Trouble making rspec-rails 2 work with webrat

Testing RSpec
1

I’m having problems getting rspec-rails 2 request specs to work with
webrat. Any help would be appreciated. Here’s my setup:

ruby 1.9.2p0
rails 3.0.1
rspec-rails 2.1.0
webrat 0.7.2

Here’s the error I’m getting:

$ rspec --backtrace spec/requests/ssl_certificate_requests_spec.rb
F

Failures:

  1. Failure/Error: Unable to find matching line from backtrace stack level too deep # /opt/local/lib/ruby1.9/1.9.1/forwardable.rb:185

Finished in 0.49825 seconds
1 example, 1 failure

Here are snippets of my files:

spec/spec_helper.rb

The following is based on some tips from a cucumber-rails ticket:

require “webrat”
require “webrat/core/matchers”

include Rack::Test::Methods
include Webrat::Methods
include Webrat::Matchers

Webrat.configure do |config|
config.mode = :rack
config.open_error_files = false
end

spec/requests/_spec.rb

require “spec_helper”

describe “” do
it “” do
visit _path

# The following works when uncommented:
#
# get <text>_path
# assert_template '<text>/<text>'

end
end

Thanks,
Pete

This is actually a webrat issue, but it is reported to rspec-rails and
webrat:

I don’t get the stack level too deep but I do get

undefined method `last_response’ for
#RSpec::Core::ExampleGroup::Nested_2:0x9da18cc

Which was supposed to be fixed ages ago.

So did one fix break another?

I have webrat using :rack config

rspec 2.2.0, rspec-rails 2.2.0, webrat 0.7.2, rails 3.0.3

It looks to me like the webrat rack adapter is calling
@session.last_response which is a rack/test call and should work,
Should I report this on the webrat page or rspec???

So someone is not including the rack test stuff, however still don;t
know why it is failing

I’d get rid of all of that stuff from spec_helper. It was guidance from
a cucumber-rails issue, not an rspec issue, and is unnecessary with
rspec. I’d just re-generate it with “script/rails generate
rspec:install”

HTH,

BGTW the spec is very simple…

require ‘spec_helper’

describe “Logins” do
describe “GET /login” do
it “should be able to login” do
get “/login”
p response.body
end
end
end

the undefined method `last_response’ for
#RSpec::Core::ExampleGroup::Nested_2:0x9da18cc

comes from the p response.body

Sorry I may have been unclear…

When using the default spec_helper as generated from a fresh
script/rails generate rspec:install
I get the error…

undefined method `last_response’ for
#RSpec::Core::ExampleGroup::Nested_2:0x9da18cc

This means something is not seeing the Rack Test stuff.

The second error is got when I add

include Rack::Test::Methods

It now sees last_response but doesn’t get a respnose from visit (That
may be a different errror).

So bottom line is using the latest rails/rspec/webrat does not work
out of the box.

Ok adding

include Rack::Test::Methods

to my spec_helper changed the error to

Failure/Error: visit "/"
 No response yet. Request a page first.

It does for me, so something is different between our configurations.

Do you have webrat in the Gemfile?
Is this a controller spec? If so is it in the spec/controllers
directory?

Also, what version of rspec-rails are we talking about?

Hi David,

I am using the current versions of everything rspec
rspec (2.2.0,)
rspec-core (2.2.1)
rspec-expectations (2.2.0)
rspec-mocks (2.2.0,)
rspec-rails (2.2.0)
webrat (0.7.2)
rails(3.0.3)

webrat is in Gemfile…

group :test, :development do
gem ‘webrat’
gem ‘rspec-rails’
end

My spec is meant to be an integration test and as such is in spec/
requests

I have a pretty simple setup, the full source is here…

Thanks for the help, its odd so many people are having issues with
webrat, should I cross post to their group or is this an rspec/webrat/
rails3 issue?

I’m not sure where the issue is yet (most likely rspec), but I was able
to see it by cloning your repo and running the specs.

I was able to get things to work by moving “include Rack::Test::Methods”
into the configure block:

RSpec.configure do |config|
config.include Rack::Test::Methods
…
end

You should not, however, have to do any such thing, so I’ll look into
it and if I can address this in rspec-rails I will and have a bug-fix
release out soon.

Thanks!

David

For others reading this, this was fixed. I was on rspec 2.1.0 and all I
had to do was to upgrade to the latest (2.4.0) and no changes from the
vanilla rspec install spec_helper are required to run Webrat.

Hope to save everyone the 40 minutes I spent not realizing a simple
upgrade fixed it :slight_smile:
