Undefined variable in controller I am trying to test with phpunit in laravel

I am trying to learn the basics of unit testing and I am using phpunit and laravel

Here is my controller

FatController.php

class FatController extends BaseController {

    public $result;

    public function __construct($result)
    {
        $this->result = $result;
    }

    public function getResult()
    {
        return $this->$result;
    }
}

and the test class

FatControllerTest.php

class FatControllerTest extends TestCase {

    /**
     * A basic functional test example.
     * @return void
     */

    public $test;

    public function setUp()
    {
        parent::setUp();
        $this->test = new FatController('100%');
    }

    public function testResult()
    {
        $result = $this->test->getResult();
        $this->assertTrue($result == '100%', 'message');
    }
}

As far as I know when the test runs it should create a new variable $test which is equal to a new instance of FatController with a value of 100%

It then runs $test FatController Method getResult which should return $result which has been defined by the constructor as '100%'

When the test runs however I get this

PHP Warning:  Uncaught exception 'ErrorException' with message 'Undefined variable: result' in /Users/irish/Dropbox/www/youtube/app/controllers/FatController.php:15
Stack trace:

PHP Fatal error:  Cannot access empty property in /Users/irish/Dropbox/www/youtube/app/controllers/FatController.php on line 15

So I understand that $result is not being defined as anything and that is causing an error when getResult tries to return it but I don't know what I have done wrong

It looks like you have a typo. return $this->$result; should be return $this->result;.
