Test views, be true! :)

Why?

you need to test some complex views
and you want to use RSpec2
and assert_select seems is something strange to you
have_tag in rspec-rails are deprecated now
you need a user-firendly output in your error messages

Being true

Install

Add to your Gemfile (in the :test group :) ):

group :test do
  gem 'rspec-html-matchers'
end

Instructions for installing Nokogiri.

Usage

Simple example:

view=&lt;&lt;-HTML
<h1>Simple Form</h1>

<p>

</p>
<p>

</p>

HTML

view.should have_tag('form', :with =&gt; { :action =&gt; '/users', :method =&gt; 'post' }) do
  with_tag "input", :with =&gt; { :name =&gt; "user[email]", :type =&gt; 'email' }
  with_tag "input#special_submit", :count =&gt; 1
  without_tag "h1", :text =&gt; 'unneeded tag'
  without_tag "p",  :text =&gt; /content/i
end

Examples with more description:

tag matching (matches one or more tags):

'<p class="qwe rty">Paragraph</p>'.should have_tag('p')
'<p class="qwe rty">Paragraph</p>'.should have_tag(:p)
'<p class="qwe rty">Paragraph</p>'.should have_tag('p#qwerty')
'<p class="qwe rty">Paragraph</p>'.should have_tag('p.qwe.rty')

'<p class="qwe rty"><strong>Para</strong>graph</p>'.should have_tag('p strong')
'<p class="qwe rty"><strong>Para</strong>graph</p>'.should have_tag('p#qwerty strong')
'<p class="qwe rty"><strong>Para</strong>graph</p>'.should have_tag('p.qwe.rty strong')
# or
'<p class="qwe rty"><strong>Para</strong>graph</p>'.should have_tag('p') do
  with_tag('strong')
end
'<p class="qwe rty"><strong>Para</strong>graph</p>'.should have_tag('p#qwerty') do
  with_tag('strong')
end
'<p class="qwe rty"><strong>Para</strong>graph</p>'.should have_tag('p.qwe.rty') do
  with_tag('strong')
end

special case: classes matching:

# all of this are equivalent:
'<p class="qwe rty">Paragraph</p>'.should have_tag('p', :with =&gt; { :class =&gt; 'qwe rty' })
'<p class="qwe rty">Paragraph</p>'.should have_tag('p', :with =&gt; { :class =&gt; 'rty qwe' })
'<p class="qwe rty">Paragraph</p>'.should have_tag('p', :with =&gt; { :class =&gt; ['rty', 'qwe'] })
'<p class="qwe rty">Paragraph</p>'.should have_tag('p', :with =&gt; { :class =&gt; ['qwe', 'rty'] })

usage with capybara and cucumber:

page.should have_tag( … )

where page is an instance of Capybara::Session

Also included special matchers for form inputs:

and of course you can use the without_ matchers (see the documentation).

More info

You can find more on RubyDoc, take a look at {RSpec::Matchers#have_tag have_tag} method.

Also, please read {file:CHANGELOG.md CHANGELOG}, it might be helpful.
