Answer 1

You have to put the DATABASE_URL into your phpunit.xml file, e.g. like this:

<php>
        <ini name="error_reporting" value="-1" />
        <env name="KERNEL_CLASS" value="App\Kernel" />
        <env name="APP_ENV" value="test" />

        <!-- ###+ doctrine/doctrine-bundle ### -->
        <!-- Format described at http://docs.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/configuration.html#connecting-using-a-url -->
        <!-- For an SQLite database, use: "sqlite:///%kernel.project_dir%/var/data.db" -->
        <!-- Configure your db driver and server_version in config/packages/doctrine.yaml -->
        <env name="DATABASE_URL" value="mysql://root@127.0.0.1:3306/symfony4-database"/>
        <!-- ###- doctrine/doctrine-bundle ### -->
    </php>
