Overview
A design principle for constructing reusable evaluation datasets from golden test case objects. Evaluation datasets aggregate multiple golden objects into a cohesive collection that enables systematic, reproducible, and batch evaluation of AI agents across diverse scenarios.
Description
While individual golden test cases define the ground truth for single evaluation scenarios, an evaluation dataset brings them together into a structured collection that supports:
- Batch evaluation -- running all test cases through an agent and collecting scores in a single operation, rather than evaluating one case at a time.
- Reproducibility -- a fixed dataset ensures that evaluation results are comparable across different agent versions, model configurations, or prompt strategies.
- Dataset management -- datasets can be versioned, shared, and synchronized with the Confident AI platform for team collaboration.
- Coverage analysis -- a well-constructed dataset covers the range of scenarios an agent is expected to handle, including edge cases and failure modes.
The construction of evaluation datasets follows a builder pattern: golden objects are created individually (or loaded from external sources), then assembled into an EvaluationDataset that serves as the input to DeepEval's evaluation pipeline.
Usage
Evaluation dataset construction is used when:
- Setting up systematic evaluation pipelines for AI agents.
- Creating regression test suites that are run on every code change.
- Building benchmark datasets for comparing agent implementations.
- Synchronizing evaluation data between local development and the Confident AI platform.
DATASET_CONSTRUCTION(goldens G1, G2, ..., Gn):
1. CREATE individual Golden objects for each test scenario
2. ASSEMBLE goldens into an EvaluationDataset
3. OPTIONALLY push the dataset to the Confident AI platform for versioning
4. USE the dataset as input to the evaluation pipeline
5. COLLECT and analyze results across all test cases
Theoretical Basis
This principle draws from:
- Test suite construction -- from software testing methodology, a test suite is a collection of test cases designed to achieve specific coverage goals. An evaluation dataset is the agent evaluation analog of a test suite, providing systematic coverage of expected agent behavior.
- Dataset management patterns -- borrows from data engineering practices for versioning, sharing, and maintaining datasets over time. This ensures evaluation results remain comparable as the dataset evolves.
The key insight is that individual test cases are necessary but not sufficient for robust evaluation. A well-constructed dataset provides the breadth and depth of coverage needed to identify agent weaknesses, track quality trends, and make informed decisions about agent deployment.
