 * - `method` POST or GET. Defaults to POST.

 * - `return` Specify the return type you want. Choose from:

 *     - `vars` Get the set view variables.

 *     - `view` Get the rendered view, without a layout.

 *     - `contents` Get the rendered view including the layout.

 *     - `result` Get the return value of the controller action. Useful

 * - `models` Models to mock. Models are added to the ClassRegistry so any

 * - `components` Components to mock. Components are only mocked on this controller

 *   and not within each other (i.e., components on components)

 *

 * @param string $controller Controller name

 * @param array $mocks List of classes and methods to mock

 * @return Controller Mocked controller
