last name', :with => 'Smith'
fill_in 'Password', :with => '1234567890'
fill_in 'Password confirmation', :with => '1234567890'
find('.testing-sign-up-class')
click_button 'Sign up'
expect(page).to have_css '.hd-title', 'Get Started'
end
scenario 'User registers' do
register_with_form
expect(page).to have_css '.hd-title', 'Get Started'
expect(page).to have_css '.alert-success', 'Welcome! You have signed up successfully.'
expect(page).to have_css '.panel-title', 'What would you like to use GridHub for?'
end
scenario 'User sign out', :js => true do
register_with_form
click_on 'Account'
click_on 'Logout'
expect(page).to have_css '.alert-success', 'Signed out successfully.'
end
end
添加到任何:js => true破解测试中。
控制台显示：
scenario我添加了gem database_cleaner，我的 1) Authentication When not registered User sign out
Failure/Error: click_button 'Sign up'
Selenium::WebDriver::Error::UnknownError:
Element is not clickable at point (606, 23.73333740234375). Other element would receive the click: <input autocomplete="off" name="term" id="term" class="form-control nav-search-field main-ac autocomplete ui-autocomplete-input" placeholder="search items" data-url="/search" type="text">
有下一个代码：
spec_helper.rb我的 config.before(:each, type: :feature) do
driver_shares_db_connection_with_specs = Capybara.current_driver == :rack_test
if !driver_shares_db_connection_with_specs
DatabaseCleaner.strategy = :truncation
end
end
config.before(:each) do
DatabaseCleaner.start
end
config.append_after(:each) do
DatabaseCleaner.clean
end
文件有下一行：
bin/rspec感谢。
更新
我认为浏览器中可能存在其他问题。在某些情况下，当测试打开浏览器时（因为我遇到了firefox和chrome），而某些元素可能会在“浏览器窗口下方”，在这种情况下测试失败，导致无法找到必要的按钮。 如果我有时间向下滚动浏览器窗口，一些测试可能会成功。
答案 0 :(得分：0)
使用任何支持JS的驱动程序click_button时，只需单击按钮然后继续。它不会等待页面上的任何内容发生变化，因为它无法知道预期会发生什么变化。我的猜测是，当您的测试调用register_with_form并返回时，它会立即点击“帐户”＃39;链接与表单位于同一页面上。这将最终取消注册提交并转到没有注销链接的页面。要解决此问题，您需要将register_with_form的最后一行设为expect(page).to have_content('Welcome!')，以便在注册完成之前不会返回。
此外，使用https://github.com/DatabaseCleaner/database_cleaner#rspec-with-capybara-example中建议的database_cleaner设置（append_after非常重要）而不是您拥有的设置，或者您最终难以诊断数据库在请求之前开始清理的问题已经完成等等。
