Test bundles, new tests, support for new Python runtimes

Test bundles, new tests, support for new Python runtimes

We’re very excited to introduce test bundles to the Openlayer platform! Easily create a set of tests related to use cases or policies of interest, such as the EU AI Act, OWASP, agentic workflows, data quality, and more. Comprehensive test bundles ensure you catch errors across all your key use cases before they slip through the cracks.

Along with test bundles, we’ve added some new tests to our library: groundedness for LLMs, toxicity score, checks for prompt injections, and checks to see if the outputs recommend a competitor company. You can create these tests today in the Openlayer app!
