UnitCon: Synthesizing Targeted Unit Tests for Java Runtime Exceptions
We present UNITCON, a system for synthesizing targeted unit tests for runtime exceptions in Java programs. Targeted unit tests aim to reveal a bug at a specific location in the program under test. This capability benefits various tasks in software development, such as patch testing, crash reproduction, or static analysis alarm inspection. However, conventional unit test generation tools are mainly designed for regression tests by maximizing code coverage; hence they are not effective at such target-specific tasks. In this paper, we propose a novel synthesis technique that effectively guides the search for targeted unit tests. The key idea is to use static analysis to prune and prioritize the search space by estimating the semantics of candidate test cases. This allows us to efficiently focus on promising unit tests that are likely to reveal the target Exception. According to our experiments on a suite of Java programs, our approach significantly outperforms the state-of-the-art unit test generation tools.

Cosmos 3A is the first room in the Cosmos 3 wing.
When facing the main Cosmos Hall, access to the Cosmos 3 wing is on the left, close to the stairs. The area is accessed through a large door with the number “3”, which will stay open during the event.
