From a896a3502e1fbfebc3e1be57cc81b31f9aed3060 Mon Sep 17 00:00:00 2001 From: Andrew Trott Date: Tue, 19 Aug 2025 11:59:00 -0700 Subject: [PATCH 1/3] feat: add optional unique suffixes to test failure table names Adds configuration options to append unique suffixes to test failure tables, enabling parallel test execution and preserving historical test data. New configurations: - store_failures_unique: Enable unique table names (default: false) - store_failures_suffix: Suffix strategy (invocation_id, timestamp, date, hour, custom) This is fully backward compatible as it's opt-in and doesn't affect existing workflows.

Add unit tests for all suffix strategies (invocation_id, timestamp, date, hour, custom) - Add tests for backward compatibility (feature disabled by default) - Add tests for parallel execution scenarios - Add integration test template for database verification - Add changelog entry per contributing guidelines Tests cover: - Different suffix strategies working correctly - Backward compatibility maintained - Parallel runs creating different tables - Default behavior unchanged when feature not enabled --- .../unreleased/Features-20240819-120000.yaml | 6 + .../test_unique_store_failures.py | 264 ++++++++++++++++++ 2 files changed, 270 insertions(+) create mode 100644 dbt-adapters/.changes/unreleased/Features-20240819-120000.yaml create mode 100644 dbt-tests-adapter/src/dbt/tests/adapter/store_failures/test_unique_store_failures.py diff --git a/dbt-adapters/.changes/unreleased/Features-20240819-120000.yaml b/dbt-adapters/.changes/unreleased/Features-20240819-120000.yaml new file mode 100644 index 000000000..153547e09 --- /dev/null +++ b/dbt-adapters/.changes/unreleased/Features-20240819-120000.yaml @@ -0,0 +1,6 @@ +kind: Features +body: Add optional unique suffixes to test failure table names for parallel execution support +time: 2024-08-19T12:00:00-00:00 +custom: + Author: andtrott + Issue: "1276" \ No newline at end of file diff --git a/dbt-tests-adapter/src/dbt/tests/adapter/store_failures/test_unique_store_failures.py b/dbt-tests-adapter/src/dbt/tests/adapter/store_failures/test_unique_store_failures.py new file mode 100644 index 000000000..3659254a1 --- /dev/null +++ b/dbt-tests-adapter/src/dbt/tests/adapter/store_failures/test_unique_store_failures.py @@ -0,0 +1,264 @@ +""" +Tests for unique test failure table names feature. +This validates that the store_failures_unique configuration +creates tables with appropriate suffixes. +""" + +import pytest +from datetime import datetime +from unittest.mock import patch + +from dbt.tests.util import run_dbt, check_relation_has_expected_schema + + +# Simple model to test against +models__simple_model = """ +select 1 as id, 'Alice' as name +union all +select 2 as id, 'Bob' as name +union all +select null as id, 'Charlie' as name -- This will fail not_null test +""" + +# Test configuration with unique suffix enabled +test_yml__unique_suffix_invocation = """ +version: 2 + +models: + -
