Concurrency bugs are notoriously hard to detect and reproduce. Controlled concurrency testing (CCT) techniques aim to offer a solution, where a \textit{scheduler} explores the space of possible interleavings of a concurrent program looking for bugs. Since the set of possible interleavings is typically very large, these schedulers employ heuristics that prioritize the search to ``interesting'' subspaces. However, current heuristics are typically tuned to specific bug patterns, which limits their effectiveness in practice.

In this paper, we present \texttt{QL}, a learning-based CCT framework where the likelihood of an action being selected by the scheduler is influenced by earlier explorations. We leverage the classical Q-learning algorithm to explore the space of possible interleavings, allowing the exploration to adapt to the program under test, unlike previous techniques. We have implemented and evaluated \texttt{QL} on a set of microbenchmarks, complex protocols, as well as production cloud services. In our experiments, we found \texttt{QL} to consistently outperform the state-of-the-art in CCT.
