Support for multiple profiles in egg

[pawojciechowski]

Lets assume such a situation

from abc import ABC, abstractmethod
from haps import base, egg, Container as IoC, PROFILES
from haps.config import Configuration

@base
class IMailService(ABC):
    @abstractmethod
    def send_mail(self, text: str, to: str, **kwargs):
        pass

@egg
class MailService(IMailService):
    def send_mail(self, text: str, to: str, **kwargs):
        # Send mail here
        pass

@egg(profile='mail_disabled')
class DummyMailService(IMailService):
    def send_mail(self, text: str, to: str, **kwargs):
        pass


profiles = ['mail_disabled']

Configuration().set(PROFILES, profiles)
IoC.autodiscover(['app'])

Case

When it comes to testing I need to configure test profiles like this:

profiles = ['mail_disabled']

Configuration().set(PROFILES, profiles)
IoC.autodiscover(['app'])

Assume I have more than one service like MailService with Dummy implementation, then the configuration will look like this:

profiles = ['mail_disabled', 'serviceX_disabled', 'serviceY_disabled', ...]

Configuration().set(PROFILES, profiles)
IoC.autodiscover(['app'])

It's a lot of profiles and we need to update base tests configuration every time we add a new service...

Solution

We can make it a lot easier with defining multiple profiles on eggs like

...

@egg(profiles=['mail_disabled', 'test'])
class DummyMailService(IMailService):
    def send_mail(self, text: str, to: str, **kwargs):
        pass

Then our testing configuration will be simply:

profiles = ['test']

Configuration().set(PROFILES, profiles)
IoC.autodiscover(['app'])
