(I swear I had something like that before and it didn't work!) Here's the solution:
$userId = 61382; $docId = 'CLD2_62e029fc-1dae-4f20-873e-69facb64a21a'; $body = '{"error":"missing","reason":"problem?"}'; $client = new Zend_Http_Client; $client-setAdapter(new Zend_Http_Client_Adapter_Test); $couchdb = $this-getMock('CouchDB', array('makeRequest',), array($userId, $this-config,)); $couchdb-expects($this-once()) -method('makeRequest') -will($this-returnValue(new Zend_Http_Response(200, array(), $body))); $couchdb-setHttpClient($client); $couchdb-getDocument($docId);--- Original blog entry ---
I wrote a couple tests for a small CouchDB access wrapper today. But when I wrote the implementation itself, I realized that my class setup depends on an actual CouchDB server being available and here my journey began.
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.
... more after the jump.
