Development
cunīcu is written almost completely in Go and heavily relies on awesome tooling and packages for Golang:
- GoReleaser for release automation
- Ginkgo and Gomega for testing
- Pion for its ICE, STUN, TURN implementation
- Gont for end-to-end testing in various network topologies
Furthermore use the following services to manage our development:
Testing
We aim to maintain a test coverage above 80% of the lines of code. Please make sure that your merge requests include tests which do not lower the coverage percentage.
cunīcu's code-base is tested using the Ginkgo / Gomega testing framework.
Unit tests can be found alongside the code in files with a _test.go suffix.
End-to-end (e2e) integration tests can be found in the test/e2e directory.
The e2e tests use Gont to construct virtual network environment using Linux's net namespaces and veth point-to-point links.
This allows us to test cunīcu in both simple and complex network topologies including, L2 switches, L3 routers, firewalls and NAT boxes.
Nix
We provide a Nix flake for cunīcu and most related Git repositories to quickly jump into a reproducable development shell by running:
nix develop ./nix
In this shell all required build-time dependencies and tools for cunīcu are available.
I also recommend to setup direnv to automatically enter a development shell whenever you are residing inside the repos directory structure:
echo "use flake ./nix --impure" > .envrc
Website
Please run the following commands to start a development server for the website:
# Ideally you use the Nix flake here to get a working Yarn/NodeJS setup
cd website
yarn start
echo "Test"
