Question

出于集成测试的目的，我试图创建一个用于测试环境的sqlite数据库，但是当我运行php bin/console doctrine:schema:create --env=test时，我得到表已经存在的错误。我猜想是因为它并不是真正在创建新的测试数据库，而是在现有数据库上进行。

好像没有从env.test中读取。

我在config / test中创建了一个doctrine.yaml，如下所示：

doctrine:
dbal:
    driver: 'pdo_sqlite'
    url: 'sqlite:///%kernel.project_dir%/var/data/test.sqlite'

创建sqlite测试数据库缺少什么？

我遇到错误的奇怪事情：

In PDOConnection.php line 90:

 SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'user_menu' already exists

为什么要使用SQL？不应该将它用于sqlite，对吗？

在config / packages / doctrine.yaml中，我有：

parameters:
# Adds a fallback DATABASE_URL if the env var is not set.
# This allows you to run cache:warmup even if your
# environment variables are not available yet.
# You should not need to change this value.
env(DATABASE_URL): ''

此问题是由Symfony合并配置文件的方式引起的。

/config/packages/*.yml> /config/packages/<env>/*.yml

这导致将packages/doctrine.yml中定义的所有连接和实体管理器添加到您的packages/test/doctrine.yml

要查看Symfony将使用的合并配置设置，请运行：

php bin/console --env=test debug:config doctrine

由于运行bin/console --env=test doctrine:schema:create，将尝试为结果配置中存在的实体管理器的所有 ALL 创建架构。

要解决此问题，您需要将环境配置分为prod，test和dev，或者使用.env.test更改Syfmony使用的URL。

取决于您需要访问实体经理的方式
