Test configuration

The testing: section keeps behavior checks in the policy-config.yaml file that you lint and deploy.

Start​

This example passes the two commands verdictan policy lint and verdictan policy test --json.

Pack layout​

verdictan policy test evaluates JSON golden tests in tests/. It also evaluates inline testing.suites[] cases.

Keep the tests/ directory in the pack layout that verdictan init makes if most tests are inline.

Test suite structure​

testing:
  default_threshold: 0.8
  suites:
    - name: suite-name
      description: Human-readable purpose
      assertions: []
      cases: []

Top-level fields​

FieldTypeDescription
default_thresholdnumberThe runner uses this default when an assertion does not set a threshold.
suitesarrayThis field contains inline suite definitions.

Test suite fields​

FieldTypeNecessaryDescription
namestringyesThis is the unique suite name.
descriptionstringnoThis field contains a readable purpose.
assertionsarraynoThe runner applies these assertions to each case in the suite.
casesarraynoThis field contains the test cases.

For verdictan policy test, make runnable suites from active assertions, inputs, and specified verdicts.

            verdict: allow
            reason_code: ok

Output assertion suite​

Use upstream_response to score or examine a model response after the policy chain runs.

testing:
  default_threshold: 0.8
  suites:
    - name: answer-quality
      assertions:
        - type: word-count
          config:
            min: 50
      cases:
        - name: rich-answer
          input:
            messages:
              - role: user
                content: "Explain photosynthesis in one paragraph."
            upstream_response:
              choices:
                - message:
                    content: "Photosynthesis is the process plants use to convert light energy into chemical energy stored in glucose. Chlorophyll captures sunlight, water supplies electrons, and carbon dioxide provides the carbon that is built into sugars. Oxygen is released as a by-product. The stored glucose then supports plant growth, repair, and metabolism."
          expected:
            verdict: allow
            reason_code: ok
