  24 Setup Helper:
  25   CPK now has a place for your individual testing configuration.
  26   That is, instead of hardcoding it in the Rakefile and test/connections files,
  27   there is now a local/database_connections.rb file that is NOT in the
  28   repository. Your personal DB information (username, password etc) can
  29   be stored here without making it difficult to submit patches etc.
  30
  31 Installation:
  32   i)   cp locals/database_connections.rb.sample locals/database_connections.rb
  33   ii)  For #{adapter} connection details see "Adapter Setup Helper" below.
  34   iii) Rerun this task
  35
  36 #{error_msg_adapter_helper}
  37
  38 Current ENV:
  39   #{ENV.inspect}

  45 Adapter Setup Helper:
  46   To run #{adapter} tests, you need to setup your #{adapter} connections.
  47   In your local/database_connections.rb file, within the ENV['cpk_adapter'] hash, add:
  48       "#{adapter}" => { adapter settings }
  49
  50   That is, it will look like:
  51     ENV['cpk_adapters'] = {
  52       "#{adapter}" => {
  53         :adapter  => "#{adapter}",
  54         :username => "root",
  55         :password => "root",
  56         # ...
  57       }
  58     }.to_yaml
  59         EOS
  60       end
  61     end
  62   end
