A program to send and receive messages based on ZMQ and Protobuf (see orwell-int/messages).

Python 2.7 zmq protobuf (v2) make

Get and install dependencies and create virtual environment.

make develop

Test with simple scenario that things work.

make start

Test with unittests that things work.

make test

To launch a scenario of your own you need to activate the virtual environment and call it directly. The following example works as standalone.

source env/bin/activate
python orwell/shooter/main.py Standalone.yml -d 1

The format can mostly be deduced from the examples. Each scenario file is a YAML file. The main three sections are

• messages: you may describe you messages in advance here
• sockets: you may put the different sockets needed for communications (two for each thread: in/out)
• threads: each thread can be seen as a small program that will send and receive messages as expect and perform some more actions

Actions available:

• In: receive a message (messages of the wrong type are discarded)
• Out: send a message
• Equal: assert values are identical
• Absent: asssert that a value is absent for a collection
• Sleep: sleep for some time in seconds
• UserInput: wait for user input
