test-crewai-project

Deterministic, offline testing of CrewAI crews and flows with pytest: a stub BaseLLM (shipped in references/stub_llm.py) that drives text, structured output and tool calls with no API key, asserting on the prompts crewai built, testing guardrails and flow routing, what `crewai test` really does, event listeners for debugging, and the exact tracing/telemetry env var values. Use when writing tests for a crewai project, mocking or stubbing the LLM, writing a custom BaseLLM, seeing `TypeError: ... call() got an unexpected keyword argument 'from_task'`, `ValueError: OPENAI_API_KEY is required` in CI, `TraceGrantError` in pytest, running `crewai test`, adding a BaseEventListener, or setting CREWAI_TRACING_ENABLED / CREWAI_DISABLE_TELEMETRY / OTEL_SDK_DISABLED.
