Microsoft Open Sources code-testing-generator: a Polyglot Unit-Test Agent That Hits 92.1% Task Completion Versus 78.9% for Stock Copilot

Microsoft open sourced code-testing-generator, a polyglot agent that writes unit tests by first analyzing the repository to understand framework and conventions, then planning and verifying the tests it creates. The agent achieved 92.1% task completion on an internal 152-task benchmark compared to 78.9% for stock GitHub Copilot using the same model. The improvement enables teams to fill gaps in test coverage across polyglot codebases without manual configuration or external dependencies.
