CakePHP 2.2.5 には、アプリの支払いを処理するコンポーネントがあります。ブラウザ/通常のセッションからコンポーネント内で関数「addPayment」を正常に実行できますが、テスト ケースで実行すると失敗します。

$this->controller->Product->getDataSource();コンポーネント内でトランザクションを初期化すると、「オブジェクト以外のプロパティを取得しようとしています」というエラーが表示されます。

コンポーネントに設定されているように見える$this->controllerか、設定されていません。$this->controller->Productそれが機能するように修正する方法はあります$this->controller->Product->getDataSource();か？

App::uses('ComponentCollection', 'Controller');

class TestFinanceController extends Controller {
