Runtime test generation framework

GenTests for Python

Runtime test generation framework

Define GenTestCase blueprints with parameter sets; the framework generates a test for each combination, reducing boilerplate and increasing coverage.

Key concepts

AI-Powered Generation

Use a Large Language Model (e.g., Gemini) with a RAG system to auto-generate test parameters. The RAG fetches context from internal docs (API specs), and the LLM creates a dictionary of valid, invalid, and edge-case inputs for your GenTestCase.

Black-Box Mocking

For black-box testing, patch your app's HTTP client to redirect traffic to a local Active Stub Server. The stub server queries the GenTests generator for dynamic, context-aware responses for each test, allowing you to test an unmodified application.

Data Collection During Generation and "live documentation"

As tests are generated and run, the framework can collect valuable data, such as:

• Request/response payloads from mocked services.
• Application logs emitted during the test.
• Performance metrics like response times.

This data can be aggregated into a report, offering insights into the application's behavior under different scenarios and aiding in debugging. This collected data can then be fed into a corporate RAG system, creating a form of "live documentation" that reflects the application's actual, tested behavior.

Running the Generator

You can tag your GenTestCase tests and run them selectively with your test runner.

This will start test generation:

Django:

$ ./manage.py test animals --tag=generator

Pytest:

$ pytest tests/test_mod.py -m=generator
