无法设置夹具（带有 dbunit 的 PHPunit）
fails to set up fixture (PHPunit with dbunit )
正在尝试为我的 Phalcon 测试设置固定装置，但失败了。
你能找出我的实现出了什么问题吗？
用法
- phalcon 7.2
- Docker 版本 18.09.0-ce-beta1
- docker-compose版本1.22.0
- phpunit6.5.8
- dbunit 3.0.3
当前状态
使用"getConnection"函数连接数据库成功
创建数据集（YAML 类型）
创建 getDataSet 函数，但无法设置夹具和清理

数据集
testRow:
-
id: 1
name: 'test'
text: 'hello, world'
回应
Failed asserting that 0 matches expected 1.
备注
当我在 getConnection 中使用真正的 mysql 数据库连接并调用 $this->getConnection()->getRowCount('testRow') 时，结果是正确的。
因此，问题似乎来自加载 yaml 数据集

Dbunit 必须执行一些设置操作，它们在 PHPUnit\DbUnit\TestCaseTrait 中的 setUp() 方法中定义（您可以看到更多 code details here。当您继承 PHPUnit\DbUnit\TestCase 时，您大多不必担心它（除了确保从您的测试用例中调用 parent::setUp() 之外）。当直接从特征中使用功能时，您必须确保也调用了 dbunit 的设置。
您可以通过以下方式实现此目的：
<?php
use Phalcon\Test\UnitTestCase as PhalconTestCase;
use PHPUnit\DbUnit\TestCaseTrait;
abstract class UnitTestCase extends PhalconTestCase
{
use TestCaseTrait {
setUp as protected dbunitSetUp;
};
public function setUp()
{
parent::setUp(); // phalcon setup
$this->dbuintSetUp(); // dbunit setup
}
}
对于上面的示例，仅包含与问题相关的行，跳过 getConnection 等其他内容
