$body   = '{"error":"missing","reason":"problem?"}';

$client = new Zend_Http_Client;
$client->setAdapter(new Zend_Http_Client_Adapter_Test);

$couchdb = $this->getMock(
    array($userId, $this->config,)
    ->will($this->returnValue(new Zend_Http_Response(200, array(), $body)));

Example code

Consider the following example:

My objective is not to be able to test any of the protected methods directly, but to be able to supply a fixture so we don't have to setup CouchDB to run our testsuite. My fixture would replace makeRequest() and return a JSON string instead.
