Tests in Openlayer let you codify expectations for your AI system and data. They help you ensure that your data, models, and outputs remain reliable, safe, and compliant over time. .

​
Where tests apply

Tests are a common layer across all workflows in Openlayer:

Observability

Monitor live requests after deployment.

Offline testing

Validate changes in CI/CD pipelines.

Data quality monitoring

Track the health of your tables and features.
Together, these allow you to test your system both pre- and post-production.

​
Getting started with tests

There are three levels of entry, from fastest to most flexible:

​
1. Apply a bundle

Bundles are pre-packaged sets of tests for common use cases. They allow you to apply broad coverage with a single step, without having to configure each test individually. Examples include:
  • Agentic bundle: evaluate the performance of agentic and RAG systems with metrics like faithfulness, relevance, and more.
  • Usage bundle: track system usage via cost, tokens, latency, and more.
  • OWASP bundle: check for common security issues such as prompt injection, hallucinations, and more.
  • EU AI Act bundle: align with regulatory requirements, including fairness, transparency, and more.
  • Data quality bundle: catch data quality issues such as missing values, duplicates, anomalies, and more.
We are continuously adding and improving bundles, so stay tuned for updates.

​
2. Pick individual tests from the catalog

Openlayer provides 100+ individual tests. You can browse all tests and assemble your own test suite for fine-grained control.

​
3. Define your own tests

If the built-in catalog does not cover your use case, you can create custom tests with custom metrics. This allows you to encode domain-specific checks alongside the standard ones.
By combining bundles, catalog tests, and custom metrics, you can build a test suite that fits your system today and adapts as it evolves.
