What is Finding Min-repros in Database Software about?

Testing and debugging database system applications is often challenging and time consuming. A database tester (or DB tester for short) has to detect a problem, determine why it happened, set up an environment to reproduce it, and then create a fix to resolve the problem. In many cases, problems appear in complex scenarios, and thus the setup to reproduce a problem may be large and difficult to understand. This makes the task of finding the root cause of a problem very challenging. As a consequence, a very arduous task for a DB tester is finding a min-repro -a process of weeding out irrelevant inputs and finding the simplest way to reproduce a problem. Currently, a great deal of searching for minrepros is carried out manually using non-database-specific tools, which is both slow and error-prone. In this paper, we present a system designed to ease and speed up searches for min-repros in database-related products. The min-repro system employs several effective tools, including: the novel simplification transformations, the high-level language for creating custom scripts and automation, the record-and-replay functionality, and the visualization of results and the search space.
