我正在使用RSpec 3和Capybara 2.2.0编写一个简单的登录测试,并且在我的生活中无法弄清楚为什么这个测试会一直失败。
我已经设法确定测试实际上没有点击按钮,但它认为是。另一个奇怪的事情是,即使这不是一个javascript表单,运行测试并将capybara设置为js:true,将呈现一个成功的测试。我错过了什么?

*的 Authentication_pages_spec.rb *
require 'spec_helper'

subject { page }
describe "signin page" do
before { visit signin_path }

的 Sessions.rb 的
class SessionsController < ApplicationController

end
def destroy
end
def create
user = User.find_by(username: params[:session][:username].downcase)
if user && user.authenticate(params[:session][:password])
sign_in user
redirect_to root_path
else
flash.now[:danger] = 'Invalid email/password combination'
render 'new'
end
end
end
的结果: 的
Failures:
1) Authentication signin with valid information should not have title "Sign In"
Failure/Error: should_not have_title("Sign In")
expected there not to be title "Sign In" in "Adventure|Byte Games - Sign In"
# ./spec/features/authentication_pages_spec.rb:39:in `block (4 levels) in <top (required)>'
2) Authentication signin with invalid information should have css "div.alert.alert-danger" with text "Invalid"
Failure/Error: should have_selector('div.alert.alert-danger', text: 'Invalid')
Capybara::ExpectationNotMet:
expected to find css "div.alert.alert-danger" with text "Invalid" but there were no matches
# ./spec/features/authentication_pages_spec.rb:23:in `block (4 levels) in <top (required)>'
添加了登录视图(new.html.erb)
<% provide(:title, "Sign In") %>
<h1>Sign in</h1>
<div class = "container">
<%= form_for(:session, url: sessions_path) do |f| %>
<form role = "form">
<div class="col-md-6 col-md-offset-3">
<div class="form-group">
<%= f.label :username %>
<%= f.text_field :username, class: "form-control" %>
</div>
<div class="form-group">
<%= f.label :password %>
<%= f.password_field :password, class: "form-control"%>
</div>
<div class="form-group">
<%= f.submit "Sign in", class: "btn btn-lg btn-primary" %>
</div>
</div>
</form>
<% end %>
</div>
所以事实证明我在表单上进行格式化,以下视图似乎有效:
<% provide(:title, "Sign In") %>
<h1>Sign in</h1>
<div class = "container">
<div class="col-md-6 col-md-offset-3">
<%= form_for(:session, url: sessions_path) do |f| %>
<%= f.label :username %>
<%= f.text_field :username, class: "form-control" %>
<%= f.label :password %>
<%= f.password_field :password, class: "form-control"%>
<%= f.submit "Sign in", class: "btn btn-lg btn-primary" %>
<% end %>
</div>
</div>
答案 0 :(得分:2)
我个人不会使用click_button方法。它可能非常不稳定。
我喜欢用这种东西
page.find('the.css.for.the.button').trigger('click')
使用触发器('click')的原因是它使用javascript更可靠。
我希望有所帮助。
