However, the audit identified several patterns that reduce the actual effectiveness of the test suite: **over-reliance on mocking** (167 @patch decorators), **weak assertions** that always pass, and **missing tests for critical error handling paths**.

The "Always Passes" Assertion Pattern - -**Problem**: Several tests use assertions that can never fail, regardless of implementation correctness. - -**Evidence**: -```python -# tests/test_integration_comprehensive.py:625 -assert len(filtered) >= 0 # May or may not be in range depending on test date - -# tests/smoke/test_production_health.py:366 -assert len(archive) >= 0, "Archive has negative conferences?" -``` - -**Impact**: These assertions provide zero validation. An empty result or broken implementation would still pass. - -**Fix**: -```python -# Instead of: -assert len(filtered) >= 0 - -# Use specific expectations: -assert len(filtered) == expected_count -# Or at minimum: -assert len(filtered) > 0, "Expected at least one filtered conference" -``` - -**Verification**: Comment out the filtering logic - the test should fail, but currently passes. - ---- - -### 2. Over-Mocking Hides Real Bugs - -**Problem**: Many tests mock so extensively that no real code executes. The test validates mock configuration, not actual behavior. - -**Evidence** (`tests/test_integration_comprehensive.py:33-50`): -```python -@patch("main.sort_data") -@patch("main.organizer_updater") -@patch("main.official_updater") -@patch("main.get_tqdm_logger") -def test_complete_pipeline_success(self, mock_logger, mock_official, mock_organizer, mock_sort): - """Test complete pipeline from data import to final output.""" - mock_logger_instance = Mock() - mock_logger.return_value = mock_logger_instance - - # Mock successful execution of all steps - mock_official.return_value = None - mock_organizer.return_value = None - mock_sort.return_value = None - - # Execute complete pipeline - main.main() - - # All assertions verify mocks, not actual behavior - mock_official.assert_called_once() - mock_organizer.assert_called_once() -``` - -**Impact**: This test passes if `main.main()` calls mocked functions in order, but would pass even if: -- The actual import functions are completely broken -- Data processing corrupts conference data -- Files are written with wrong content - -**Fix**: Create integration tests with real (or minimal stub) implementations: -```python -def test_complete_pipeline_with_real_data(self, tmp_path): - """Test pipeline with real data processing.""" - # Create actual test data files - test_data = [{"conference": "Test", "year": 2025, ...}] - conf_file = tmp_path / "_data" / "conferences.yml" - conf_file.parent.mkdir(parents=True) - with conf_file.open("w") as f: - yaml.dump(test_data, f) - - # Run real pipeline (with network mocked) - with patch("tidy_conf.links.requests.get"): - sort_yaml.sort_data(base=str(tmp_path), skip_links=True) - - # Verify actual output - with conf_file.open() as f: - result = yaml.safe_load(f) - assert result[0]["conference"] == "Test" -``` - -**Verification**: Introduce a bug in `sort_yaml.sort_data()` - the current test passes, a real integration test would fail. - ---- - -### 3. Tests That Don't Verify Actual Behavior - -**Problem**: Several tests verify that functions execute without exceptions but don't check correctness of results. - -**Evidence** (`tests/test_import_functions.py:70-78`): -```python -@patch("import_python_official.load_conferences") -@patch("import_python_official.write_df_yaml") -def test_main_function(self, mock_write, mock_load): - """Test the main import function.""" - mock_load.return_value = pd.DataFrame() - - # Should not raise an exception - import_python_official.main() - - mock_load.assert_called_once() -``` - -**Impact**: This only verifies the function calls `load_conferences()` - not that: -- ICS parsing works correctly -- Conference data is extracted properly -- Output format is correct - -**Fix**: -```python -def test_main_function_produces_valid_output(self, tmp_path): - """Test that main function produces valid conference output.""" - with patch("import_python_official.requests.get") as mock_get: - mock_get.return_value.content = VALID_ICS_CONTENT - - result_df = import_python_official.main() - - # Verify actual data extraction - assert len(result_df) > 0 - assert "conference" in result_df.columns - assert all(result_df["link"].str.startswith("http")) -``` - ---- - -### 4. Fuzzy Match Tests With Weak Assertions - -**Problem**: Fuzzy matching is critical for merging conference data, but tests don't verify matching accuracy. - -**Evidence** (`tests/test_interactive_merge.py:52-83`): -```python -def test_fuzzy_match_similar_names(self): - """Test fuzzy matching with similar but not identical names.""" - df_yml = pd.DataFrame({"conference": ["PyCon US"], ...}) - df_csv = pd.DataFrame({"conference": ["PyCon United States"], ...}) - - with patch("builtins.input", return_value="y"): - merged, _remote = fuzzy_match(df_yml, df_csv) - - # Should find a fuzzy match - assert not merged.empty - assert len(merged) >= 1 # WEAK: doesn't verify correct match -``` - -**Impact**: Doesn't verify that: -- The correct conferences were matched -- Match scores are reasonable -- False positives are avoided - -**Fix**: -```python -def test_fuzzy_match_similar_names(self): - """Test fuzzy matching with similar but not identical names.""" - # ... setup ... - - merged, _remote = fuzzy_match(df_yml, df_csv) - - # Verify correct match was made - assert len(merged) == 1 - assert merged.iloc[0]["conference"] == "PyCon US" # Kept original name - assert merged.iloc[0]["link"] == "https://new.com" # Updated link - -def test_fuzzy_match_rejects_dissimilar_names(self): - """Verify dissimilar conferences are NOT matched.""" - df_yml = pd.DataFrame({"conference": ["PyCon US"], ...}) - df_csv = pd.DataFrame({"conference": ["DjangoCon EU"], ...}) - - merged, remote = fuzzy_match(df_yml, df_csv) - - # Should NOT match - these are different conferences - assert len(merged) == 1 # Original PyCon only - assert len(remote) == 1 # DjangoCon kept separate -``` - ---- - -### 5. Date Handling Edge Cases Missing - -**Problem**: Date logic is critical for a deadline tracking site, but several edge cases are untested. - -**Evidence** (`utils/tidy_conf/date.py`): -```python -def clean_dates(data): - """Clean dates in the data.""" - # Handle CFP deadlines - if data[datetimes].lower() not in tba_words: - try: - tmp_time = datetime.datetime.strptime(data[datetimes], dateformat.split(" ")[0]) - # ... - except ValueError: - continue # SILENTLY IGNORES MALFORMED DATES -``` - -**Missing tests for**: -- Malformed date strings (e.g., "2025-13-45") -- Timezone edge cases (deadline at midnight in AoE vs UTC) -- Leap year handling -- Year boundary transitions - -**Fix** - Add edge case tests: -```python -class TestDateEdgeCases: - def test_malformed_date_handling(self): - """Test that malformed dates don't crash processing.""" - data = {"cfp": "invalid-date", "start": "2025-06-01", "end": "2025-06-03"} - result = clean_dates(data) - # Should handle gracefully, not crash - assert "cfp" in result - - def test_timezone_boundary_deadline(self): - """Test deadline at timezone boundary.""" - # A CFP at 23:59 AoE should be different from 23:59 UTC - conf_aoe = Conference(cfp="2025-02-15 23:59:00", timezone="AoE", ...) - conf_utc = Conference(cfp="2025-02-15 23:59:00", timezone="UTC", ...) - - assert sort_by_cfp(conf_aoe) != sort_by_cfp(conf_utc) - - def test_leap_year_deadline(self): - """Test CFP on Feb 29 of leap year.""" - data = {"cfp": "2024-02-29", "start": "2024-06-01", "end": "2024-06-03"} - result = clean_dates(data) - assert result["cfp"] == "2024-02-29 23:59:00" -``` - ---- - -## High Priority Findings - -### 6. Link Checking Tests Mock the Wrong Layer - -**Problem**: Link checking tests mock `requests.get` but don't test the actual URL validation logic. - -**Evidence** (`tests/test_link_checking.py:71-110`): -```python -@patch("tidy_conf.links.requests.get") -def test_link_check_404_error(self, mock_get): - # ... extensive mock setup ... - with patch("tidy_conf.links.tqdm.write"), patch("tidy_conf.links.attempt_archive_url"), - patch("tidy_conf.links.get_cache") as mock_get_cache, - patch("tidy_conf.links.get_cache_location") as mock_cache_location, - patch("builtins.open", create=True): - # 6 patches just to test one function! -``` - -**Impact**: So much is mocked that the test doesn't verify: -- Actual HTTP request formation -- Response parsing logic -- Archive.org API integration - -**Fix**: Use `responses` or `httpretty` to mock at HTTP level: -```python -import responses - -@responses.activate -def test_link_check_404_fallback_to_archive(self): - """Test that 404 links fall back to archive.org.""" - responses.add(responses.GET, "https://example.com", status=404) - responses.add( - responses.GET, - "https://archive.org/wayback/available", - json={"archived_snapshots": {"closest": {"available": True, "url": "..."}}} - ) - - result = check_link_availability("https://example.com", date(2025, 1, 1)) - assert "archive.org" in result -``` - ---- - -### 7. No Tests for Data Corruption Prevention - -**Problem**: The "conference name corruption" test exists but doesn't actually verify the fix works. - -**Evidence** (`tests/test_interactive_merge.py:323-374`): -```python -def test_conference_name_corruption_prevention(self): - """Test prevention of conference name corruption bug.""" - # ... setup ... - - result = merge_conferences(df_merged, df_remote_processed) - - # Basic validation - we should get a DataFrame back with conference column - assert isinstance(result, pd.DataFrame) # WEAK - assert "conference" in result.columns # WEAK - # MISSING: Actually verify names aren't corrupted! -``` - -**Fix**: -```python -def test_conference_name_corruption_prevention(self): - """Test prevention of conference name corruption bug.""" - original_name = "Important Conference With Specific Name" - df_yml = pd.DataFrame({"conference": [original_name], ...}) - - # ... processing ... - - # Actually verify the name wasn't corrupted - assert result.iloc[0]["conference"] == original_name - assert result.iloc[0]["conference"] != "0" # The actual bug: index as name - assert result.iloc[0]["conference"] != str(result.index[0]) -``` - ---- - -### 8. Newsletter Filter Logic Untested - -**Problem**: Newsletter generation filters conferences by deadline, but tests don't verify filtering accuracy. - -**Evidence** (`tests/test_newsletter.py`): -The tests mock `load_conferences` and verify `print` was called, but don't test: -- Filtering by days parameter works correctly -- CFP vs CFP_ext priority is correct -- Boundary conditions (conference due exactly on cutoff date) - -**Missing tests**: -```python -def test_filter_excludes_past_deadlines(self): - """Verify past deadlines are excluded from newsletter.""" - now = datetime.now(tz=timezone.utc).date() - conferences = pd.DataFrame({ - "conference": ["Past", "Future"], - "cfp": [now - timedelta(days=1), now + timedelta(days=5)], - "cfp_ext": [pd.NaT, pd.NaT], - }) - - filtered = newsletter.filter_conferences(conferences, days=10) - - assert len(filtered) == 1 - assert filtered.iloc[0]["conference"] == "Future" - -def test_filter_uses_cfp_ext_when_available(self): - """Verify extended CFP takes priority over original.""" - now = datetime.now(tz=timezone.utc).date() - conferences = pd.DataFrame({ - "conference": ["Extended"], - "cfp": [now - timedelta(days=5)], # Past - "cfp_ext": [now + timedelta(days=5)], # Future - }) - - filtered = newsletter.filter_conferences(conferences, days=10) - - # Should be included because cfp_ext is in future - assert len(filtered) == 1 -``` - ---- - -## Medium Priority Findings - -### 9.

Extensive jQuery Mocking Obscures Real Behavior - -**Status**: ✅ COMPLETE - All test files refactored to use real jQuery - -**Original Problem**: Frontend unit tests created extensive jQuery mocks (200-300 lines per test file) that simulated jQuery behavior, making tests fragile and hard to maintain. - -**Resolution**: Removed ~740 lines of mock code across 7 files, replaced with real jQuery from setup.js + minimal plugin mocks. - -**Refactored Files**: -- `action-bar.test.js` - ✅ Removed 20-line mock (source is vanilla JS) -- `conference-manager.test.js` - ✅ Removed 50-line mock (source is vanilla JS) -- `search.test.js` - ✅ Now uses real jQuery, only mocks $.fn.countdown -- `favorites.test.js` - ✅ Removed 178-line mock, uses real jQuery -- `dashboard.test.js` - ✅ Removed 200-line mock, uses real jQuery -- `dashboard-filters.test.js` - ✅ Removed 130-line mock, uses real jQuery -- `conference-filter.test.js` - ✅ Removed 230-line mock, uses real jQuery - -**Minimal Plugin Mocks** (only plugins unavailable in test environment): -```javascript -// Bootstrap plugins -$.fn.modal = jest.fn(function() { return this; }); -$.fn.toast = jest.fn(function() { return this; }); -// jQuery plugins -$.fn.countdown = jest.fn(function() { return this; }); -$.fn.multiselect = jest.fn(function() { return this; }); -``` - -**Benefits Achieved**: -- Tests now verify real jQuery behavior, not mock behavior -- Removed ~740 lines of fragile mock code -- Tests are more reliable and closer to production behavior -- No more "mock drift" when jQuery updates - -**Commit**: `test: refactor all frontend tests to use real jQuery instead of mocks` - -**Pattern for Future Tests**: -```javascript -// 1.

d59c5bc677fa5a78e2fe1e5b13dddd7b4f6694ae Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 15 Jan 2026 22:44:23 +0000 Subject: [PATCH 20/29] test: audit and remediate test quality issues Phase 1 - Audit: - Analyzed all 467 tests across 23 test files - Identified 13 flaky time-dependent tests - Found vapid assertions and incomplete tests - Created comprehensive TEST_AUDIT.md with findings Phase 2 - Remediation: - Fix: Added @freeze_time decorator to 13 tests in test_newsletter.py to eliminate time-dependent flakiness - Fix: Replaced vapid 'pass' statement with real assertions in test_interactive_merge.py::test_fuzzy_match_similar_names - Fix: Added missing assertions to incomplete test in test_normalization.py::test_expands_conf_to_conference Phase 3 - Enhancement: - Added 4 new Hypothesis property-based tests: - test_cfp_datetime_roundtrip: CFP datetime parsing roundtrip - test_any_valid_cfp_time_accepted: Any valid time format works - test_cfp_before_conference_valid: CFP before conference is valid - test_deduplication_is_idempotent: Dedup is idempotent Metrics: - Before: 90% sound tests, 13 unfrozen time tests, 15 hypothesis tests - After: 98% sound tests, 0

Fix all ruff linting issues across test files: - Use specific type: ignore codes - Combine nested if statements (SIM102) - Use tuple for startswith (PIE810) - Use list.extend instead of loop append (PERF401) - Add timezone to datetime.now() calls (DTZ005/DTZ007) - Use list unpacking instead of concatenation (RUF005) - Replace ambiguous Unicode with escape sequences (RUF001/RUF003) - Add strict= to zip() calls (B905) - Remove unused variables (F841, RUF059) - Move imports to top of file (E402) - Use r""" for docstrings with backslashes (D301) - Rename non-returning fixtures with leading underscore (PT004) - Use X | Y syntax in isinstance calls (UP038) - Update tests for new fuzzy_match API that returns 3 values: (result, remote, report) instead of (result, remote) - Fix test assertions to handle conference name normalization (e.g., "PyCon US" -> "PyCon USA") -
