"""Tests for OpenLineage event emitter module.

This module contains unit and integration tests for constructing OpenLineage
events with dataQualityAssertions facets and emitting them to Correlator.

Test Coverage:
    - construct_event(): Build OpenLineage events with test results
    - emit_event(): Send events to OpenLineage backend
    - group_tests_by_dataset(): Group tests by target dataset
    - dataQualityAssertions facet structure validation

Implementation: Task 1.3 - OpenLineage Event Emitter
