Created `TestAutoFlushSuite` and `TestAutoImportSuite` with shared DB +2. Converted 18 individual tests to subtests +3. Reduced from 14 DB setups to 2 + +### Problems Encountered + +#### 1. **Deadlock Issue** +- Tests call `flushToJSONL()` which accesses the database +- Test cleanup (from `newTestStore()`) tries to close the database +- Results in database lock contention and test timeouts +- Stack trace shows: `database/sql.(*DB).Close()` waiting while `flushToJSONL()` is accessing DB + +#### 2. **Global State Manipulation** +These tests heavily manipulate package-level globals: +- `autoFlushEnabled`, `isDirty`, `flushTimer` +- `store`, `storeActive`, `storeMutex` +- `dbPath` (used to compute JSONL path dynamically) +- `flushFailureCount`, `lastFlushError` + +#### 3. **Integration Test Characteristics** +- Tests simulate end-to-end flush/import workflows +- Tests capture stderr to verify error messages +- Tests manipulate filesystem state directly +- Tests create directories to force error conditions + +### Key Differences from P1 Tests + +| Aspect | P1 Tests (create, dep, etc.) | main_test.go | +|--------|------------------------------|--------------| +| **DB Usage** | Pure DB operations | Global state + DB + filesystem | +| **Isolation** | Data-level only | Requires process-level isolation | +| **Cleanup** | Simple | Complex (timers, goroutines, mutexes) | +| **Pattern** | CRUD operations | Workflow simulation | + +### Why Shared DB Doesn't Work + +1. **`jsonlPath` is computed dynamically** from `dbPath` via `findJSONLPath()` + - Not a global variable like in old tests + - Changes to `dbPath` affect where JSONL files are written/read + +2. **Tests need to control exact JSONL paths** for: + - Creating files to force errors (making JSONL a directory) + - Verifying files were/weren't created + - Touching files to simulate git pull scenarios + +3. **Concurrent access issues**: + - Background flush operations may trigger during test cleanup + - Global mutexes protect state but cause deadlocks with shared DB + +### What Tests Actually Do + +#### Auto-Flush Tests (9 tests) +- Test global state flags (`isDirty`, `autoFlushEnabled`) +- Test timer management (`flushTimer`) +- Test concurrency (goroutines calling `markDirtyAndScheduleFlush()`) +- Simulate program exit (PersistentPostRun behavior) +- Force error conditions by making JSONL path a directory + +#### Auto-Import Tests (9 tests) +- Test JSONL -> DB sync when JSONL is newer +- Test merge conflict detection (literal `<<<<<<<` markers in file) +- Test JSON-encoded conflict markers (false positive prevention) +- Test status transition invariants (closed_at management) +- Manipulate file timestamps with `os.Chtimes()` + +## Recommended Approach + +### Option 1: Leave As-Is (RECOMMENDED) +**Rationale**: These are integration tests, not unit tests. The overhead of 14 DB setups is acceptable for: +- Tests that manipulate global state +- Tests that simulate complex workflows +- Tests that are relatively fast already (~0.5s each) + +**Expected speedup**: Minimal (2-3x at most) vs. complexity cost + +### Option 2: Refactor Without Shared DB +**Changes**: +1. Keep individual test functions (not suite) +2. Reduce DB setups by **reusing test stores within related test groups** +3. Add helpers to reset global state between tests +4. Document which tests can share vs. need isolation + +**Example**: +```go +func TestAutoFlushGroup(t *testing.T) { + tmpDir := t.TempDir() + testDB := filepath.Join(tmpDir, "test.db") + testStore := newTestStore(t, testDB) + + // Helper to reset state + resetState := func() { + autoFlushEnabled = true + isDirty = false + if flushTimer != nil { + flushTimer.Stop() + flushTimer = nil + } + } + + t.Run("DirtyMarking", func(t *testing.T) { + resetState() + // test... + }) + + t.Run("Disabled", func(t *testing.T) { + resetState() + // test... + }) +} +``` + +### Option 3: Mock/Stub Approach +**Changes**: +1. Introduce interfaces for `flushToJSONL` and `autoImportIfNewer` +2. Mock the filesystem operations +3. Test state transitions without actual DB/filesystem + +**Trade-offs**: More refactoring, loses integration test value + +## Files Modified (Reverted) +- `cmd/bd/main_test.go` - Reverted to original +- `cmd/bd/duplicates_test.go` - Fixed unused import (kept fix) + +## Lessons Learned + +1. **Not all tests benefit from shared DB pattern** + - Integration tests need isolation + - Global state manipulation requires careful handling + +2. **P1 test pattern assumes**: + - Pure DB operations + - No global state + - Data-level isolation sufficient + +3. **Test classification matters**: + - Unit tests: Share DB ✓ + - Integration tests: Need isolation ✓ + - Workflow tests: Need full process isolation ✓ + +## Next Steps + +1. **Document in TEST_SUITE_AUDIT.md** that main_test.go is P2 but **NOT a good candidate** for shared DB pattern +2. **Update audit classification**: Move main_test.go to "Special Cases" category +3. **Focus P2 efforts** on `integrity_test.go` and `export_import_test.go` instead + +## References +- Original issue: bd-1rh (Phase 2 test suite optimization) +- Pattern source: `label_test.go`, P1 refactored files +- Related: bd-159 (test config issues), bd-270 (merge conflict detection) diff --git a/cmd/bd/main_test.go b/cmd/bd/main_test.go index b0d5499f..0f70de3c 100644 --- a/cmd/bd/main_test.go +++ b/cmd/bd/main_test.go @@ -156,7 +156,7 @@ func TestAutoFlushDebounce(t *testing.T) { } // Wait for debounce to complete -
