AI0-001 Implementing AI Solutions Practice Question
An AI team is deploying a real-time document intelligence service that extracts key-value pairs from invoices. The pipeline includes an LLM that calls a function to parse structured output. Which TWO testing strategies are essential before production deployment?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
An evaluation framework that compares extracted fields against ground truth for a test set of invoices
Integration tests for the API call ensure the function calling mechanism works end-to-end. An evaluation framework for LLM output quality measures extraction accuracy. Unit tests for data pipelines are important but less critical here; load testing is operational; model training tests are irrelevant.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
An evaluation framework that compares extracted fields against ground truth for a test set of invoices
Why this is correct
Measures accuracy (e.g., precision, recall) of the extraction, critical for business requirements.
- ✗
Load testing to simulate peak invoice volume (e.g., end of month)
Why it's wrong here
Important for performance but not an essential pre-deployment test for correctness.
- ✗
Regression tests on the model training pipeline to ensure the base LLM hasn't changed
Why it's wrong here
If using a hosted LLM, the model may change; but testing the training pipeline is not relevant for a pre-trained model.
- ✓
Integration tests that call the LLM API with sample invoices and verify the JSON output structure
Why this is correct
Ensures the API, function definitions, and parsing work correctly.
- ✗
Unit tests for the data pipeline that cleans and normalises invoice images
Why it's wrong here
Important but not the most essential for the LLM function calling aspect.
