helix_ir.test.generate_tests(schema: Schema, sensitivity: float = 1.5) → list[Test][source]¶

Generate data quality tests based on schema metadata.

Parameters:

schema – The schema to generate tests for.
sensitivity – Multiplier for expected cardinality deviations. Higher = more permissive (fewer false positives).

Returns:

A list of Test objects.

helix_ir.test.run_test(test: Test, data: list[dict[str, Any]]) → TestResult[source]¶: Run a test against in-memory data.
