I’m writing a cucumber test for an xml webservice. When making POST’s
the Content-Type in the header is set to “application/xml” and for any
request, the Accept header is set to “application/xml” (aka
Mime::XML.to_s)
I’m running into the following issue:
When I make two successive requests, the first one being a POST to log
the user in; the second one a GET to retrieve some data, the second
request always seems to fail with this error:
private method `split' called for #<Mime::Type:0x7f60a708ff70>
(NoMethodError)
/usr/lib/ruby/gems/1.8/gems/actionpack-2.3.2/lib/action_controller/mime_type.rb:206:in
method_missing' /usr/lib/ruby/gems/1.8/gems/rack-1.0.0/lib/rack/request.rb:51:inmedia_type’

request_parameters' /usr/lib/ruby/gems/1.8/gems/actionpack-2.3.2/lib/action_controller/request.rb:381:inparameters’
This started happening only in Rails 2.3. It previously worked fine
with Rails 2.0
Now, I dug into this some more; the Session class in webrat core seems
to get instantiated once for the entire scenario and the instance sticks
around for all of the requests. I noticed by checking with the
debugger, that the header object gets transformed into a Rack header
object and acquires things like the referrer field from the first
request. On the second request (the GET), the Content-Type is set but
it probably shouldn’t–as there is no payload data, it’s a GET–and that
causes havoc. I’m kind of lost as to whether this is a bug in Rack or
Rails or Webrat or whether I’m doing something wrong.
Any advice is appreciated.
