"""Tests for dbt artifact parser module.

This module contains unit tests for parsing dbt artifacts (run_results.json
and manifest.json) and extracting dataset information for OpenLineage events.

Test Coverage:
    - parse_run_results(): Parse run_results.json file
    - parse_manifest(): Parse manifest.json file
    - extract_dataset_info(): Resolve dataset from test node
    - map_test_status(): Map dbt status to boolean

Implementation: Task 1.2 - dbt Artifact Parser
