From 8cc46965c1a231434498900df9da938f8d7761a7 Mon Sep 17 00:00:00 2001 From: starmen1265 Date: Tue, 17 Mar 2026 21:54:42 +0800 Subject: [PATCH] test(08-02): add failing tests for comment crawling - Test crawl_comments returns CommentsResult - Test comments use hot sorting (order=hot) - Test comment has required fields (content, author, like_count) - Test no nested replies (first-level only) - Test include_comments parameter control Co-Authored-By: Claude Opus 4.6 --- tests/test_crawler/test_comment_crawler.py | 172 +++++++++++++++++++++ 1 file changed, 172 insertions(+) create mode 100644 tests/test_crawler/test_comment_crawler.py diff --git a/tests/test_crawler/test_comment_crawler.py b/tests/test_crawler/test_comment_crawler.py new file mode 100644 index 0000000..ef23d98 --- /dev/null +++ b/tests/test_crawler/test_comment_crawler.py @@ -0,0 +1,172 @@ +"""Tests for Zhihu comment crawling functionality""" + +import pytest +from unittest.mock import Mock, patch, MagicMock + +from kb_workflow.crawler.zhihu_crawler import ZhihuCrawler +from kb_workflow.crawler.models import CommentData, CommentsResult + + +class TestCommentCrawler: + """Tests for comment crawling functionality.""" + + @pytest.fixture + def crawler(self): + """Create ZhihuCrawler instance for testing.""" + return ZhihuCrawler(headless=True) + + @pytest.fixture + def mock_comment_response(self): + """Sample comment API response data. + + Mimics the structure of /api/v4/comment_v5/{type}/{id}/comments response. + """ + return { + "data": [ + { + "id": 111, + "content": "This is a hot comment", + "author": {"name": "User A", "url_token": "user-a"}, + "created_time": 1234567890, + "like_count": 100, + "child_comment_count": 5, + "is_author": False + }, + { + "id": 222, + "content": "Author reply", + "author": {"name": "Author", "url_token": "author"}, + "created_time": 1234567900, + "like_count": 50, + "child_comment_count": 0, + "is_author": True + } + ], + "paging": {"totals": 100} + } + + def test_crawl_comments_returns_comments_result(self, crawler, mock_comment_response): + """crawl_comments returns CommentsResult.""" + with patch.object(crawler, '_get_cookie', return_value="test_cookie"): + with patch('kb_workflow.crawler.zhihu_crawler.PlaywrightBrowser') as MockBrowser: + mock_browser = MockBrowser.return_value + mock_response = MagicMock() + mock_response.status = 200 + mock_response.json.return_value = mock_comment_response + mock_browser.page.request.get.return_value = mock_response + + result = crawler.crawl_comments("answers", 12345) + + assert isinstance(result, CommentsResult) + assert result.content_type == "answers" + assert result.content_id == 12345 + + def test_comments_are_hot_order(self, crawler, mock_comment_response): + """Comments use hot (popular) sorting.""" + with patch.object(crawler, '_get_cookie', return_value="test_cookie"): + with patch('kb_workflow.crawler.zhihu_crawler.PlaywrightBrowser') as MockBrowser: + mock_browser = MockBrowser.return_value + mock_response = MagicMock() + mock_response.status = 200 + mock_response.json.return_value = mock_comment_response + mock_browser.page.request.get.return_value = mock_response + + crawler.crawl_comments("answers", 12345) + + # Verify API URL contains order=hot + call_args = mock_browser.page.request.get.call_args + assert "order=hot" in call_args[0][0] + + def test_comment_has_required_fields(self, crawler, mock_comment_response): + """Each comment contains required fields.""" + with patch.object(crawler, '_get_cookie', return_value="test_cookie"): + with patch('kb_workflow.crawler.zhihu_crawler.PlaywrightBrowser') as MockBrowser: + mock_browser = MockBrowser.return_value + mock_response = MagicMock() + mock_response.status = 200 + mock_response.json.return_value = mock_comment_response + mock_browser.page.request.get.return_value = mock_response + + result = crawler.crawl_comments("answers", 12345) + + assert len(result.comments) == 2 + comment = result.comments[0] + assert comment.content == "This is a hot comment" + assert comment.author.name == "User A" + assert comment.like_count == 100 + + def test_no_nested_replies(self, crawler, mock_comment_response): + """Do not expand nested replies -
