【问题描述】：

我创建了一个简单的 hello world Magento 2 测试，当我尝试运行测试时出现以下错误：

致命错误：声明 Magento\Framework\TestFramework\Unit\Listener\ReplaceObjectManager::startTest(PHPUnit\Framework\Test $test) 必须兼容 PHPUnit_Framework_TestListener::startTest(PHPUnit_Framework_Test $测试）在 /Applications/MAMP/htdocs/mag221/vendor/magento/framework/TestFramework/Unit/Listener/ReplaceObjectManager.php 第 14 行

这是 phpunit.xml.dist

HelloMessageTest.php

<?php
namespace TestStore\HelloMessage;
use TestStore\HelloMessage;



class HelloMessageTest extends \PHPUnit_Framework_TestCase
{
    /**
     * @var HelloMessage
     */
    protected $helloMessage;

    public function setUp()
    {
        $objectManager = new \Magento\Framework\TestFramework\Unit\Helper\ObjectManager($this);
        $this->helloMessage = $objectManager->getObject('Magestore\HelloMagento\Model\HelloMessage');
        $this->expectedMessage = 'Hello Magento 2! We will change the world!';
    }

    public function testGetMessage()
    {
         $this->assertEquals($this->expectedMessage, $this->helloMessage->getMessage());
    }
}

我使用的是 PHP 7.1.12，Magento 2.2.1。

知道是什么原因造成的吗？

【问题讨论】：

能否分享您的模块测试类代码以及phpunit.xml
我已经更新了测试类代码和phpunit.xml文件的问题
你确定你的测试用例的路径是正确的../../../TestStore/Checkout/HelloMessage/Test/Unit in phpunit.xml？

标签： magento phpunit magento2

【解决方案1】：

首先创建HelloMessage类\app\code\TestStore\Hello\Model\HelloMessage.php

<?php
namespace TestStore\Hello\Model;

class HelloMessage
{
    public function getMessage()
    {
        return 'Hello Magento 2! We will change the world!';
    }
}

创建单元测试模型\app\code\TestStore\Hello\Test\Unit\Model\HelloMessageTest.php

<?php
namespace TestStore\Hello\Test\Unit\Model;

use TestStore\Hello\Model\HelloMessage;

class HelloMessageTest extends \PHPUnit_Framework_TestCase
{
    /**
     * @var HelloMessage
     */
    protected $helloMessage;

    public function setUp()
    {
        $objectManager = new \Magento\Framework\TestFramework\Unit\Helper\ObjectManager($this);
        $this->helloMessage = $objectManager->getObject('TestStore\Hello\Model\HelloMessage');
        $this->expectedMessage = 'Hello Magento 2! We will change the world!';
    }

    public function testGetMessage()
    {
         $this->assertEquals($this->expectedMessage, $this->helloMessage->getMessage());
    }
}

现在，您必须在 phpunit.xml 中添加 UnitTest by

<testsuite name="Magento Unit Tests">
    <directory suffix="Test.php">../../../app/code/TestStore/Hello/Test/Unit</directory>
</testsuite>

然后简单地从magento文件夹下的控制台运行单元测试
