我试着在WC_VERSION 常数

主要类别：

class WC_Custom_Variable_Products_Dependencies {

    /** minimum WooCommerce version required by this plugin */
    const MINIMUM_WC_VERSION = \'3.7.9\';

    public function __construct() {

        add_action( \'admin_init\', [$this, \'check_wc_version\']);
    }

    protected function check_wc_version() {

         return  version_compare(WC_VERSION, self::MINIMUM_WC_VERSION , \'>=\');
    }
}

测试类别：

 require_once \'includes/class-wc-custom-variable-products-dependencies.php\';

 class WC_Custom_Variable_Products_DependenciesTest extends WP_UnitTestCase {

     public function setUp() {
        parent::setUp();
        $this->class_instance = new WC_Custom_Variable_Products_Dependencies();
     }

     /**
     * Tests the protected functions 
     * 
     * @param Object $method
     * @return bool
     */
    private function makeReflection($method) {

        $reflection = new ReflectionClass(\'WC_Custom_Variable_Products_Dependencies\');
        $protectedMethod = $reflection->getMethod($method);
        $protectedMethod->setAccessible(true);

        return $protectedMethod->invokeArgs($this->class_instance, [\'\']);
    }
    public function test_check_wc_version() {

        $result = $this->makeReflection(\'check_wc_version\');
        $this->assertTrue($result);
    }
}

和PHPunit返回：Use of undefined constant WC_VERSION - assumed \'WC_VERSION\'这是否意味着在测试中没有加载Woocommerce？
