Laravel multiple databases PHPUnit [duplicate]

Question

I am developing a application with multiple database access and I want to have PHPUnit tests with this. My current approache is to have in the config\databases.php multiple connections (mysql, mysql2, mysql3) so I can have in the env file a different access for all of them. Because of this, the models have the $connection variable defined. In my first feature test I want to access a page and just see the data that I am providing in my factory, so just to get things started. In my phpunit.xml file I have specified the DB_CONNECTION to be sqlite and for each of the MySql setting to have the value=":memory:".

LATER EDIT

<php>
    <env name="APP_ENV" value="testing"/>
    <env name="CACHE_DRIVER" value="array"/>
    <env name="SESSION_DRIVER" value="array"/>
    <env name="QUEUE_DRIVER" value="sync"/>
    <env name="DB_CONNECTION" value="sqlite"/>
    <env name="DB_DATABASE_1" value=":memory:"/>
    <env name="DB_DATABASE_2" value=":memory:"/>
    <env name="DB_DATABASE_3" value=":memory:"/>
</php>

So above you can find the relevant code from PHPUnit.

.env

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=db1
DB_USERNAME=xxx
DB_PASSWORD=xxx

DB_HOST_2=127.0.0.1
DB_PORT_2=3306
DB_DATABASE_2=db2
DB_USERNAME_2=xxx
DB_PASSWORD_2=xxx

DB_HOST_2=127.0.0.1
DB_PORT_2=3306
DB_DATABASE_3=db3
DB_USERNAME_3=xxx
DB_PASSWORD_3=xxx

The problem that I have is the fact that when I run the tests, i have this error -> PDOException: SQLSTATE[HY000] [1049] Unknown database ':memory:'.

So somehow Laravel is not parsing the memory value. Any suggestion will be mush appreciated. Thank you

I was having the same issue, but I got things working with some help from Adam Wathan on Twitter.

Here's what I did:

phpunit.xml:

<env name="DB_CONNECTION" value="sqlite"/>
<env name="DB_DATABASE" value=":memory:"/>
<env name="DB_CONNECTION_ACTIVITY_LOG" value="sqlite"/>
<env name="DB_DATABASE_ACTIVITY_LOG" value=":memory:"/>

config/database.php:

'sqlite' => [
    'driver' => 'sqlite',
    'database' => env('DB_DATABASE', database_path('database.sqlite')),
    'prefix' => '',
],

'mysql' => [
    'driver' => env('DB_CONNECTION', 'mysql'),
    'host' => env('DB_HOST', '127.0.0.1'),
    'port' => env('DB_PORT', '3306'),
    'database' => env('DB_DATABASE', 'forge'),
    'username' => env('DB_USERNAME', 'forge'),
    'password' => env('DB_PASSWORD', ''),
    'unix_socket' => env('DB_SOCKET', ''),
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
    'prefix' => '',
    'strict' => true,
    'engine' => null,
],

'mysql-activity-log' => [
    'driver' => env('DB_CONNECTION_ACTIVITY_LOG', 'mysql'),
    'host' => env('DB_HOST_ACTIVITY_LOG', '127.0.0.1'),
    'port' => env('DB_PORT_ACTIVITY_LOG', '3306'),
    'database' => env('DB_DATABASE_ACTIVITY_LOG', 'forge'),
    'username' => env('DB_USERNAME_ACTIVITY_LOG', 'forge'),
    'password' => env('DB_PASSWORD_ACTIVITY_LOG', ''),
    'unix_socket' => env('DB_SOCKET_ACTIVITY_LOG', ''),
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
    'prefix' => '',
    'strict' => true,
    'engine' => null,
],

.env:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=my-app
DB_USERNAME=root
DB_PASSWORD=

DB_CONNECTION_ACTIVITY_LOG=mysql-activity-log
DB_HOST_ACTIVITY_LOG=127.0.0.1
DB_PORT_ACTIVITY_LOG=3306
DB_DATABASE_ACTIVITY_LOG=my-app
DB_USERNAME_ACTIVITY_LOG=root
DB_PASSWORD_ACTIVITY_LOG=

Also, for anyone not up to the point of the PDOException, make sure to set the connections in your migrations/models, too.

database/migrations/my_migration.php:

Schema::connection(env('DB_CONNECTION_ACTIVITY_LOG', 'mysql'))->create(...);

app/MyModel.php:

class MyModel extends Model
{
    public function __construct($attributes = [])
    {
        parent::__construct($attributes);
        $this->connection = config('app.env') === 'testing' ? 'sqlite' : 'mysql-activity-log';
    }
    ...
}
