internal server error when using 'visit' with rails 2.2 and test::unit

Reported by Jeroen van Dijk | December 10th, 2008 @ 11:44 AM

I'm not sure if whether I found a bug or I'm misunderstanding how webrat should be instantiated.

I'm having the following code in a test unit file


ENV["RAILS_ENV"] = "test"
require File.expand_path(File.dirname(__FILE__) + "/../config/environment")
require 'test_help'
require "webrat/rails"

class WebratTest < ActionController::IntegrationTest

  def test_webrat
    visit "/"
    assert false
  end
end

When using autotest I'm getting the error output below. It seems to hang on line 294 (/Library/Ruby/Gems/1.8/gems/actionpack-2.2.2/lib/action_controller/integration.rb:294):


# Inject status back in for backwords compatibility with CGI
@headers['Status'] = @status

Did i forget something or is this a bug in webrat caused by 2.2?

Regards, Jeroen

    Which version of webrat did you use? Github, gem?

    With the newest webrat from github on master you would now do:

    
ENV["RAILS_ENV"] = "test"
require File.expand_path(File.dirname(__FILE__) + "/../config/environment")
require 'test_help'
require "webrat"

Webrat.configure do |config|
  config.mode = :rails
end

class WebratTest < ActionController::IntegrationTest

  def test_webrat
    visit "/"
  end
end

    Please try that out with the new webrat and let us know how it went.

    I had that problem with after upgrading to 0.4.1 on Rails 2.2.2. The configure & etc did the trick.

    • State changed from “new” to “invalid”

    I'm going to mark this as invalid, as it appears using the configuration directive solved it.

    Jeroen -- If you're still seeing issues, please add a comment and we'll reopen and get them taken care of.

    Cheers,
