測試通過因為在成功登入時，Navbar 會有 Hi!, <%= current_user.email %>：

<ul class="nav navbar-nav navbar-right">
  <% if !current_user %>
    <li><%= link_to("Login", new_user_session_path) %></li>
  <% else %>
    <li class="dropdown">
      <a href="#" class="dropdown-toggle" data-toggle="dropdown">
        Hi!, <%= current_user.email %>
        <b class="caret"></b>
      </a>
      <ul class="dropdown-menu">
        <li>
          <%= link_to("Logout", destroy_user_session_path, method: :delete) %>
        </li>
      </ul>
    </li>
  <% end %>
</ul>
