重复标题，我的问题是如何使用poltergeist通过capybara使用“Enter Key”测试表单提交。换句话说，我希望当我填写用户名，密码然后在任一输入时按“Enter”我将提交表格。从我所知道的，poltergeist通过“send_keys”实现了这一点。但是我目前的测试：
When(/^I log in with enter key$/) do
visit_login
fill_in "app-email", :with => admin_user.email
fill_in "app-password", :with => admin_user.password
login = find("#app-password")
login.native.send_key :Enter
end
使用以下（原始）代码，该代码使用ng-click。我希望上面的代码在下面的代码中失败，因为下面的代码无法在浏览器中输入并提交表单。这是ng-click代码：
%form{name: "form"}
%input#app-email{name: "email", "ng-model" => "email", type: 'email'}
%input#app-password{name: "password", "ng-model" => "password", type: "password"}
%a.btn.btn-primary.login-btn#app-login{"ng-click" => "login(email, password)"} LOG IN
这是带有ng-submit的代码，这两个都是手动和测试的：
%form{name: "form", "ng-submit" => "login(email, password)"}
%input#app-email{name: "email", "ng-model" => "email", type: 'email'}
%input#app-password{name: "password", "ng-model" => "password", type: "password"}
%input.btn.btn-primary.login-btn#app-login{type: "submit", value: "LOG IN"}
有一个相当冗长的讨论，要让它在这里工作：Is there a way to send key presses to Webkit using Capybara?。但是，我无法修改任何适用于我的解决方案。
