php – 如何在没有任何实体的情况下测试doctrine EventListener

该捆绑包与我的其他捆绑包工作正常,但我想对它进行单元测试并对其进行功能测试.

问题是,为了对AuditLoggerListener函数进行功能测试,我需要至少有两个“假”实体,我可以坚持,更新等.

在这个包中我不知道如何做到这一点,因为我只有一个AuditLog实体,我需要使用两个over实体(仅用于测试).

>第一个实体将是“可审计的”(我必须有一个新的条目
audit_log如果我在此实体上执行持久化,更新或删除).
>第二个将是“不可审计的”(我不能有新的条目
在audit_log表中执行持久化,更新或删除时
这个实体).*
>这两个实体可以与唯一的EntityClass相关,但不能是AuditLog的实例

这就是我看到持续功能测试的方式：

<?php
$animal = new Animal(); //this is a fake Auditable entity
$animal->setName('toto');
$em = new EntityManager(); //actually I will use the container to get this manager
$em->persist($animal);
$em->flush();

//Here we test that I have a new line in audit_log table with the right informations

所以我的问题是我的bundle中没有任何Animal实体,我只需要这个来测试bundle,所以它必须只在测试数据库中创建,而不是在生产环境中创建(当我做app时/ console doctrine：schema：update –force

EDIT_1：在阅读完答案后,将对AuditLoggerListener函数进行单元测试,但我仍想进行功能测试

*是的我知道它们有很多,但它们并不符合我的要求.

感谢您的回答,我希望它能帮助一些人！

EDIT_2：这是代码
服务：

我想测试一下这个监听器的preXXXX函数……
所以,例如,我需要测试当我在假实体上持续存在时(我真的不知道如何模拟),我的audit_log表中有一个新条目…
