        Detailed documentation
        **********************
        
        Test Setup
        ----------
        
        Most API methods will only return True or False,
        to get a more verbose output and prohibit
        making requests to Silverpop
        We monkeypatch urllib to print
        (url, headers, data) instead of doing any requests.
        
        We create a Fake class to be returned by urlib2.urlopen,
        which will always return a successful silverpop response::
        
        >>> class Fake(object):
        ...     def read(self): return "<success>true</success>"
        
        In our test method, we print request's url, headers, data (we decode
        the urlencoded data for the test) and
        return a Fake object::
        
        >>> import cgi
        >>> def test_urlopen(req):
        ...     print '-'*30 + 'request details' + '-'*30
        ...     print req.get_full_url()
        ...     print req.headers
        ...     xml = dict(cgi.parse_qsl(req.data))['xml']
        ...     print xml
        ...     print '-'*75
        ...     return Fake()
        >>> import urllib2
        
        Finally we patch urllib2.urlopen::
        
        >>> urllib2.urlopen = test_urlopen
        
        We also define a FakeRequest class to define our request
        containing just a form::
        
        >>> class FakeRequest(dict):
        ...   def __init__(self, **kwargs):
        ...     self.form = kwargs
        
        API Methods
        -----------
        
        All api methods can be accessed by importing the module::
        
        >>> import silverpop
        
        
        First, we define data needed for the various api_methods.
        
        The URL of the Silverpop Server::
        
        >>> api_url = 'http://api1.silverpop.com/XMLAPI '
        
        A List Id::
        
        >>> list_id = 999
        
        An Email Address (we only support email key lists, so this is
        our key identifying a newsletter subscriber)::
        
        >>> email = 'my@email.com'
        
        add_recipient
        +++++++++++++
        
        
        Let's call the add_recipient api with the required attributes::
        
        >>> silverpop.add_recipient(api_url, list_id, email)
        ------------------------------request details------------------------------
        http://api1.silverpop.com/XMLAPI
        {'Content-type': 'application/x-www-form-urlencoded;charset=UTF-8'}
        <Envelope>
        <Body>
        <AddRecipient>
        <LIST_ID>999</LIST_ID>
        <CREATED_FROM>2</CREATED_FROM>
        <UPDATE_IF_FOUND>true</UPDATE_IF_FOUND>
        <COLUMN>
        <NAME>EMAIL</NAME>
        <VALUE>my@email.com</VALUE>
        </COLUMN>
        </AddRecipient>
        </Body>
        </Envelope>
        ---------------------------------------------------------------------------
        True
        
        If we provide a list of columns, these will be used in the request, leading to columns in silverpop.
        
        For example, we want to use a custom column **gender**::
        
        >>> columns = [{'column_name': 'gender', 'column_value': 'male'}, ]
        
        >>> silverpop.add_recipient(api_url, list_id, email, columns)
        ------------------------------request details------------------------------
        http://api1.silverpop.com/XMLAPI
        {'Content-type': 'application/x-www-form-urlencoded;charset=UTF-8'}
        <Envelope>
        <Body>
        <AddRecipient>
        <LIST_ID>999</LIST_ID>
        <CREATED_FROM>2</CREATED_FROM>
        <UPDATE_IF_FOUND>true</UPDATE_IF_FOUND>
        <COLUMN>
        <NAME>EMAIL</NAME>
        <VALUE>my@email.com</VALUE>
        </COLUMN>
        <COLUMN>
        <NAME>gender</NAME>
        <VALUE>male</VALUE>
        </COLUMN>
        </AddRecipient>
        </Body>
        </Envelope>
        ---------------------------------------------------------------------------
        True
        
        update_recipient
        ++++++++++++++++
        
        **update_recipient** works similar as **add_recipient**,
        but offers to change the recipient's email address, and re-opt-in
        an opted out recipient in addition.
        for our first test, we are not going to do that::
        
        >>> old_email = 'my@email.com'
        
        Let's call the update_recipient api with the required attributes::
        
        >>> silverpop.update_recipient(api_url, list_id, old_email)
        ------------------------------request details------------------------------
        http://api1.silverpop.com/XMLAPI
        {'Content-type': 'application/x-www-form-urlencoded;charset=UTF-8'}
        <Envelope>
        <Body>
        <UpdateRecipient>
        <LIST_ID>999</LIST_ID>
        <CREATED_FROM>2</CREATED_FROM>
        <OLD_EMAIL>my@email.com</OLD_EMAIL>
        </UpdateRecipient>
        </Body>
        </Envelope>
        ---------------------------------------------------------------------------
        True
        
        If we provide a list of columns, these will be used in the request, leading to columns in silverpop.
        This is also used to change the recipient's email address.
        
        For example, we want to change the **email address**, therefore we need to specify one column **EMAIL**::
        
        >>> columns = [{'column_name': 'EMAIL', 'column_value': 'new@email.com'}, ]
        
        >>> silverpop.update_recipient(api_url, list_id, old_email, columns)
        ------------------------------request details------------------------------
        http://api1.silverpop.com/XMLAPI
        {'Content-type': 'application/x-www-form-urlencoded;charset=UTF-8'}
        <Envelope>
        <Body>
        <UpdateRecipient>
        <LIST_ID>999</LIST_ID>
        <CREATED_FROM>2</CREATED_FROM>
        <OLD_EMAIL>my@email.com</OLD_EMAIL>
        <COLUMN>
        <NAME>EMAIL</NAME>
        <VALUE>new@email.com</VALUE>
        </COLUMN>
        </UpdateRecipient>
        </Body>
        </Envelope>
        ---------------------------------------------------------------------------
        True
        
        Another common use case is to to re-opt-in an opted-out recipient.
        
        Therefore we provide a column **OPT_OUT**, which when set to **False**
        will re-opt-in the recipient::
        
        
        >>> columns = [{'column_name': 'OPT_OUT', 'column_value': 'False'}, ]
        
        >>> silverpop.update_recipient(api_url, list_id, old_email, columns)
        ------------------------------request details------------------------------
        http://api1.silverpop.com/XMLAPI
        {'Content-type': 'application/x-www-form-urlencoded;charset=UTF-8'}
        <Envelope>
        <Body>
        <UpdateRecipient>
        <LIST_ID>999</LIST_ID>
        <CREATED_FROM>2</CREATED_FROM>
        <OLD_EMAIL>my@email.com</OLD_EMAIL>
        <COLUMN>
        <NAME>OPT_OUT</NAME>
        <VALUE>False</VALUE>
        </COLUMN>
        </UpdateRecipient>
        </Body>
        </Envelope>
        ---------------------------------------------------------------------------
        True
        
        opt_in_recipient
        ++++++++++++++++
        
        This method is a wrapper around update_recipient_data,
        for explicitly opting in a recipient.
        
        Let's call the opt_in_recipient api with the required attributes::
        
        >>> silverpop.opt_in_recipient(api_url, list_id, email)
        ------------------------------request details------------------------------
        http://api1.silverpop.com/XMLAPI
        {'Content-type': 'application/x-www-form-urlencoded;charset=UTF-8'}
        <Envelope>
        <Body>
        <UpdateRecipient>
        <LIST_ID>999</LIST_ID>
        <CREATED_FROM>2</CREATED_FROM>
        <OLD_EMAIL>my@email.com</OLD_EMAIL>
        <COLUMN>
        <NAME>OPT_OUT</NAME>
        <VALUE>False</VALUE>
        </COLUMN>
        </UpdateRecipient>
        </Body>
        </Envelope>
        ---------------------------------------------------------------------------
        True
        
        If we provide a list of columns, these will be used in the request,
        leading to columns in silverpop.
        This can be also used to change the recipient's email address.
        For example, we want to change the **email address**.
        Therefore we need to specify one column **EMAIL**::
        
        >>> columns = [{'column_name': 'EMAIL', 'column_value': 'new@email.com'}, ]
        
        >>> silverpop.opt_in_recipient(api_url, list_id, email, columns)
        ------------------------------request details------------------------------
        http://api1.silverpop.com/XMLAPI
        {'Content-type': 'application/x-www-form-urlencoded;charset=UTF-8'}
        <Envelope>
        <Body>
        <UpdateRecipient>
        <LIST_ID>999</LIST_ID>
        <CREATED_FROM>2</CREATED_FROM>
        <OLD_EMAIL>my@email.com</OLD_EMAIL>
        <COLUMN>
        <NAME>OPT_OUT</NAME>
        <VALUE>False</VALUE>
        </COLUMN>
        <COLUMN>
        <NAME>EMAIL</NAME>
        <VALUE>new@email.com</VALUE>

        </UpdateRecipient>
        </Body>
        </Envelope>
        ---------------------------------------------------------------------------
        True
        
        If the user specifies an **OPT_OUT** column, this will be ignored,
        as we always want to opt in.
        
        Let's define the to be ignored column::
        
        >>> columns = [{'column_name': 'OPT_OUT', 'column_value': 'some value'}, ]
        
        Notice how the value of **OPT_OUT** is still **False**::
        
        >>> silverpop.opt_in_recipient(api_url, list_id, email)
        ------------------------------request details------------------------------

        True
        
        opt_out_recipient
        +++++++++++++++++
        
        Let's call the opt_out_recipient api with the required attributes::
        
        >>> silverpop.opt_out_recipient(api_url, list_id, email)
        ------------------------------request details------------------------------
        http://api1.silverpop.com/XMLAPI

        ---------------------------------------------------------------------------
        True
        
        is_opted_in
        +++++++++++
        
        This method returns **True** when the specified email is a
        non-opted out recipient of a list.
        If the list doesn't exist, or
        the user isn't a recipient of an existing list, or
        the user is opted out form the specified list,
        it should return **False**.
        
        For this test we need to interpret the various responses,
        which we could get from silverpop, so we are going to change
        in more detail, so we change our Fake class simulating, the different Silverpop
        responses.
        
        First, we assume that we have specified a non existing list_id
        (is_opted_in should return False)::

        For this test, we want to have a simple xml as reply from Silverpop,
        as we don't process the response further::

        ...     def read(self): return "<silverpop_response>true</silverpop_response>"

        If we provide a column, this will be used in the request
        (use for non email key lists only).
        
        
        For example, we have a custom key **USER_ID**::

        The Silverpop XML API offers a quite large variaty of commands,
        of which we only implement a subset.
        If you need to make different requests you can use this method to
        submit custom xml to Silverpop. As result, you will get the Silverpop
        Response, which is also xml.
        
        Imagine, we want to use the **ForwardToFrient** xml command.
        
        Let's define the custom xml::
        
        >>> xml = """<Envelope>
        ...   <Body>
        ...     <ForwardToFriend>
        ...       <SENDER_EMAIL>bob@bob.com</SENDER_EMAIL>
        ...       <r>5</r>
        ...       <m>10</m>
        ...       <RECIPIENTS>jane@jane.com</RECIPIENTS>
        ...       <MESSAGE>Forwarded: Check this out, I just got that</MESSAGE>
        ...     </ForwardToFriend>
        ...   </Body>
        ...  </Envelope>"""
        
        The xml is sent to Silverpop and we get the response back, for further processing::
        
        >>> silverpop.xml_request(api_url, xml)
        ------------------------------request details------------------------------
        http://api1.silverpop.com/XMLAPI
        {'Content-type': 'application/x-www-form-urlencoded;charset=UTF-8'}
        <Envelope>
        <Body>

        <MESSAGE>Forwarded: Check this out, I just got that</MESSAGE>
