LLM-mock – Record real LLM API responses once, replay them in tests forever
The article introduces llm-mock, a tool designed to record and replay LLM API calls for testing purposes. It allows developers to run tests without incurring costs or requiring API keys after the initial recording. The tool integrates seamlessly with pytest, enabling deterministic testing of LLM responses.
- ▪llm-mock allows recording real LLM responses and replaying them in tests without needing an API key.
- ▪The tool helps reduce costs associated with API calls during continuous integration runs.
- ▪It intercepts HTTP calls at the transport layer, requiring no changes to existing application code.
