# FIPS Testing

Integration and simulation test harnesses for FIPS, using Docker
containers running the full protocol stack.

## Test Harnesses

### [static/](static/) -- Static Docker Network

Fixed topologies with manual scripts for building, config generation,
connectivity tests (ping, iperf), and network impairment (netem).
Useful for deterministic debugging and validating specific topology
configurations.

| Topology    | Nodes | Transport | Description                      |
| ----------- | ----- | --------- | -------------------------------- |
| mesh        | 5     | UDP       | Sparse mesh, 6 links, multi-hop  |
| chain       | 5     | UDP       | Linear chain, max 4-hop paths    |
| mesh-public | 5+1   | UDP       | Mesh with external public node   |
| tcp-chain   | 3     | TCP       | Linear chain over TCP (port 443) |

### [chaos/](chaos/) -- Stochastic Simulation

Automated network testing with configurable node counts, topology
algorithms (random geometric, Erdos-Renyi, chain, explicit), and fault
injection (netem mutation, link flaps, traffic generation, node
churn). 16 scenarios covering general stress testing, cost-based parent
selection, mixed link technologies (fiber/Bluetooth/WiFi), and
transport-specific validation (UDP, TCP, Ethernet). Scenarios are
defined in YAML and executed via a Python harness that manages the full
lifecycle: topology generation, Docker orchestration, fault scheduling,
log collection, and analysis.
