About this paper

Kefan Li, Hongyue Yu, Yuan Yuan

DCAware completes one missing assertion in an existing regression test by combining relevant code context with selected values queried from a running test. It writes the assertion without an execution-and-repair loop. On 500 Java test instances, GPT-5-mini achieved an 88.20% Pass Rate, versus 73.20% for ChatAssert; on 183 shared passed instances, its Shared Kill Golden score was 92.83%, versus 86.31%.
