Unit Testing OAuth Login with Cake 2.3 - unit-testing

Question

I need some advice on how to set up a unit test in Cake 2.3 that tests OAuth login. I'm using the thomseddon/cakephp-oauth-server plugin. Note: I've reviewed examples such as CakePHP 2.3 - Unit testing User Login, but I'm still confused about how exactly to approach an OAuth test using the plugin. Any help appreciated.
The following is what I currently have in my unit test. Not very much of a test, yet.
/**
* testOAuthLogin method
* Tests that OAuth login works
* #return void
*/
public function testOAuthLogin(){
$data = array(
'response_type' => 'code',
'client_id' => getenv('THREE_SCALE_APP_ID'),
'User' => array(
'username' => TEST_USERNAME,
'passwd' => TEST_PASSWORD
)
);
$result = $this->testAction('/oauth/login', array(
'data' => $data,
'method' => 'post'
));
debug($result);
}
This returns:
{"error":"invalid_client","error_description":"No client id supplied"}

Answer 1

I was able to figure this out. I just needed to setup up proper fixtures for User and AccessToken. And then I had to ensure that these were imported in the controller that I was testing in via $fixtures.
Example of my AccessTokenFixture:
<?php
App::uses('OAuthComponent', 'OAuth.Controller/Component');
/**
* AccessTokenFixture
*
*/
class AccessTokenFixture extends CakeTestFixture {
/**
* Fields
*
* #var array
*/
public $fields = array(
'oauth_token' => array('type' => 'string', 'null' => false, 'default' => null, 'length' => 40, 'key' => 'primary', 'collate' => 'utf8_general_ci', 'charset' => 'utf8'),
'client_id' => array('type' => 'string', 'null' => false, 'default' => null, 'length' => 36, 'collate' => 'utf8_general_ci', 'charset' => 'utf8'),
'user_id' => array('type' => 'integer', 'null' => false, 'default' => null),
'expires' => array('type' => 'integer', 'null' => false, 'default' => null),
'scope' => array('type' => 'string', 'null' => true, 'default' => null, 'collate' => 'utf8_general_ci', 'charset' => 'utf8'),
'indexes' => array(
'PRIMARY' => array('column' => 'oauth_token', 'unique' => 1)
),
'tableParameters' => array('charset' => 'utf8', 'collate' => 'utf8_general_ci', 'engine' => 'MyISAM')
);
/**
* init method
* #return void
*/
public function init() {
$this->records = array(
array(
'oauth_token' => OAuthComponent::hash('SAMPLE_ACCESS_TOKEN'),
'client_id' => 'YOUR_CLIENT_ID',
'user_id' => 1,
'expires' => 1367263611232323,
'scope' => ''
),
array(
'oauth_token' => OAuthComponent::hash('SAMPLE_ACCESS_TOKEN'),
'client_id' => 'YOUR_CLIENT_ID',
'user_id' => 2,
'expires' => 13672640632323323,
'scope' => ''
)
);
parent::init();
}
}
