# Development and testing Use Rust 1.92 or newer on Linux and the [native dependencies](getting-started.md). Tests additionally need Python 3, Python `cryptography`, OpenSSL's CLI, and `ripgrep` (`rg`). Install them with `sudo apt-get install python3-cryptography openssl ripgrep`. ```bash python3 tools/check_format.py python3 -m unittest discover -s tools -p 'test_*.py' cargo check --locked --no-default-features cargo test --locked cargo clippy --locked --all-targets -- -D warnings cargo build --locked --release bash tests/synthetic_docker_e2e.sh ``` Synthetic tests generate fresh keys, TALs, certificates and an HTTPS RRDP repository. They cover snapshot, actual delta, persistence, daemon restart and outputs without public RIR requests. Docker tests require Linux host networking. Generated keys and outputs are temporary and unsuitable as production inputs. ## Code organization - `src/cli/` parses arguments; `src/runtime/` coordinates validation. - `src/repository/` handles transport, RRDP and persistence. - `src/scheduler/` coordinates bounded workers. - `src/model/` and `src/validation/` parse and validate RPKI objects. - `src/ccr/` exports canonical state; `src/ta_constraints/` evaluates constraints. - `src/daemon/` schedules runs; logging/output modules provide diagnostics. - `tests/` contains integration tests and generated fixtures. - `docker/` contains container and Compose deployment files. Internal Rust modules are not a stable library API. The supported interface is the CLI and documented output files. Add behavior tests and update documentation when changing these interfaces. The format checker also checks files included through `include!`, which are not all traversed by `cargo fmt`. To format them, run `rustfmt --edition 2024` on the reported files, then rerun the checker. Preserve upstream license texts.
