在ZF3应用程序的功能PHPUnit测试中，如何关闭数据库连接并减少它们的数量？
几年前，我已经在StackOverflow上创建了一个非常相似甚至几乎相同的。我得到了非常详细的答案，但并没有解决我的问题。现在，问题变得更大了，我开始第二次尝试解决这个问题。由于代码已更改，我不想更新原始问题。这将是一个太大的更新，答案可能与问题的新版本不匹配。因此，我将其表述为一个新的： 我正在使用在ZF3应用程序的功能PHPUnit测试中，如何关闭数据库连接并减少它们的数量？,phpunit,integration-testing,functional-testing,zend-framework3,database-testing,Phpunit,Integration Testing,Functional Testing,Zend Framework3,Database Testing,几年前，我已经在StackOverflow上创建了一个非常相似甚至几乎相同的。我得到了非常详细的答案，但并没有解决我的问题。现在，问题变得更大了，我开始第二次尝试解决这个问题。由于代码已更改，我不想更新原始问题。这将是一个太大的更新，答案可能与问题的新版本不匹配。因此，我将其表述为一个新的： 我正在使用 zendframework/zend测试3.2.2 phpunit/phpunit6.5.14，以及 phpunit/dbunit3.0.3 大多数测试都是一种控制器测试。测试代码通过使用Z
- zendframework/zend测试
3.2.2 - phpunit/phpunit
，以及6.5.14 - phpunit/dbunit
3.0.3
Zend\test\PHPUnit\Controller\AbstractControllerTestCase#dispatch（…）102显示全局状态，如'max_used_connections'；max\u连接数。）
我试图通过放置逻辑来减少连接的数量，比如$this->dbAdapter->getDriver（）->getConnection（）->disconnect（）或/和$this->entityManager->getConnection（）->close（）到控制器测试的我的超类的tearDown（）
。通过这种方式，我将连接的数量减少了大约90个。但是大部分的连接仍然没有被杀死

因为我们看不到您的控制器、存储库等，所以我们不能说您“有错误”。通常，您应该在setUp
方法上建立数据库测试连接，并在tearDown
方法上销毁它。您不应该为应用程序启动连接。应用程序应在需要时启动该连接。既然你用的是教义，它就是这么做的。为什么在测试之前创建/调用EntityManager
如果只运行一个测试而不是整个测试用例，会发生什么？发生了多少连接？也许你在控制器上犯了个错误？也许在仓库里
这里是我看到的代码
- 我看不到初始化器在哪里使用。你在哪里使用它？我不喜欢那种方法
- 您的
DatabaseConnectionTrait
和AbstractControllerTest
类都有\u构造方法。如果一个类覆盖了trait中定义的方法，那么这个类的方法就起作用了。为什么有这种方法
- 你确定你没有反复做同样的事情吗？
getDatabaseConnection
，getConnection
，$this->getConnection（）->getConnection（）
- 在哪里定义静态
$em
属性
unset
处理反射对象时将其取消设置。我知道这是一种简单快捷的方法，但是你应该考虑自己去做。这将是管理ram的更好方法- 为什么要在
tearDown
方法中使用反射来破坏类的所有属性？破坏连接并让php管理垃圾
- 为什么要用
tearDown
方法销毁数据库？如果您将测试数据正确地提供给phpunit，则不需要它。检查DbUnit
的拆卸操作
我建议您一个接一个地运行测试，而不是整个测试用例并检查连接计数。您还应该使用DbUnit测试您的存储库，以确保它们正常工作。由于存储库负责数据库，可能连接数在它们身上增加。据我所知，每个测试都会实例化entity manager的新实例。你能在所有测试中重复使用它吗？谢谢你的评论！我添加了一个static
变量$em
并替换了行$this->entityManager=$this->getApplicationServiceLocator（）->get（'doctrine.entityManager.orm_default'）AbstractControllerTest
的构造函数中，通过以下方式进行编码：self:：$em=self:：$em？：$this->getApplicationServiceLocator（）->get（'doctrine.entitymanager.orm_default'）$this->entityManager=self:：$em
我还设置了一个调试断点，并检查了self:：$em
是否实际被重用——是的，确实如此。但是这个更改并没有影响DB连接的数量。好的，但是应用程序代码仍然从ServiceLocator中获得一个新的EntityManager实例，我想，您是否也可以在locator中替换它？这就是我评论的目的——事实上，我应该提到（尽管我在一个基于Symfony的项目中这样做，但我不确定zend是否存在干净的方式……如果不是的话——尝试一些黑客方式）））我不确定，我是否正确理解了你。您的意思是跨（HTTP）请求使用相同的EntityManager实例？我认为，这是不可能的，因为ServiceLocator每次在应用程序引导时都会被实例化。好吧，我可以把整个地图藏起来
