Filament::serving and tests

Hey!

Maybe a stupid question, but how to get the code inside

Filament::serving

Filament::serving

running in a Feature test?

For performance reasons, I have some code inside

Filament::serving

Filament::serving

, for example some Macros like:

Field::macro("onlyOnEdit", fn() => $this->hidden(fn($record) => !$record || !$record->exists));

Field::macro("onlyOnEdit", fn() => $this->hidden(fn($record) => !$record || !$record->exists));

When I run now a test, it doesn't find the macro, since the

Filament::serving

Filament::serving

isn't called at all?
