Configuration Testing for Borg at Google

Explore a novel approach to configuration testing for Google's Borg cluster management service in this 15-minute conference talk from ACM SIGPLAN's CONFLANG23. Dive into the challenges of managing complex configurations using Google Configuration Language (GCL) and its Borg-specific dialect, BCL. Learn how Google addressed the growing complexity of configuration languages by developing a unique unit testing tool for Borg deployment configurations. Discover the limitations of traditional unit testing methods for configuration languages and understand why alternative approaches are necessary to maintain development velocity while ensuring configuration safety. Gain insights into how this innovative testing tool has been successfully implemented and positively received by hundreds of engineers at Google.
