Capybara :: ElementNotFound，但是在那里 [英] Capybara::ElementNotFound, but it is there

问题描述

我遇到以下错误:

Capybara::ElementNotFound: Unable to find field "username"
./spec/controllers/sessions_controller_spec.rb:10:in `block (3 levels) in <top (required)>'

规格:

require 'spec_helper'

describe SessionsController do
  before :each do
    @user = FactoryGirl.create(:user)
  end
  context 'creating a new session' do
    it 'can set the current_user variable to the logged user' do
      visit '/login'
      fill_in 'username', with: 'gabrielhilal' #I have tried `Username` as well
      fill_in 'password', with: 'secret'
      click_button 'Login'
      current_user.should == @user
      current_user.username.should == 'gabrielhilal'
    end
  end
  context 'destroying existing session' do
    xit 'can destroy the current_user' do
    end
  end
end

但是我的表单中有字段username:

But I have the field username in my form:

<form accept-charset="UTF-8" action="/sessions" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" / <input name="authenticity_token" type="hidden" value="x7ORLDIvq1BXr8SOkd/Zla9Pl5R5tBXAtyflCpTGCtY=" /></div>
  <div class="field">
    <label for="username">Username</label>
    <input id="username" name="username" type="text" />
  </div>
  <div class="field">
    <label for="password">Password</label>
    <input id="password" name="password" type="password" />
  </div>
  <div class="actions">
    <input name="commit" type="submit" value="Login" />
  </div>
</form>

我对cucumber做了类似的测试，并且通过了测试，该测试确认了字段username在那里:

I did a similar test with cucumber and it is passing, which confirms that the field username is there: When to switch from cucumber to rspec in the BDD cycle for a login procedure

有什么主意吗?

编辑-我添加了save_and_open_page，这给了我一个空白页. puts "#{page.html.inspect}"还会返回经验.

EDIT - I have added the save_and_open_page, which gives me a blank page. The puts "#{page.html.inspect}" also returns empity.

推荐答案

我知道您已经回答了自己的问题(有点)，但是我仍然有必要让您知道您提供的示例是控制器和请求规范的组合...

I know you've already answered your own question (kind of), but I feel it's still warranted to let you know that the example you've provided is a mixture of a controller and a request spec...

引用 RSpec-Controller Specs 的逐字记录: Note: To encourage more isolated testing, views are not rendered by default in controller specs.

主要区别(RSpec解释它是哪种规格的方式)是一行:describe SessionsController do.

The main difference (in the way RSpec interprets what kind of spec it is) is the line: describe SessionsController do.

使其与RSpec和测试最佳实践"保持一致:

To align it with RSpec and Testing best practices:

1. 将规格移至spec/requests
2. 将描述更改为describe "SessionsController" do
3. 删除render_views

1. Move the spec to spec/requests
2. Change the describe to describe "SessionsController" do
3. Remove render_views

您的规范应该可以正常运行...

your spec should run just fine...

查看 RSpec-请求规格，了解我的意思.我还将查看 betterspecs.org ，了解您可以改进测试的方式.

Check out RSpec - Request Specs for what I mean. I would also check out betterspecs.org for ways you can improve on testing.
