我正在尝试学习单元测试的基础知识，我正在使用 phpunit 和 laravel

这是我的控制器

胖控制器.php

class FatController extends BaseController {

    public $result;

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

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

和测试班

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');
    }
}

据我所知，当测试运行时，它应该创建一个新变量 $test ，它等于 FatController 的新实例，值为 100%

然后它运行 $test FatController Method getResult 应该返回 $result 已由构造函数定义为 '100%'

但是当测试运行时我得到了这个

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

所以我知道 $result 没有被定义为任何东西，当 getResult 尝试返回它时会导致错误，但我不知道我做错了什么

看起来你有一个错字。return $this->$result;应该是return $this->result;。
