Injection Container Resetting For Tests Example

This is an example of how one can use the testing utility function reset_injection_container to clear all state from the injection container including all registered injectables and namespaces.

injection_container_resetting_example.py

from examples import Example
from injectable import (
    injectable,
    autowired,
    Autowired,
    load_injection_container,
)
from injectable.errors import InjectionError
from injectable.testing import reset_injection_container


@injectable
class Foo:
    def do_something(self):
        print("doing something")


class InjectionContainerResetting(Example):
    def run(self):
        self.bar()
        # doing something

        reset_injection_container()

        try:
            self.bar()
            # WARNING:root:Injection Container is empty. Make sure \
            # 'load_injection_container' is being called before any injections are made.
        except InjectionError as e:
            print(e)
            # No injectable matches class 'Foo'

    @autowired
    def bar(self, foo: Autowired(Foo)):
        foo.do_something()
