Is it possible to make Symfony + gRPC + Codeception friends?

Question

PHP

Codeception, in order to build the Kernel symphony, you need the appropriate module:

modules:
    enabled:
        -   Symfony:
                app_path: 'src'
                environment: 'test'

And at the same time, it is worth putting
composer require codeception/module-symfony --dev

Without changing anything else at all, tests (even one banal test assertTrue (true)) fall with an error:

Expected to find class "App\Grpc\..." in file "/var/www/..." while importing services from resource "../src/*", but it was not found! Check the namespace prefix used with the resource in /var/www/.../services.yaml (which is being imported from "/var/www/.../src/Kernel.php")

At the same time, if you remove the classes associated with gRPC from src / Grpc, then everything works right away.

PS Yes, I know that PHP cannot act as a client for gRPC, I'm interested in the question - somehow you can use Symfony + gRPC + Codeception in one bundle, or Codeception will have to be abandoned, and somehow get by with pure PHPUnit and mocks on all calls to gRPC classes.
