Database Tests

If you plan on loading fixtures with your tests, make sure you have the DoctrineFixturesBundle installed and configured first: Doctrine Fixtures setup and configuration instructions

In case tests require database access make sure that the database is created and proxies are generated. For tests that rely on specific database contents, write fixture classes and call loadFixtures() method. This will replace the database configured in config_test.yml with the specified fixtures. Please note that loadFixtures() will delete the contents from the database before loading the fixtures. That's why you should use a designated database for tests.

Usage

You'll have to make the following changes in order to use that bundle:

+use Liip\TestFixturesBundle\Services\DatabaseToolCollection;
+use Liip\TestFixturesBundle\Services\DatabaseTools\AbstractDatabaseTool;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class MyControllerTest extends WebTestCase
{
+    /** @var AbstractDatabaseTool */
+    protected $databaseTool;

    public function setUp(): void
    {
        parent::setUp();

+        $this->databaseTool = self::$container->get(DatabaseToolCollection::class)->get();
    }

    public function testIndex()
    {
        // If you need a client, you must create it before loading fixtures because
        // creating the client boots the kernel, which is used by loadFixtures
        $client = $this->createClient();

+        // add all your fixtures classes that implement
+        // Doctrine\Common\DataFixtures\FixtureInterface
+        $this->databaseTool->loadFixtures([
+            'Bamarni\MainBundle\DataFixtures\ORM\LoadData',
+            'Me\MyBundle\DataFixtures\ORM\LoadData'
+        ]);

        // you can now run your functional tests with a populated database
        // ...
    }
}

Methods

self::$container->get(DatabaseToolCollection::class) has a method get() to load the default service, it also accepts several arguments:

name of the object manager
name of the registry, doctrine is the default value
purge mode with true or false

$this->databaseTool gives access to 3 methods to load fixtures:

loadFixtures(), the first parameter accepts an array of fixtures, the second argument is optional too and has to be set to true in order to append the fixtures to the existing data
loadAliceFixture(), the first parameter accepts an array of Alice fixtures, the second argument is optional too and has to be set to true in order to append the fixtures to the existing data
loadAllFixtures(), it accepts an array of groups, see load all fixtures

It also give access to other helpers:

setDatabaseCacheEnabled() accept true or false to disable the cache
- you can call $this->databaseTool->withDatabaseCacheEnabled(false)->loadFixtures(…) to disable the cache on-demand
setPurgeMode() accept true or false to disable purging the database
- you can call $this->databaseTool->withPurgeMode(false)->loadFixtures(…) to disable the purging on-demand
setExcludedDoctrineTables() accepts an array of table names that will be preserved, see Exclude some tables

Tips for Fixture Loading Tests

SQLite (↑)

If you want your tests to run against a completely isolated database (which is recommended for most functional-tests), you can configure your test-environment to use a SQLite-database. This will make your tests run faster and will create a fresh, predictable database for every test you run.
- For symfony 4 : create file if it doesn't exists config/packages/test/doctrine.yaml, and if it does append those lines:
```
# config/packages/test/doctrine.yaml
doctrine:
    dbal:
        driver: pdo_sqlite
        path: "%kernel.cache_dir%/test.db"
        url: null
```
NB: If you have an existing Doctrine configuration which uses slaves be sure to separate out the configuration for the slaves. Further detail is provided at the bottom of this README.
In order to run your tests even faster, use LiipFunctionalBundle cached database. This will create backups of the initial databases (with all fixtures loaded) and re-load them when required.

Attention: you need Doctrine >= 2.2 to use this feature.
```
# sf4: config/packages/test/framework.yaml
liip_test_fixtures:
    cache_db:
        sqlite: 'Liip\TestFixturesBundle\Services\DatabaseBackup\SqliteDatabaseBackup'
```

Custom database cache services (↑)

To create custom database cache service:

Create cache class, implement \Liip\TestFixturesBundle\Services\DatabaseBackup\DatabaseBackupInterface and add it to config

For example:

# app/config/config_test.yml
liip_test_fixtures:
    cache_db:
        mysql: 'Liip\TestFixturesBundle\Services\DatabaseBackup\MysqlDatabaseBackup'
        mongodb: 'Liip\TestFixturesBundle\Services\DatabaseBackup\MongodbDatabaseBackup'
        phpcr: ...
        db2: ...
        [Other \Doctrine\DBAL\Platforms\AbstractPlatform name]: ...

Attention: Liip\TestFixturesBundle\Services\DatabaseBackup\MysqlDatabaseBackup requires mysql-client installed on server.

Attention: Liip\TestFixturesBundle\Services\DatabaseBackup\MongodbDatabaseBackup requires mongodb-clients installed on server.

Load fixtures (↑)

Load your Doctrine fixtures in your tests:

use Liip\TestFixturesBundle\Services\DatabaseToolCollection;
use Liip\TestFixturesBundle\Services\DatabaseTools\AbstractDatabaseTool;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class MyControllerTest extends WebTestCase
{
    /**
     * @var AbstractDatabaseTool
     */
    protected $databaseTool;

    public function setUp(): void
    {
        parent::setUp();

        $this->databaseTool = self::$container->get(DatabaseToolCollection::class)->get();
    }

    public function testIndex()
    {
        // If you need a client, you must create it before loading fixtures because
        // creating the client boots the kernel, which is used by loadFixtures
        $client = $this->createClient();

        // add all your fixtures classes that implement
        // Doctrine\Common\DataFixtures\FixtureInterface
        $this->databaseTool->loadFixtures([
            'Bamarni\MainBundle\DataFixtures\ORM\LoadData',
            'Me\MyBundle\DataFixtures\ORM\LoadData'
        ]);

        // you can now run your functional tests with a populated database
        // ...
    }
}

Have an empty database without fixtures (↑)

If you don't need any fixtures to be loaded and just want to start off with an empty database (initialized with your schema), you can simply call loadFixtures without any argument.

$this->databaseTool->loadFixtures();
}

Exclude some tables (↑)

Given that you want to exclude some of your doctrine tables from being purged when loading the fixtures, you can do so by passing an array of tablenames to the setExcludedDoctrineTables method before loading the fixtures.

$this->databaseTool->setExcludedDoctrineTables(['my_tablename_not_to_be_purged']);
$this->databaseTool->loadFixtures([

Append data (↑)

If you want to append fixtures instead of clean database and load them, you have to consider use the second parameter $append with value true.

$this->databaseTool->loadFixtures([
    'Me\MyBundle\DataFixtures\ORM\LoadAnotherObjectData',
], true);

Other drivers (↑)

This bundle uses Doctrine ORM by default. If you are using another driver just specify the service id of the registry manager:

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class MyControllerTest extends WebTestCase
{
    // …

   
    public function setUp(): void
    {
        // …

        $this->databaseTool = self::$container->get(DatabaseToolCollection::class)->get('default', 'doctrine_phpcr');
    }
}

Load all fixtures (↑)

If you need to load all fixtures, you can call loadAllFixtures. With the optional argument groups, only those fixtures belonging to a group (i.e. using the FixtureGroupInterface) are loaded, like when calling the command doctrine:fixtures:load --group=...:

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class MyControllerTest extends WebTestCase
{
    // …

   public function testIndex()
   {
       // If you need a client, you must create it before loading fixtures because
       // creating the client boots the kernel, which is used by loadFixtures
       $client = $this->createClient();
       $this->databaseTool->loadAllFixtures(['mygroup1', 'mygroup2']);

       // you can now run your functional tests with a populated database
       // ...
   }
}

Loading Fixtures Using Alice (↑)

If you would like to setup your fixtures with yml files using Alice, there is an helper function loadFixtureFiles which takes an array of resources, or paths to yml files, and returns an array of objects. This method uses the Theofidry AliceDataFixtures loader rather than the FunctionalTestBundle's load methods. You should be aware that there are some difference between the ways these two libraries handle loading.

$fixtures = $this->databaseTool->loadAliceFixture([
    '@AcmeBundle/DataFixtures/ORM/ObjectData.yml',
    '@AcmeBundle/DataFixtures/ORM/AnotherObjectData.yml',
    __DIR__.'/../../DataFixtures/ORM/YetAnotherObjectData.yml',
]);

If you want to clear tables you have the following two ways:

Only to remove records of tables;
Truncate tables.

The first way is consisted in using the second parameter $append with value false. It allows you only to remove all records of table. Values of auto increment won't be reset.

$fixtures = $this->databaseTool->loadAliceFixture([
        '@AcmeBundle/DataFixtures/ORM/ObjectData.yml',
        '@AcmeBundle/DataFixtures/ORM/AnotherObjectData.yml',
        __DIR__.'/../../DataFixtures/ORM/YetAnotherObjectData.yml',
    ],
    false
);

The second way is consisted in using the second parameter $append with value false and the last parameter $purgeMode with value Doctrine\Common\DataFixtures\Purger\ORMPurger::PURGE_MODE_TRUNCATE. It allows you to remove all records of tables with resetting value of auto increment.

<?php

use Doctrine\Common\DataFixtures\Purger\ORMPurger;

$files = [
     '@AcmeBundle/DataFixtures/ORM/ObjectData.yml',
     '@AcmeBundle/DataFixtures/ORM/AnotherObjectData.yml',
     __DIR__.'/../../DataFixtures/ORM/YetAnotherObjectData.yml',
 ];
$fixtures = $this->databaseTool->loadAliceFixture($files, false, null, 'doctrine', ORMPurger::PURGE_MODE_TRUNCATE );

Non-SQLite (↑)

The Bundle will not automatically create your schema for you unless you use SQLite or use doctrine/orm < 2.6.

So you have several options:

use SQLite driver in tests
upgrade doctrine/orm :
```
composer require doctrine/orm:^2.6
```
if you prefer to use another database but want your schema/fixtures loaded automatically, you'll need to do that yourself. For example, you could write a setUp() function in your test, like so:

use Doctrine\ORM\Tools\SchemaTool;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class AccountControllerTest extends WebTestCase
{
    public function setUp()
    {
        $em = $this->getContainer()->get('doctrine')->getManager();
        if (!isset($metadatas)) {
            $metadatas = $em->getMetadataFactory()->getAllMetadata();
        }
        $schemaTool = new SchemaTool($em);
        $schemaTool->dropDatabase();
        if (!empty($metadatas)) {
            $schemaTool->createSchema($metadatas);
        }

        $fixtures = [
            'Acme\MyBundle\DataFixtures\ORM\LoadUserData',
        ];
        $this->databaseTool->loadFixtures($fixtures);
    }
//...
}

Without something like this in place, you'll have to load the schema into your test database manually, for your tests to pass.

Referencing fixtures in tests (↑)

In some cases you need to know for example the row ID of an object in order to write a functional test for it, e.g. $crawler = $client->request('GET', "/profiles/$accountId"); but since the $accountId keeps changing each test run, you need to figure out its current value. Instead of going via the entity manager repository and querying for the entity, you can use setReference()/getReference() from the fixture executor directly, as such:

In your fixtures class:

...
class LoadMemberAccounts extends AbstractFixture 
{
    public function load() 
    {
        $account1 = new MemberAccount();
        $account1->setName('Alpha');
        $this->setReference('account-alpha', $account1);
        ...

and then in the test case setup:

...
    public function setUp()
    {
        $this->fixtures = $this->databaseTool->loadFixtures([
            'AppBundle\Tests\Fixtures\LoadMemberAccounts'
        ])->getReferenceRepository();
    ...

and finally, in the test:

        $accountId = $this->fixtures->getReference('account-alpha')->getId();
        $crawler = $client->request('GET', "/profiles/$accountId");

Doctrine Slaves and SQLite (↑)

If your main configuration for Doctrine uses Slaves, you need to ensure that the configuration for your SQLite test environment does not include the slave configuration.

The following error can occur in the case where a Doctrine Slave configuration is included:

SQLSTATE[HY000]: General error: 1 no such table NameOfTheTable

This may also manifest itself in the command doctrine:create:schema doing nothing.

To resolve the issue, it is recommended to configure your Doctrine slaves specifically for the environments that require them.
