ChatUniTest
By Zhejiang University ACES. Category: Unit test generation. Homepage
The ChatUniTest README describes it as a research framework from Zhejiang University for generating unit tests with a large language model. It builds adaptive focal context for the code under test and applies a generation, validation and repair loop to the tests it produces. The chatunitest-maven-plugin generates JUnit tests for Java projects. It runs locally with an OpenAI API key or a local model endpoint. The plugin is released under the MIT licence.
