feat: add _with_context variants for generic tests (#975)
* feat: add _with_context variants for generic tests Adds six new elementary generic tests that extend common dbt/dbt_utils/dbt_expectations tests with a `context_columns` parameter, allowing users to specify which additional columns are returned alongside failing rows. If `context_columns` is omitted, all columns are returned. New tests: - elementary.not_null_with_context - elementary.accepted_range_with_context - elementary.expect_column_values_to_not_be_null_with_context - elementary.expect_column_values_to_be_unique_with_context - elementary.expect_column_values_to_match_regex_with_context - elementary.relationships_with_context Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix: address CodeRabbit review comments on _with_context tests - accepted_range_with_context: raise compiler error when both min_value and max_value are omitted, preventing a silent always-pass condition - expect_column_values_to_be_unique_with_context: use explicit column list from adapter.get_columns_in_relation instead of SELECT * to prevent the computed n_records window column from leaking into the output Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * style: apply sqlfmt formatting to _with_context tests Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
