After having a bit of a sleep on it, I realised that the
ControllerTestCase::generate() method also mocks models, and does so in
such a way as to not loose the association with the fixtures.
Lifting code from ControllerTestCase::generate(), the $this->getMock() call
becomes:
$config = ClassRegistry::config('Model');
list($plugin, $name) = pluginSplit('EmailVerification');
$config = array_merge((array) $config, array('name' =>
'EmailVerification'));
$mock = $this->getMock('EmailVerification', array('verifyEmail'),
array($config));
ClassRegistry::removeObject('EmailVerification');
ClassRegistry::addObject('EmailVerification', $mock);
$this->EmailVerification = $mock;
This would probably make a nice convenience method on the CakeTestCase.
