Response header and flickering test

[beagile]

Hello Guys,

I've got the following cucumber step (which uses capybara and capybara-webkit under the hood) that sometimes works and sometimes not:

Then /^I can download a file$/ do

    page.response_headers['Content-Disposition'].should include('attachement') unless @selenium

end

It seems as if page.response_headers is sometimes present and sometimes not. If not I get the following error:

undefined method `include?' for nil:NilClass (NoMethodError

Does anybody know how to fix this?

Cheers,

Govinda

See if page.response_headers is nil with an explicit test and then see if that particular header is present or not.

I'm guessing sometimes that particular header is not present (as oppose to all of the headers).

That might give you a clue which way to debug this.

OK. In the end I fixed by changing my step like this

Then /^I can download a file$/ do 

Timeout.timeout(20) do 

                sleep 0.1 if page.response_headers['Content-Disposition'].nil?

              end

              page.response_headers['Content-Disposition'].should include('attachement') unless @selenium

            end
