Property testing has risen to popularity in the past years due to its ability to find edge cases and other hard to reproduce bugs. But for programmers new to property testing it can be difficult to see how to use property tests to exercise entire systems.

In this paper we'll look at a real world use case for property tests and examine the tools and techniques used by the authors to find and reliably reproduce race conditions in a concurrent, distributed system.
