Question

I’m trying to work out the right syntax to have webrat check the contents of a textarea in a form.

I can check the presence of a textarea with

response.should have_selector('textarea')

but the contains method appears to only check the visible text in the response. There are capybara methods for checking the contents of a textarea, but I’m working on a large existing set of specs for Capybara, which appear to all be in WebRat, and when I try to use Capybara methods like have_field I keep getting the following error:

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

I’ve found examples that do things like the following:

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

but strangely this causes by debugger to continue and I haven’t been able to test it effectively as a solution yet.

Any tips or advice on the correct approach much appreciated

here’s the stacktrace I get testing in the debugger

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

and then the debugger continues and the check fails:

    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)

even though when I do a regex on the response body I get a match

(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

what I’d really like is a way just to pull that actual content of the textarea out … although I’m getting the sense I should be writing a model spec instead of a controller spec …

Answer 1

so I’ve kind of given up on getting this working. I think I tracked down the right syntax as this:

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

where I’ve set text to be the expected content. I spend a good hour checking that I had precisely the text that was in the textarea, but couldn’t make it work – maybe an encoding issue or something. However what does work is this:

    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

so I tempted to move on and come back to this later …
