Hi,
Testing the view of an application with functional tests, how would one
go about checking that there are a certain number of <span> elements
present on a page, which all belong to a certain class.
I tried:
assert_select "form" do
assert_select "span", :class=> "required_field",
:count => 13
end
But this just found all of the span elements on the page and returned
false.
Grateful as ever for any help.

If that _still_ doesn''t work, throw away assert_xhtml, and drop down raw XPath thru Nokogiri to do it. (gem install rkelly nokogiri assert2, and require ''assert2/xhtml'', to get assert_xhtml, IIRC..) -- Phlip
Thanks for the answers
I just looked again at the html rails is generating and in fact the
element I''m looking for looks like this:
<span title="required field">*</span>
not:
<span class="required_field">*</span>
Would I test for this like so:
assert_select "form" do
assert_select("span.title.required field", :count => 13)
end
When I run it, I get the error message:
Expected at least 13 elements matching "span.required_field", found 0.
I installed the recommended gem and using that the test works just fine:
assert_xhtml do
form :xpath! => ''count(.//span[ @title= "required
field" ]) =
13''
end
One question however, is there any way to turn off the "...in this
sample..." aspect of the output, as if the does find any errors, it
returns my entire html page.
E.g.
1) Failure:
test_index_view(FormControllerTest)
[c:/ruby/lib/ruby/gems/1.8/gems/assert2-0.5.3/lib/assert2/xhtml.rb:327:in
`assert_xhtml''
/test/functional/form_controller_test.rb:41:in `test_index_view''
/test/functional/form_controller_test.rb:37:in `test_index_view'']:
Could not find this reference...
<form xpath!="count(.//span[ @class = "required field"
]) =
13"></form>
...in this sample...
300 lines of html follow

To do what you want with assert_select you can use assert_select "form>span[title=required field]", 13 That is there should be 13 span elements with given title inside form elements or assert_select "form" do assert_select "span[title=required field]", 13 end if you want to insist that all 13 are in the same form Colin 2009/5/20 Jim Burgess <rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org>> > Thanks for the answers > > I just looked again at the html rails is generating and in fact the > element I''m looking for looks like this: > > <span title="required field">*</span> > > not: > > <span class="required_field">*</span> > > Would I test for this like so: > > assert_select "form" do > assert_select("span.title.required field", :count => 13) > end > > When I run it, I get the error message: > Expected at least 13 elements matching "span.required_field", found 0. > > I installed the recommended gem and using that the test works just fine: > > assert_xhtml do > form :xpath! => ''count(.//span[ @title= "required field" ]) > 13'' > end > > One question however, is there any way to turn off the "...in this > sample..." aspect of the output, as if the does find any errors, it > returns my entire html page. > > E.g. > > 1) Failure: > test_index_view(FormControllerTest) > > [c:/ruby/lib/ruby/gems/1.8/gems/assert2-0.5.3/lib/assert2/xhtml.rb:327:in > `assert_xhtml'' > /test/functional/form_controller_test.rb:41:in `test_index_view'' > /test/functional/form_controller_test.rb:37:in `test_index_view'']: > > Could not find this reference... > > > <form xpath!="count(.//span[ @class = "required field" ]) > 13"></form> > > > ...in this sample... > > 300 lines of html follow > -- > Posted via http://www.ruby-forum.com/. > > > >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
