# Testing Guide
|
|
|
|
## Overview
|
|
|
|
The beads project has a comprehensive test suite with **~41,000 lines of code** across **205 files** in `cmd/bd` alone.
|
|
|
|
## Test Performance
|
|
|
|
- **Total test time:** ~3 minutes (excluding broken tests)
|
|
- **Package count:** 20+ packages with tests
|
|
- **Compilation overhead:** ~180 seconds (most of the total time)
|
|
- **Individual test time:** Only ~3.8 seconds combined for all 313 tests in cmd/bd
|
|
|
|
## Running Tests
|
|
|
|
### Quick Start
|
|
|
|
```bash
|
|
# Run all tests (auto-skips known broken tests)
|
|
make test
|
|
|
|
# Or directly:
|
|
./scripts/test.sh
|
|
|
|
# Run specific package
|
|
./scripts/test.sh ./cmd/bd/...
|
|
|
|
# Run specific test pattern
|
|
./scripts/test.sh -run TestCreate ./cmd/bd/...
|
|
|
|
# Verbose output
|
|
./scripts/test.sh -v
|
|
```
|
|
|
|
### Environment Variables
|
|
|
|
```bash
|
|
# Set custom timeout (default: 3m)
|
|
TEST_TIMEOUT=5m ./scripts/test.sh
|
|
|
|
# Enable verbose output
|
|
TEST_VERBOSE=1 ./scripts/test.sh
|
|
|
|
# Run specific pattern
|
|
TEST_RUN=TestCreate ./scripts/test.sh
|
|
```
|
|
|
|
### Advanced Usage
|
|
|
|
```bash
|
|
# Skip additional tests beyond .test-skip
|
|
./scripts/test.sh -skip SomeSlowTest
|
|
|
|
# Run with custom timeout
|
|
./scripts/test.sh -timeout 5m
|
|
|
|
# Combine flags
|
|
./scripts/test.sh -v -run TestCreate ./internal/beads/...
|
|
```
|
|
|
|
## Known Broken Tests
|
|
|
|
Tests in `.test-skip` are automatically skipped. Current broken tests:
|
|
|
|
1. **TestFallbackToDirectModeEnablesFlush** (GH #355)
|
|
- Location: `cmd/bd/direct_mode_test.go:14`
|
|
- Issue: Database deadlock, hangs for 5 minutes
|
|
- Impact: Makes test suite extremely slow
|
|
|
|
2. **TestFindJSONLPathDefault** (GH #356)
|
|
- Location: `internal/beads/beads_test.go:175`
|
|
- Issue: Expects `issues.jsonl` but code returns `beads.jsonl`
|
|
- Impact: Assertion failure
|
|
|
|
## For Claude Code / AI Agents
|
|
|
|
When running tests during development:
|
|
|
|
### Best Practices
|
|
|
|
1. **Use the test script:** Always use `./scripts/test.sh` instead of `go test` directly
|
|
- Automatically skips known broken tests
|
|
- Uses appropriate timeouts
|
|
- Consistent with CI/CD
|
|
|
|
2. **Target specific tests when possible:**
|
|
```bash
|
|
# Instead of running everything:
|
|
./scripts/test.sh
|
|
|
|
# Run just what you changed:
|
|
./scripts/test.sh -run TestSpecificFeature ./cmd/bd/...
|
|
```
|
|
|
|
3. **Compilation is the bottleneck:**
|
|
- The 180-second compilation time dominates
|
|
- Individual tests are fast
|
|
- Use `-run` to avoid recompiling unnecessarily
|
|
|
|
4. **Check for new failures:**
|
|
```bash
|
|
# If you see a new failure, check if it's known:
|
|
cat .test-skip
|
|
```
|
|
|
|
### Adding Tests to Skip List
|
|
|
|
If you discover a broken test:
|
|
|
|
1. File a GitHub issue documenting the problem
|
|
2. Add to `.test-skip`:
|
|
```bash
|
|
# Issue #NNN: Brief description
|
|
TestNameToSkip
|
|
```
|
|
3. Tests in `.test-skip` support regex patterns
|
|
|
|
## Test Organization
|
|
|
|
### Slowest Tests (>0.05s)
|
|
|
|
The top slow tests in cmd/bd:
|
|
- `TestDoctorWithBeadsDir` (1.68s) - Only significantly slow test
|
|
- `TestFlushManagerDebouncing` (0.21s)
|
|
- `TestDebouncer_*` tests (0.06-0.12s each) - Intentional sleeps for concurrency testing
|
|
- `TestMultiWorkspaceDeletionSync` (0.12s)
|
|
|
|
Most tests are <0.01s and very fast.
|
|
|
|
### Package Structure
|
|
|
|
```
|
|
cmd/bd/ - Main CLI tests (82 test files, most of the suite)
|
|
internal/beads/ - Core beads library tests
|
|
internal/storage/ - Storage backend tests (SQLite, memory)
|
|
internal/rpc/ - RPC protocol tests
|
|
internal/*/ - Various internal package tests
|
|
```
|
|
|
|
## Continuous Integration
|
|
|
|
The test script is designed to work seamlessly with CI/CD:
|
|
|
|
```yaml
|
|
# Example GitHub Actions
|
|
- name: Run tests
|
|
run: make test
|
|
```
|
|
|
|
## Debugging Test Failures
|
|
|
|
### Get detailed output
|
|
```bash
|
|
./scripts/test.sh -v ./path/to/package/...
|
|
```
|
|
|
|
### Run a single test
|
|
```bash
|
|
./scripts/test.sh -run '^TestExactName$' ./cmd/bd/...
|
|
```
|
|
|
|
### Check which tests are being skipped
|
|
```bash
|
|
./scripts/test.sh 2>&1 | head -5
|
|
```
|
|
|
|
Output shows:
|
|
```
|
|
Running: go test -timeout 3m -skip TestFoo|TestBar ./...
|
|
Skipping: TestFoo|TestBar
|
|
```

## Contributing
|
|
|
|
When adding new tests:
|
|
|
|
1. Keep tests fast (<0.1s if possible)
|
|
2. Use `t.Parallel()` for independent tests
|
|
3. Clean up resources in `t.Cleanup()` or `defer`
|
|
4. Avoid sleeps unless testing concurrency
|
|
|
|
When tests break:
|
|
|
|
1. Fix them if possible
|
|
2. If unfixable right now, file an issue and add to `.test-skip`
|
|
3. Document the issue in `.test-skip` with issue number
