tinycr-1's Introduction

TinyCR

Running Tests

Running tests requires docker

docker-compose up --scale client=5

Testing out the system interactively

Running interactively with multiple clients requires docker

docker-compose up --scale test-framework=0 client=5
docker-compose logs

Running with single client can be done without docker
