mainline

DESCRIPTION:

Mainline is a rails plugin which exposes your rails app via webrick to allow testing with browser automators such as Selenium or Watir. Mainline allows your rails actions to run in the same transaction as your unit tests so you can use fixtures, factories, or whatever.

SYNOPSIS:

Currently mainline only supports one integration session at a time.

To install it as a plugin:

script/plugins install git://github.com/gaffo/mainline.git

And to enable it you need to do a:

Mainline.enable, or the block form (if you need to configure things).

For example, to enable Mainline and specify a port:

Webrat.configure do |config|
  config.mode = :rails
  config.open_error_files = false # Set to true if you want error pages to pop up in the browser
  Mainline.enable { |config| config.port = 3030 }
end

When using webrat, it's best to do somthing like this if you are just running selenium.

Webrat.configure do |config|
  config.application_framework = :external
  Mainline.enable
end

However if you need to run in selenium and non selenium and need to configure ports (for build boxes), you should use somthing like this (pulled from my own config):

Webrat.configure do |config|
  if ENV['WEBRAT_INTEGRATION_MODE'] == 'selenium'
  	config.mode = :selenium
    config.application_framework = :external
    config.application_port = ENV['WEBRAT_APPLICATION_PORT'] || 3001
    config.selenium_server_port = ENV['WEBRAT_SELENIUM_PORT'] || 4444
    Mainline.enable do |mainline_config|
      mainline_config.port = ENV['WEBRAT_APPLICATION_PORT'] || 3001
    end
  else
  	config.mode = :rails
  end
end
