KeyError: 'RUNNEL_TESTING'

[ColCh]

Running simple example for middlewares:

from datetime import datetime

from runnel import App, Record, Events, Middleware

app = App(name="myapp", redis_url="redis://127.0.0.1")


class Order(Record):
    order_id: int
    created_at: datetime
    amount: int


class Printer(Middleware):
    async def handler(self, parent: Events, **kwargs):
        async for x in parent:
            print(x)
            yield x


orders = app.stream("orders", record=Order, partition_by="order_id")


@app.processor(orders, middleware=[Printer()])
async def printer(events: Events):
    async for order in events.records():
        pass

KeyError: 'RUNNEL_TESTING'

Exporting env variable RUNNEL_TESTING fixes this, indeed. But I suppose, os.environ["RUNNEL_TESTING"] should be os.environ.get("RUNNEL_TESTING"), right?

In my opnion, It's better to use "os.getevn" rather than "os.environ".
