Mutation test failed with artisan command

I am failing with the mutation test due to Artisan::call('migration') command. How I fix this.

Mutation fails on:

1) /builds/api/app/Console/Commands/MigrateAllCommand.php:42    [M] MethodCallRemoval

        if (!empty($systemNames)) {
            foreach ($systemNames as $systemName) {
