Mollie-Bank 
A simple implementation of the "TM Bank" by Mollie, but without the portforward stuff to test your iDeal transactions localy.
Getting started
Install
To install the gem you should execute
gem install mollie-bank
Running the Mollie Bank
After installation you can simple run:
mollie-bank
Check if it works by browsing to: http://localhost:4567/
Howto implement
By default all communication for iDeal transactions is through https://secure.mollie.nl/xml/ideal. To use the "Mollie Bank" gem, you have to change this path into http://localhost:4567/xml/ideal.
Of course you only want to use this in development mode, so you have to create some code to change this path only when it isn't in production mode.
Check the Wiki: Implement into existing modules page for implementation of existing frameworks/modules.
