Testing and Continuous Delivery

Modern, distributed systems are complex and present numerous challenges: concurrency, process crashes, message loss, duplication, or reordering.

How can developers confidently test distributed systems instead of continuously dreading the next hard-to-catch and hard-to-reproduce Heisenbug?

Deterministic Simulation Testing is a powerful testing technique that eliminates uncertainty－or rather non-determinism－and ensures that your system is tested exhaustively and every single test is reproducible.

Using a systems modeling approach, we will accurately and concisely discuss Deterministic Simulation Testing. In addition, we will explore real-world implementation of this technique in production in projects such as FoundationDB, TigerBeetle, and Resonate.
