使用 Symfony 测试数据库插入 [英] Testing database insert using Symfony
问题描述
大家好，
在过去的几天里，我一直在研究测试驱动开发，并决定我也需要学习它.虽然我无法弄清楚如何精确地做到这一点.
I have been looking into Test Driven Development a lot in the past few days and decided that I need to learn it as well. Although I can not figure out how to do it precisely.
我的项目依赖于 Symfony2.1.6 框架和 Doctrine，所以我有一些需要填充的数据库表.
My project depends on the Symfony2.1.6 framework and Doctrine so I have some Database-tables that needs filling.
书籍 (1,n) - (0,n) 类型
Book (1,n) - (0,n) Genre
现在，如果我想插入流派记录，我首先需要编写一个测试以确保所有内容都按应有的方式插入(或者我错了吗?)
Now if I want to insert a Genre-record I first need to write a test to ensure everything is being inserted as it should (or am I wrong?)
现在的问题是我不知道如何访问我的数据库，因为它是由框架管理的.
The problem now is that I dont know how to access my Database as it is managed by the framework.
我唯一能找到的是 LiipFunctionalTestBundlehttps://github.com/liip/LiipFunctionalTestBundle 每次运行测试时都会创建和恢复一个临时数据库.我已经按照说明设置了所有内容.
The only thing I could find was with the LiipFunctionalTestBundle https://github.com/liip/LiipFunctionalTestBundle which creates and restores a temporary database everytime I run a test. I have setup everything according to the Instructions.
我的 app/config/config_test.yml 现在看起来像这样:
My app/config/config_test.yml looks like this now:
imports:
- { resource: config_dev.yml }
framework:
test: ~
session:
storage_id: session.storage.filesystem
liip_functional_test: ~
web_profiler:
toolbar: false
intercept_redirects: false
swiftmailer:
disable_delivery: true
liip_functional_test:
cache_sqlite_db: true
doctrine:
dbal:
default_connection: default
connections:
default:
driver: pdo_sqlite
path: %kernel.cache_dir%/test.db
所以现在我有一个 GenreTest 类:
Liip 没有文档，所以我只是尝试了这样的方法.
So now I have a GenreTest class:
Liip doesn't have documentation so I just tried an approach like this.
use LiipFunctionalTestBundleTestWebTestCase;
class GenreTest extends WebTestCase {
public function testInsert() {
$container = $this->getContainer();
$registry = $container->get('doctrine');
$em = $registry->getEntityManager(null);
$genre = new Genre();
$genre->setName("testGenre");
$em->persist($genre);
$em->flush();
$result = $em->createQuery("SELECT g FROM QkprodMangressBundle:Genre g ".
"WHERE g.name = :name")
->setParameter("name", $genre->getName())
->getResult();
$this->assertEqual($result[0]->getName(), $genre->getName());
}
}

我遇到的最大问题是.. 我该如何测试这样的东西?或者我什至测试数据库通信?伪造数据库通过自定义实现进行通信似乎不像对我来说是个好主意，因为它将在生产中使用 ORM 和 Doctrine环境也好.
The big question I am having is.. how do I test something like that? Or do I even test database communication? Faking the database communication through a custom implementation doesn't seem like a good idea to me because it will use ORM and Doctrine in the production environment as well.
对不起..这里原来是一本小小说.
Sorry.. turned out to be a little novel here.
推荐答案
我几乎完全通过以下方式解决了我的问题:
I have, almost completely, solved my problem by:
安装 db-communication 所需的驱动程序 ;)
PDO_SQLITE 驱动程序不存在.. 怎么办?
sudo apt-get install php5-sqlite
在每次测试运行时重新创建模式

<小时>这是我对数据库的班级测试
namespace QkprodMangressBundleEntity;
use QkprodMangressBundleEntityGenre;
use SymfonyBundleFrameworkBundleTestWebTestCase;
private $em;
/**
* Sets up environment for testing
* Regenerates Database schema before every test-run
*/
public function setUp() {
static::$kernel = static::createKernel();
static::$kernel -> boot();
$this -> em = static::$kernel->getContainer()
->get('doctrine')
->getEntityManager();
$this->regenerateSchema();
}
protected function tearDown() {
parent::tearDown();
$this -> em -> close();
}
/**
* Drops current schema and creates a brand new one
*/
protected function regenerateSchema() {
$metadatas = $this->em->getMetadataFactory()->getAllMetadata();
if (!empty($metadatas)) {
$tool = new DoctrineORMToolsSchemaTool($this->em);
$tool -> dropSchema($metadatas);
$tool -> createSchema($metadatas);
}
}
public function testInsert() {
$genre = new Genre();
$genre -> setName("testGenre");
$this -> em -> persist($genre);
$this -> em -> flush();
$result = $this -> em
-> createQuery("SELECT g "
. " FROM QkprodMangressBundle:Genre g "
. " WHERE g.name = :name")
-> setParameter("name", $genre -> getName())
-> getResult();
$this -> assertEquals($result[0] -> getName(), $genre -> getName());
}
}
无法让 LiipBundle 工作，但您可以通过设置 symfony 将 sqlite db 保存在内存而不是文件系统中来提高速度.https://stackoverflow.com/a/10460139/1177024
# app/config/config_test
doctrine:
dbal:
driver: pdo_sqlite
path: :memory:
memory: true
或者可能只创建一次架构，而不是重新创建它，只需使用新备份覆盖数据库即可.
Or maybe only create the schema once and instead of recreating it, just override the database with a fresh backup.
我希望这可以缩短一些有同样问题的人的搜索时间！感谢一路上帮助我的每一个人:)你太棒了！
I hope this shortens the search for some people having the same problem! Thanks to everyone helping me along the way :) You are great!
