Overview
A testing pattern that validates the end-to-end behavior of an InferenceGraph pipeline by sending test inputs and verifying the combined output format.
Description
Pipeline Validation confirms that the InferenceGraph is correctly routing requests through its nodes, that all component services are responding, and that the output format matches expectations. Different graph types produce different output formats:
- Sequence: Final step's prediction output
- Ensemble: Merged JSON with per-component keys
- Splitter: One component's output (varies per request due to weighted random)
Usage
Use this after deploying an InferenceGraph to verify the pipeline is working end-to-end before directing production traffic to it.
Theoretical Basis
# Validation model (NOT implementation code)
1. Send known test inputs to the graph URL
2. Verify response format matches expected graph type output
3. Sequence: response == last step's output
4. Ensemble: response has keys for all steps
5. Splitter: response has key for one step
6. Switch: response from matched condition step
