php - 使用类常量时忽略 PHPUnit 测试

Question

我正在使用 PHPUnit6.2.2和 zendframework/zend-test3.1.0为 Zend Framework 3 应用程序编写集成测试，并观察以下行为：

当我在测试类中定义一个常量时，例如

use Zend\Test\PHPUnit\Controller\AbstractHttpControllerTestCase;
class FooTest extends AbstractHttpControllerTestCase
{
    const MY_CONST = 123;
}

并在配置文件中使用它，例如

// /config/autoload/test/mymodule.local.php
use Test\Integration\...\FooTest;
return [
    'module' => [
        'my' => [
            'whatever' => [
                'key' => FooTest::MY_CONST
            ]
        ]
    ]
];

测试类被完全忽略。（用 . 检查assertTrue(false)。）当我用FooTest::MY_CONST一个值替换配置文件时，一切都会再次运行。

看起来像一个错误，但我无法找出它是 PHPUnit 中的错误还是Zend\Test. 以前有人观察过这种行为吗？想法，它可能是由什么引起的（为 PHPUnit 或创建错误票证Zend\Test）？
