Start

# Node with 127.0.0.1:5000
python3 Server.py 5000
# Node with 127.0.0.1:5001
python3 Server.py 5001
# Node with 127.0.0.1:5002
python3 Server.py 5002

Test

Before initiating test, make sure all 3 nodes are running with ports 5000, 5001, and 5002.
The integration test fails for very first time for unknown reason.
Please run the test twice.

python3 -m unittest
