Error Testing a view in RSpec 2

Testing RSpec
1

Well, I’be looking for test my views with rspec, looking the
documentation at http://rspec.info/rails/writing/views.html we see
some examples, in RSpec 2 the response was deprecated and now I’m
using the rendered instead, but this code

describe “tags/search.html.erb” do
it “should be have an p when no company for the tag was found” do
assigns[:name] = “Teste”
render
rendered.should have_tag(‘h4’, “Visualizando empresas pela Tag
Teste”)
end
end

and I get :

Failures:

  1. tags/search.html.erb should be have an p when no company for the
    tag was found
    Failure/Error: rendered.should have_tag(‘h4’, “Visualizando
    empresas pela Tag Teste”)
    undefined method `has_tag?’ for #String:0x7f45cc59a880

    ./spec/views/tags/search.html.erb_spec.rb:9

I don’t know what method we use to check my views?

thanks for all
regards

If you’re using webrat, use have_selector or have_xpath. Otherwise, use
Rails’ assert_select.

Changing my test, for user assert_select, an new error is raised

it “should be have an p when no company for the tag was found” do
assigns[:name] = “Teste”
render
rendered.should assert_select(‘h4’, “Visualizando empresas pela
Tag”)
end

And the error:

Failures:

  1. tags/search.html.erb should be have an p when no company for the
    tag was found
    Failure/Error: rendered.should assert_select(‘h4’, “Visualizando
    empresas pela Tag”)
    undefined method `matches?’ for #Array:0x7f41afa22388

    ./spec/views/tags/search.html.erb_spec.rb:7

thanks for response

Please post inline or at the bottom. It makes it easier to follow the
conversation. I moved your post to the bottom:

assert_select is a Rails assertion that works by itself, not an RSpec
matcher. Use it like this:

assert_select(‘h4’, “Visualizando empresas pela Tag”)

Woah, now works the test, thanks for response. Why the have_tag has
removed from RSpec 2?

have_tag wrapped assert_select in a way that was very brittle. Also
Webrat and Capybara matchers are better :slight_smile:

Any tips on how we can use the Capybara matchers in our helper specs?
Seems like a reasonable thing to want to do, since helpers are typically
used to put together pieces of html.

Capybara does not support them yet. It’s in the works though. Check the
Capybara tracker for more info.

I had to move your post again. Please post inline or at the bottom.

if you want to test views with have_tag and rspec2 try this gem:
