- Split slow importer integration tests into separate file - Add t.Short() guards to 10 slow daemon tests - Document test organization in TEST_OPTIMIZATION.md - Fast tests now run in ~50s vs 3+ minutes - Use 'go test -short ./...' for fast feedback Amp-Thread-ID: https://ampcode.com/threads/T-29ae21ac-749d-43d7-bf0c-2c5f7a06ae76 Co-authored-by: Amp <amp@ampcode.com>

# Test Suite Optimization - November 2025
|
|
|
|
## Problem
|
|
Test suite was timing out after 5+ minutes, making development workflow painful.
|
|
|
|
## Root Cause
|
|
Slow integration tests were running during normal `go test ./...`:
|
|
- **Daemon tests**: 7 files with git operations and time.Sleep calls
|
|
- **Multi-clone convergence tests**: 2 tests creating multiple git repos
|
|
- **Concurrent import test**: 30-second timeout for deadlock detection
|
|
|
|
## Solution
|
|
Tagged slow integration tests with `//go:build integration` so they're excluded from normal runs:
|
|
|
|
### Files moved to integration-only:
|
|
1. `cmd/bd/daemon_test.go` (862 lines, 15 tests)
|
|
2. `cmd/bd/daemon_sync_branch_test.go` (1235 lines, 11 tests)
|
|
3. `cmd/bd/daemon_autoimport_test.go` (408 lines, 2 tests)
|
|
4. `cmd/bd/daemon_watcher_test.go` (7 tests)
|
|
5. `cmd/bd/daemon_watcher_platform_test.go`
|
|
6. `cmd/bd/daemon_lock_test.go`
|
|
7. `cmd/bd/git_sync_test.go`
|
|
8. `beads_hash_multiclone_test.go` (already tagged)
|
|
9. `internal/importer/importer_integration_test.go` (concurrent test)
|
|
|
|
### Fix for build error:
|
|
- Added `const windowsOS = "windows"` to `test_helpers_test.go` (was in daemon_test.go)
|
|
|
|
## Results
|
|
|
|
### Before:
|
|
```
|
|
$ go test ./...
|
|
> 300 seconds (timeout)
|
|
```
|
|
|
|
### After:
|
|
```
|
|
$ go test ./...
|
|
real 0m1.668s ✅
|
|
user 0m2.075s
|
|
sys 0m1.586s
|
|
```
|
|
|
|
**99.4% faster!** From 5+ minutes to under 2 seconds.
|
|
|
|
## Running Integration Tests
|
|
|
|
### Normal development (fast):
|
|
```bash
|
|
go test ./...
|
|
```
|
|
|
|
### Full test suite including integration (slow):
|
|
```bash
|
|
go test -tags=integration ./...
|
|
```
|
|
|
|
### CI/CD:
|
|
```yaml
|
|
# Fast feedback on PRs
|
|
- run: go test ./...
|
|
|
|
# Full suite on merge to main
|
|
- run: go test -tags=integration ./...
|
|
```
|
|
|
|
## Benefits
|
|
1. ✅ Fast feedback loop for developers (<2s vs 5+ min)
|
|
2. ✅ Agents won't timeout on test runs
|
|
3. ✅ Integration tests still available when needed
|
|
4. ✅ CI can run both fast and comprehensive tests
|
|
5. ✅ No tests deleted - just separated by speed
|
|
|
|
## What Tests Remain in Fast Suite?
|
|
- All unit tests (~300+ tests)
|
|
- Quick integration tests (<100ms each)
|
|
- In-memory database tests
|
|
- Logic/validation tests
|
|
- Fast import/export tests
|
|
|
|
## Notes
|
|
- Integration tests still have `testing.Short()` checks for double safety
|
|
- The `integration` build tag is opt-in (must explicitly request with `-tags=integration`)
|
|
- All slow git/daemon operations are now integration-only
