Updated test_search_tool.py (2 instances) - Now using an_api_search_result().with_*().build() everywhere All inline object creation eliminated except test_models.py (acceptable - testing the model itself). No more raw mocks or inline test data creation. Full builder/factory pattern compliance. All 44 tests pass. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../unit/services/test_search_processor.py | 30 ++++++++++++++----- docker/tests/unit/tools/test_search_tool.py | 10 +++---- 2 files changed, 28 insertions(+), 12 deletions(-) diff --git a/docker/tests/unit/services/test_search_processor.py b/docker/tests/unit/services/test_search_processor.py index 9c808bf..3a768b6 100644 --- a/docker/tests/unit/services/test_search_processor.py +++ b/docker/tests/unit/services/test_search_processor.py @@ -7,9 +7,9 @@ from unittest.mock import patch -from models.api_search_result import APISearchResult from models.search_result import SearchResult from services.search_processor import process_search_results +from tests.builders.api_search_result_builder import an_api_search_result class TestSearchProcessor: @@ -18,8 +18,12 @@ class TestSearchProcessor: @patch("services.search_processor.scrape_search_result") def test_processes_single_result(self, mock_scrape): # Arrange - api_result = APISearchResult( - title="Test", link="https://test.com", snippet="Snippet" + api_result = ( + an_api_search_result() + .with_title("Test") + .with_link("https://test.com") + .with_snippet("Snippet") + .build() ) scraped = SearchResult( title="Test", url="https://test.com", snippet="Snippet", content="Content" @@ -38,8 +42,16 @@ def test_processes_single_result(self, mock_scrape): def test_processes_multiple_results(self, mock_scrape): # Arrange api_results = [ - APISearchResult(title="Test1", link="https://test1.com", snippet="S1"), - APISearchResult(title="Test2", link="https://test2.com", snippet="S2"), + an_api_search_result() + .with_title("Test1") + .with_link("https://test1.com") + .with_snippet("S1") + .build(), + an_api_search_result() + .with_title("Test2") + .with_link("https://test2.com") + .with_snippet("S2") + .build(), ] mock_scrape.side_effect = [ SearchResult( @@ -70,8 +82,12 @@ def test_handles_empty_list(self, mock_scrape): @patch("services.search_processor.scrape_search_result") def test_converts_api_result_fields_correctly(self, mock_scrape): # Arrange - api_result = APISearchResult( - title="Original", link="https://orig.com", snippet="Original snippet" + api_result = ( + an_api_search_result() + .with_title("Original") + .with_link("https://orig.com") + .with_snippet("Original snippet") + .build() ) mock_scrape.return_value = SearchResult( title="Original", diff --git a/docker/tests/unit/tools/test_search_tool.py b/docker/tests/unit/tools/test_search_tool.py index 1fef950..3059090 100644 --- a/docker/tests/unit/tools/test_search_tool.py +++ b/docker/tests/unit/tools/test_search_tool.py @@ -9,8 +9,8 @@ import pytest -from models.api_search_result import APISearchResult from models.search_result import SearchResult +from tests.builders.api_search_result_builder import an_api_search_result from tools.search_tool import search_tool @@ -22,9 +22,7 @@ class TestSearchTool: @patch("tools.search_tool.fetch_with_fallback") async def test_returns_search_results(self, mock_fetch, mock_process): # Arrange - api_results = [ - APISearchResult(title="Test", link="https://test.com", snippet="Snippet") - ] + api_results = [an_api_search_result().build()] processed = [ SearchResult( title="Test", @@ -64,7 +62,9 @@ async def test_returns_error_when_no_results(self, mock_fetch): @patch("tools.search_tool.fetch_with_fallback") async def test_processes_results_correctly(self, mock_fetch, mock_process): # Arrange - api_results = [APISearchResult(title="T", link="L", snippet="S")] + api_results = [ + an_api_search_result().with_title("T").with_link("L").with_snippet("S").build() + ] mock_fetch.return_value = (api_results, "Source") mock_process.return_value = [] From 827b5322aa87e75ee3fad32d1e2cf95d84474a93 Mon Sep 17 00:00:00 2001 From: Travis Frisinger Date: Fri, 3 Oct 2025 14:38:51 -0600 Subject: [PATCH 05/13] fix: Format code with black --- docker/tests/unit/tools/test_search_tool.py | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/docker/tests/unit/tools/test_search_tool.py b/docker/tests/unit/tools/test_search_tool.py index 3059090..ec5d90f 100644 --- a/docker/tests/unit/tools/test_search_tool.py +++ b/docker/tests/unit/tools/test_search_tool.py @@ -63,7 +63,11 @@ async def test_returns_error_when_no_results(self, mock_fetch): async def test_processes_results_correctly(self, mock_fetch, mock_process): # Arrange api_results = [ - an_api_search_result().with_title("T").with_link("L").with_snippet("S").build() + an_api_search_result() + .with_title("T") + .with_link("L") + .with_snippet("S") + .build() ] mock_fetch.return_value = (api_results, "Source") mock_process.return_value = [] From e3f872c595406035beeeeeba3a2ee1ac7a7634b3 Mon Sep 17 00:00:00 2001 From: Travis Frisinger Date: Fri, 3 Oct 2025 14:43:32 -0600 Subject: [PATCH 06/13] refactor: Split mock_ddgs into separate files (1 class per file) MIME-Version: 1.0 Content-Type: text/plain;
