Question

I’ve been using for Rails apps I’ve been maintaining the hpricot_matchers and most recently rspec_tag_matchers as matcher implementations to test strings with nested tags inside (like, let’s say, HTML or XML). Specially the last one is really good, since it uses Nokogiri.

Recently I started developing in Sinatra, and of course, I bundled rspec in it. All is nice and neat, til I found out I don’t have certain matchers available like the have_tag (which check tags and attributes values). Well, this would be really great to have in Sinatra, and the above mentioned gems are not usable, since they have a rspec-rails dependency, which has a rails dependency.

So the question would be: is there any tool available for Sinatra which accomplishes the same task? Any Sinatra matchers out in the open? Couldn’t find any, though.

Answer 1

Actually found out an extension that does the job…

Should have looked a little bit more. I haven’t checked whether it covers everything that the rails rspec matcher helpers do, but most of the important ones are there, including the very valuable have_tag. One thing, though: the specification for both is a bit different when it comes to nested conditions in sub-tags:

rspec_tag_matchers(rails3):

text.should have_tag("p") do |paragraph|
  paragraph.should have_tag("strong")
end

rspec_html_matchers(sinatra/…):

text.should have_tag("p") do 
  with_tag("strong")
end
