README

        
This repository is a sample Django project to help test some issues with channels/uvicorn/gunicorn. It has a single view configured at `/delay//` which will time.sleep for `ms` and return 200.

`load_test.py` takes two arguments, `concurrency` and `requests`. It will hit the `/delay/` endpoint with a sequence of request with random delays between 0 and 1 second. The random generator is seeded with 0 before each run, so subsequent runs test the same thing. It prints some statistics on the request results.

# Install dependencies

Install the required dependencies with:

```

python3 -mvenv env

env/bin/pip install --upgrade pip setuptools

env/bin/pip install "django<3" channels uvicorn gunicorn requests

```

# Test scenarios

## 1. Channels returns 500s when workers > 1

Start the server:

```

make asgi

```

Hit the server with 10 requests and concurrency 10:

```

env/bin/python load_test.py 10 10

```

Observe a bunch of errors in your web server log output.

Now run ten requests with concurrency 1:

```

env/bin/python load.test 1 10

```

And see that all is well.
