symfony 5 中的功能测试

Question

这是我的 symfony 项目，我正在其中练习功能测试，当我测试我的功能时出现这样的错误。

在这里，发生我的错误的代码部分：\

<?php

namespace App\Tests;

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use App\Entity\Category;

class AdminControllerCategoriesTest extends WebTestCase
{
public function setUp():void
{
    parent::setUp();
    $this->client = static::createClient();

    $this->entityManager = $this->client->getContainer()->get('doctrine.orm.entity_manager');

    $this->entityManager->beginTransaction();

    $this->entityManager->getConnection()->setAutoCommit(false);
}

public function tearDown():void
{
    parent::tearDown();
    $this->entityManager->rollback();
    $this->entityManager->close();
    $this->entityManager = null; //avoid memory leaks
}

public function testTextOnPage()
{
    $crawler = $this->client->request('GET', '/admin/categories');
    $this->assertSame('Categories list', $crawler->filter('h2')->text());
    $this->assertContains('Electronics', $this->client->getResponse()->getContent());
}

public function testNumberOfItems()
{
    $crawler = $this->client->request('GET', '/admin/categories');
    $this->assertCount(21, $crawler->filter('option'));
}
}

在这里，我的 .env，我有数据库连接：

    # In all environments, the following files are loaded if they exist,
# the latter taking precedence over the former:
#
#  * .env                contains default values for the environment variables needed by the app
#  * .env.local          uncommitted file with local overrides
#  * .env.$APP_ENV       committed environment-specific defaults
#  * .env.$APP_ENV.local uncommitted environment-specific overrides
#
# Real environment variables win over .env files.
#
# DO NOT DEFINE PRODUCTION SECRETS IN THIS FILE NOR IN ANY OTHER COMMITTED FILES.
#
# Run "composer dump-env prod" to compile .env files for production use (requires symfony/flex >=1.2).
# https://symfony.com/doc/current/best_practices.html#use-environment-variables-for-infrastructure-configuration

###> symfony/framework-bundle ###
APP_ENV=dev
APP_SECRET=018d7408d23791c60854cbb4fc65b667
###< symfony/framework-bundle ###

###> doctrine/doctrine-bundle ###
# Format described at https://www.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/configuration.html#connecting-using-a-url
# IMPORTANT: You MUST configure your server version, either here or in config/packages/doctrine.yaml
#
# DATABASE_URL="sqlite:///%kernel.project_dir%/var/data.db"
DATABASE_URL="mysql://root:@127.0.0.1:3306/symf5?serverVersion=mariadb-10.4.11"
# DATABASE_URL="postgresql://symfony:ChangeMe@127.0.0.1:5432/app?serverVersion=13&charset=utf8"
###< doctrine/doctrine-bundle ###

在这里，我的 .env.test 文件中有以下代码：

    # define your env variables for the test env here
KERNEL_CLASS='App\Kernel'
APP_SECRET='$ecretf0rt3st'
SYMFONY_DEPRECATIONS_HELPER=999999
PANTHER_APP_ENV=panther
PANTHER_ERROR_SCREENSHOT_DIR=./var/error-screenshots

我不知道出了什么问题，我尝试了不同的方法，但它不起作用，我也不知道这有什么问题以及该怎么做。希望你们能帮助我解决我的问题。谢谢你！

Answer 1

你有两个选择：

1. 为您的测试创建新数据库
2. 删除数据库测试中的dbname_suffix，该测试负责为新数据库测试提供后缀名称 -at config/packages/test/doctrine.yaml -

when@test:
    doctrine:
        dbal:
            # "TEST_TOKEN" is typically set by ParaTest
            dbname_suffix: '_test%env(default::TEST_TOKEN)%'

Answer 2

我认为您可能忘记创建 .env.test 文件。

在文档中，您可以阅读需要此文件：

https://symfony.com/doc/current/testing.html#customizing-environment-variables

在此文件中，您将使用正确的数据库进行测试。

告诉我它是否有效！
