Is there a way to test the methods defined in the 'helper' block
within the sinatra application?
I'm using Rack::Test and following the sinatra documentation on the
sinatrarb site, but I can seem to find anything about testing the
helper methods.

Thanks

Mike

I've asked this question before, and the answer was: Use black box testing.
That is, just simulate get,put,post and delete and check the results using
e.g. Hpricot.

Personally, I sometimes prefer deeper testing.
I've accomplished that by defining get '/test'.

hope this helps

Mike,

I was struggling with this issue as well before, but think I've solved  
it now.

In my spec_helper.rb (using RSpec)  I create a test app:

class MyTestApp < MyApp # the name of your app or S::B

   get '/tests' do
     case params[:engine]
     when 'erb'
       erb(params[:view], :layout => params[:layout] )
     when 'haml'
       haml(params[:view], :layout => params[:layout] )
     else
       params.inspect
     end
   end

end

Then the Test::Unit::TestCase declaration looks like this: (also in  
spec_helper.rb)

class Test::Unit::TestCase
   include Rack::Test::Methods

   # I declare the app value in before blocks in each actual spec file,
   # to prevent confusions between multiple apps (ie: testing with  
options on/off)
   # def app
   #   MyTestApp.new
   # end

   def setup
     Sinatra::Base.set :environment, :test
   end

   def erb_app(view, options = {})
     options = {:layout => '<%= yield %>', :url  => '/
tests' }.merge(options)
     get options[:url], :view => view, :layout =>  
options[:layout], :engine => :erb
   end

   def haml_app(view, options = {})
     options = {:layout => '= yield ', :url  => '/
tests' }.merge(options)
      get options[:url], :view => view, :layout =>  
options[:layout], :engine => :haml
   end

end

Finally, in my tests I just do this:

   it "should return ...." do
     erb_app '<%= name_of_my_helper_method %>'
     last_response.body.should == 'expected result'
   end

This works quite well I would say, and I only wish I had thought about  
it earlier.

Definitely worth a look for some pointers.
