Silverstripe测试未为元素注入配置

// Config.php
class Config {
    private $settings;

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

    public function getSetting($key) {
        return $this->settings[$key] ?? null;
    }
}

// Service.php
class Service {
    private $config;

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

    public function doSomething() {
        $setting = $this->config->getSetting('importantSetting');
        // 使用配置进行操作
    }
}

// ServiceTest.php
use PHPUnit\Framework\TestCase;

class ServiceTest extends TestCase {
    public function testDoSomething() {
        $config = new Config(['importantSetting' => 'value']);
        $service = new Service($config);

        // 断言或其他测试逻辑
    }
}
