Features include test generation, test improvement suggestions, coverage analysis, docstring generation, code behavior analysis, and integration with testing frameworks. The AI understands what makes tests valuable and generates tests that actually catch bugs rather than just increasing coverage numbers. IDE integration and works with popular testing frameworks. Ideal for developers wanting better test coverage and teams practicing TDD.
