dstest

Deterministic Simulation Testing for containerised services.

Write Lua scripts to define, control, and verify chaos experiments on Docker containers with reproducible fault injection.

Installation

From crates.io:

cargo install dstest

Or build from source:

git clone https://github.com/bxrne/dstest
cd dstest
cargo build --release

Quick Start

cat examples/basic.lua | cargo run

Overview

dstest lets you write Lua scripts that define test subjects (Docker containers), inject faults (pause, kill, resource deprivation), and verify service resilience. All experiments are deterministic when seeded, making them reproducible across runs.

Examples

• basic.lua - Minimal setup with HTTP checks
• coroutine.lua - User-controlled fault injection with coroutines
• response-time.lua - Response time validation with oracle predicates

Documentation

See DOCS.md for the full Lua API reference.

Requirements

• Docker daemon running
• Rust 1.85+ (uses 2024 edition)
