This bundle provides features that help you run your Symfony-framework-based App's testsuite more efficiently with isolated tests.
It provides a StaticDriver
that will wrap your originally configured Driver
class (like DBAL\Driver\PDOMysql\Driver
) and keeps a database connection statically in the current php process.
With the help of a PHPUnit extension class it will begin a transaction before every testcase and roll it back again after the test finished for all configured DBAL connections. This results in a performance boost as there is no need to rebuild the schema, import a backup SQL dump or re-insert fixtures before every testcase. As long as you avoid issuing DDL queries that might result in implicit transaction commits (Like ALTER TABLE
, DROP TABLE
etc; see https://wiki.postgresql.org/wiki/Transactional_DDL_in_PostgreSQL:_A_Competitive_Analysis) your tests will be isolated and all see the same database state.
It also includes a Psr6StaticArrayCache
that will be automatically configured as meta data & query cache for all EntityManagers. This improved the speed and memory usage for my testsuites dramatically! This is especially beneficial if you have a lot of tests that boot kernels (like Controller tests or ContainerAware tests) and use Doctrine entities.
-
install via composer
composer require --dev dama/doctrine-test-bundle
-
Enable the bundle for your test environment in your
AppKernel.php
if (in_array($env, ['dev', 'test'])) { ... if ($env === 'test') { $bundles[] = new DAMA\DoctrineTestBundle\DAMADoctrineTestBundle(); } }
Note: if you are using symfony flex and you are allowing contrib recipes (
extra.symfony.allow-contrib=true
) then the bundle will be automatically enabled for the'test'
environment. See https://github.com/symfony/recipes-contrib/tree/master/dama/doctrine-test-bundle
-
Add the Extension to your PHPUnit XML config
-
PHPUnit 8 or 9:
<phpunit> ... <extensions> <extension class="DAMA\DoctrineTestBundle\PHPUnit\PHPUnitExtension" /> </extensions> </phpunit>
-
PHPUnit 10+:
<phpunit> ... <extensions> <bootstrap class="DAMA\DoctrineTestBundle\PHPUnit\PHPUnitExtension" /> </extensions> </phpunit>
-
-
Make sure you also have
phpunit/phpunit
available as adev
dependency (versions 8, 9 and 10 are supported with the built-in extension) to run your tests. Alternatively this bundle is also compatible withsymfony/phpunit-bridge
and itssimple-phpunit
script. (Note: you may need to make sure the phpunit-bridge requires the correct PHPUnit 8+ Version using the environment variableSYMFONY_PHPUNIT_VERSION
). -
That's it! From now on whatever changes you do to the database within each single testcase (be it a
WebTestCase
or aKernelTestCase
or any custom test) are automatically rolled back for you ๐
Enable the extension in your Behat config (e.g. behat.yml
)
default:
# ...
extensions:
DAMA\DoctrineTestBundle\Behat\ServiceContainer\DoctrineExtension: ~
That's it! From now on whatever changes you do to the database within each scenario are automatically rolled back for you.
Please note that this is only works if the tests are executed in the same process as Behat. This means it cannot work when using e.g. Selenium to call your application.
The bundle exposes a configuration that looks like this by default:
dama_doctrine_test:
enable_static_connection: true
enable_static_meta_data_cache: true
enable_static_query_cache: true
Setting enable_static_connection: true
means it will enable it for all configured doctrine dbal connections.
You can selectively only enable it for some connections if required:
dama_doctrine_test:
enable_static_connection:
connection_a: true
An example usage can be seen within the functional tests included in this bundle: https://github.com/dmaicher/doctrine-test-bundle/tree/master/tests
- initial database bootstrap is done using PHPUnit bootstrap file: https://github.com/dmaicher/doctrine-test-bundle/blob/master/tests/bootstrap.php
- several tests that make sure any changes from previous tests are rolled back: https://github.com/dmaicher/doctrine-test-bundle/blob/master/tests/Functional/PhpunitTest.php
This bundle is also used on the official Symfony Demo testsuite: https://github.com/symfony/demo
Sometimes it can be useful to be able to debug the database contents when a test failed. As normally all changes are rolled back automatically you can do this manually:
public function testMyTestCaseThatINeedToDebug()
{
// ... something thats changes the DB state
\DAMA\DoctrineTestBundle\Doctrine\DBAL\StaticDriver::commit();
die;
// now the DB changes are actually persisted and you can debug them
}
In case you are running (maybe without knowing it) queries during your tests that are implicitly committing any open transaction (see https://dev.mysql.com/doc/refman/8.0/en/implicit-commit.html for example) you might see an error like this:
Doctrine\DBAL\Driver\PDOException: SQLSTATE[42000]: Syntax error or access violation: 1305 SAVEPOINT DOCTRINE2_SAVEPOINT_2 does not exist
Currently there is no way for this bundle to work with those queries as they simply cannot be rolled back after the test case finished.
