Abstract

Big data applications are now widely used to process massive amounts of data we create every day. When a failure occurs in a big data application, debugging at the system-level input can be expensive due to the large amount of data being processed. This paper introduces a test generation framework for effectively generating method-level tests to facilitate debugging of big data applications. This is achieved by running a big data application with the real dataset and by automatically recording input to a small number of method executions, which we refer to as method-level tests, while preserving certain code coverage, e.g., line coverage. When debugging, a developer could inspect the execution of these method-level tests, instead of the entire program execution with the real dataset, which could be time-consuming. We implemented the framework and applied the framework to seven algorithms in the WEKA tool. The initial results show that only a very small number of method-level tests need to be recorded to preserve code coverage. Furthermore, these tests could kill between 53.08% to 96.89% of the mutants generated using a third-party tool. This suggests that the framework could significantly reduce the efforts required for debugging big data applications.
