Test Oracle Automation in the era of LLMs

The effectiveness of a test suite in detecting faults highly depends on the correctness and completeness of its test oracles. LLMs have already demonstrated remarkable proficiency in tackling diverse software testing tasks, such as automated test generation and program repair. This paper aims to enable discussions on the potential of using LLMs for test oracle automation, along with the challenges that may emerge during the generation of various types of oracles. Additionally, our aim is to initiate discussions on the primary threats that SE researchers must consider when employing LLMs for oracle automation, encompassing concerns regarding oracle deficiencies and data leakages.
