ETA Exploration Traces


ETA (Exploratory Testing Architecture) is a testing framework that explores the execution of a distributed application, looking for bugs that are provoked by particular sequences of events caused by non-determinism such as timing and asynchrony. ETA was developed for Omega, a cluster management system developed at Google.

As part of its functionality, ETA provides estimates for when its exploratory testing will finish. Achieving accurate runtime estimations is a significant research challenge, and so in order to stimulate interest, and foster research in improving these estimates, we have made available traces of a number of ETA’s real-world exploratory test runs.
