我应该如何让webrat测试文本区域的内容

Question

我正在努力找出正确的语法，让webrat检查表单中文本区域的内容。

我可以用检查文本区域的存在

response.should have_selector('textarea')

但是CCD_ 1方法似乎仅检查响应中的可见文本。有一些水豚方法可以检查文本区域的内容，但我正在为水豚制定一套现有的大型规范，这些规范似乎都在WebRat中，当我尝试使用像have_field这样的水豚方法时，我不断收到以下错误：

RSpec::Expectations::ExpectationNotMetError Exception: expected field "textarea" to return something

我发现了这样的例子：

response.should have_selector('textarea', :content => 'blah')

但奇怪的是，这导致调试器继续运行，而我还没能有效地将其作为解决方案进行测试。

任何关于正确方法的提示或建议都非常感谢

这是我在调试器中测试的堆栈

(rdb:1) p response.should have_selector('textarea#article_body_and_extended', :content =>  text)

然后调试器继续，检查失败：

text = @article.body + @article_for_merging.body + "n&lt;<!--more-->&gt;n" [e-mail]
debugger
response.should have_selector('textarea#article_body_and_extended', :content =>  text)

即使当我在响应体上执行regex时，我也会得到匹配的

(rdb:1) p text
"A content with several datasomething we will merge&lt;<!--more-->&gt;extended content for fun"
(rdb:1) p response.body =~ text
TypeError Exception: type mismatch: String given
(rdb:1) p response.body =~ /text/
218

我真正想要的是一种将文本区域的实际内容提取出来的方法。。。虽然我觉得我应该写一个模型规范而不是控制器规范。。。

Answer 1

所以我有点放弃了让它工作。我想我找到了正确的语法如下：

response.should have_selector('textarea', :name => "article[body_and_extended]",:content =>  text)

其中我已将文本设置为预期内容。我花了一个小时检查我是否准确地掌握了文本区域中的文本，但无法使其工作——可能是编码问题或其他什么问题。然而，有效的是：

text = @article.body + @article_for_merging.body + "n<!--more-->n" [e-mail]+@article_for_merging.extended
position = response.body =~ /#{Regexp.quote(text)}/
position.should_not be_nil

所以我想继续前进，稍后再回来。。。
