Symfony / Doctrine UnitTests with SQLite memory DB

I'm still working on PHP unit tests for testing my symfony2 controllers. My test classes are derivations of WebTestCase and the tests are doing GET or POST requests to check if everything works fine.

I want to test all underlying layers, but I don't want to mess up my database with the tests. I don't want to use mock-ups, but an in-memory SQLite db, where I can set up a test scenario to check all modifications.

I found a lot of hints how to do this with doctrine 1.x, but they don't work anymore.

So I want something like this:

class BlahblahTest extends WebTestCase {
    public function testXXXYYY() {
        // 1. Setup a new database with SQLite:memory:
        // 2. create the database and all tables according the entities in my project
        $this->createTestScenario(); // 3.
        $crawler = $this->client->request('GET', '/testpage');  // 4.
        // 5. Lots of checks against the database and / or the $crawler data
    }
}

Any chance to get this work?

I never used in memory sqlite database but for testing i do use a sqlite database that is saved.

For that you should add

# app/config/config_test.yml
doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                driver:   pdo_sqlite
                path:     %kernel.cache_dir%/test.db

To your test config (for me config_test.yml)

You should be able to change this to in memory according to the documentation

http://docs.doctrine-project.org/projects/doctrine- dbal/en/latest/reference/configuration.html#pdo-sqlite

memory (boolean): True if the SQLite database should be in-memory (non-persistent). Mutually exclusive with path. path takes precedence.

So the config should then be

# app/config/config_test.yml
doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                driver:   pdo_sqlite
                memory:   true
