如何在Ruby on Rails测试中声明输入元素为空 [英] How to assert that an input element is empty in Ruby on Rails tests

问题描述

我想在编辑用户时确保密码字段为空。我如何在功能测试中做到这一点？

我已经尝试了这两种变体：

  assert_select输入[name =？] [value =？]，'user [password1]'，''
  

和

  assert_tag：tag => input，：attributes => {：name => user [password1]，：value => } 
  

因为没有 value = 属性存在于生成的html中。我看不到有什么方法可以测试生成的html中是否存在 不存在？解决方案

p>试试这个：

  assert_select'input：not（[value]）[name =user [password1]]' ，真
  

I want to ensure that the password fields are empty when editing a user. How do I do this in a functional test?

I've tried both of these variants:

assert_select "input[name=?][value=?]", 'user[password1]', ''

and

assert_tag :tag => "input", :attributes => {:name => "user[password1]", :value => ""}

Both fail because there is no value= attribute present in the generated html. I don't see any way of testing that an attribute is not present in the generated html?

解决方案

Try this:

assert_select 'input:not([value])[name="user[password1]"]', true
