reddit-experiments 1.0.3a0

reddit's python experiments framework

experiments.py

Experiments allow us to determine the impact of changes we make. This library helps you run and track them in Baseplate.py services.

Documentation: https://reddit-experiments.readthedocs.io/

Usage

Install the library:

$ pip install reddit-experiments

Add the client to your application's Baseplate context:

baseplate.configure_context(
  {
     ...
     "experiments": ExperimentsClient(event_logger),
     ...
  }
)

and use it in request:

def my_method(request):
   if request.experiments.variant("foo") == "bar":
       pass

See the documentation for more information.

Development

A Dockerfile is provided to get a development environment running. To use it, build the base Docker image:

$ docker build -t experiments .

And then fire up the environment and use the provided Makefile targets to do common tasks:

$ docker run -it -v $PWD:/src -w /src experiments
$ make fmt

The following make targets are provided:

• fmt: Apply automatic formatting to the source code.
• lint: Run linters on the code.
• test: Run the test suite.
• docs: Build the docs. Output can be found in build/html/.

Note: some tests are skipped by default locally because they are quite slow. Enable these by setting CI=true in the environment: CI=true make test.
