rspec users - Jan 2009 - [Cucumber, Webrat] I should see behaves strangely with html

Hi,

In my tests, I check to see if a given html tag such as
<title>...</title> has the expected value, sometimes it works
sometimes
it tells me it couldn''t find the string, although I see it printed out
in the error screen.

I think it comes form the fact that double-quotes are escaped and
slashes too, and some other strange behavior with spaces and dashes, but
I am not sure about that.

How do you get round this problem?

Can you please post the contents of your step definition?

I don''t have any step definition, I simply use: Then I should see 
"<title>Hello world</title>, its definition is in
webrat_steps.rb

However yesterday I looked in the code of a project (mephistoblog was 
it?), and I noticed that they have: config.gem ''nokogiri'' in 
environement.rb. I don''t have it, is it compulsory for correctly
parsing
the response body?

I don''t have config.gem ''nokogiri'' in
environement.rb, but I do have the
gem installed.

Here is the step definition:
Then /^I should see "(.*)"$/ do |text|
  response.body.should =~ /#{text}/m
end

That works pretty much the same way you would use it in RSpec. I don''t 
see any webrat methods (please correct me if I am mistaken).

I think what might be tripping you up is that this step definition just 
puts whatever is in quotes into a Regex. I personally think we should 
avoid having a Regex in a step because most business users don''t 
understand them. So I often change this matcher to be

Then /^I should see "(.*)"$/ do |text|
  response.body.should =~ /#{Regexp.escape(text)}/m
end

I suggest you either try that step matcher, or you make sure your step 
is properly escaping any special Regex characters. Perhaps this:
  Then I should see "\<title\>Hello world\<\/title\>"

I believe that it prints out the regex used if response.body.should =~ 
/#{text}/m fails. If you still can''t get it to work, pasting the entire
output of you test here (maybe use Pastie.org)

Caveat: I am running version 0.1.13 so it is possible things have 
changed.

HTH

IMO this should be the default,
