HermeticByExpectedOutputCountInRange¶

TL;DR — Performs a hermetic test by comparing the count of a given output in a session to a given expected minimum and maximum

When to use¶

Adds up the number of items in the configured output names across the selected sessions and checks whether the total falls between a minimum and a maximum inclusive boundary.

This is the range-based form of the exact-count hermetic check. It is useful when a flow is allowed to produce some controlled variation but still must stay inside a defined envelope.

YAML configuration¶

Use the hook name in the matching runtime section, then place hook-specific fields under the configuration object shown in the examples below.

Minimal example¶

Sessions:
  - Name: SampleSession

Assertions:
  - Name: HermeticByExpectedOutputCountInRangeAssertion
    Assertion: HermeticByExpectedOutputCountInRange
    SessionNames:
      - SampleSession

    AssertionConfiguration:
      OutputNames:
        - Reply
      ExpectedMinimumCount: 2
      ExpectedMaximumCount: 4

Realistic example¶

This snippet counts how many items were saved under Reply for SampleSession.

The assertion passes when the count is between 2 and 4 inclusive. Counts below 2 or above 4 fail the assertion.

Edge cases¶

• Missing required configuration keys fail schema validation before the hook runs.
• Keep hook names and referenced session or data-source names aligned with the surrounding YAML.
