# Audit and Testing Guide
|
||||
|
||||
Comprehensive guide for testing and auditing the MEV bot codebase.
|
||||
|
||||
## Quick Reference
|
||||
|
||||
```bash
|
||||
# Run everything
|
||||
./scripts/dev.sh test all # All tests
|
||||
./scripts/dev.sh audit # Code quality audit
|
||||
./scripts/dev.sh check-compliance # SPEC.md compliance
|
||||
./scripts/dev.sh check-docs # Documentation coverage
|
||||
|
||||
# Specific tests
|
||||
./scripts/dev.sh test unit # Unit tests only
|
||||
./scripts/dev.sh test coverage # Coverage report
|
||||
./scripts/dev.sh test race # Race detection
|
||||
./scripts/dev.sh test bench # Benchmarks
|
||||
```
|
||||
|
||||
## Testing Suite
|
||||
|
||||
### 1. Unit Tests
|
||||
|
||||
Fast tests that verify individual components in isolation.
|
||||
|
||||
```bash
|
||||
# Run all unit tests
|
||||
./scripts/dev.sh test unit
|
||||
|
||||
# Run tests for specific package
|
||||
./scripts/dev.sh test pkg sequencer
|
||||
|
||||
# Verbose output
|
||||
./scripts/test.sh unit true
|
||||
```
|
||||
|
||||
**What it tests:**
|
||||
- Individual function correctness
|
||||
- Edge cases and error handling
|
||||
- Component behavior in isolation
|
||||
|
||||
**Files:** All `*_test.go` files in `pkg/`
|
||||
|
||||
### 2. Integration Tests
|
||||
|
||||
Tests that verify components work together correctly.
|
||||
|
||||
```bash
|
||||
# Run integration tests
|
||||
./scripts/dev.sh test integration
|
||||
```
|
||||
|
||||
**What it tests:**
|
||||
- Sequencer → Swap Filter → Pool Cache pipeline
|
||||
- Database operations
|
||||
- External service interactions
|
||||
|
||||
**Files:** `tests/*_integration_test.go`
|
||||
|
||||
### 3. Race Detection
|
||||
|
||||
Detects data races in concurrent code.
|
||||
|
||||
```bash
|
||||
# Run with race detector
|
||||
./scripts/dev.sh test race
|
||||
```
|
||||
|
||||
**What it checks:**
|
||||
- Concurrent access to shared state
|
||||
- Mutex usage correctness
|
||||
- Channel safety
|
||||
|
||||
**Important:** Always run before committing concurrent code changes.
|
||||
|
||||
### 4. Benchmarks
|
||||
|
||||
Performance testing for critical paths.
|
||||
|
||||
```bash
|
||||
# Run benchmarks
|
||||
./scripts/dev.sh test bench
|
||||
```
|
||||
|
||||
**What it measures:**
|
||||
- Swap parsing throughput
|
||||
- Pool cache lookup speed
|
||||
- Channel message processing rate
|
||||
|
||||
**Files:** Functions named `Benchmark*` in `*_test.go`
|
||||
|
||||
### 5. Coverage Report
|
||||
|
||||
Measures test coverage percentage.
|
||||
|
||||
```bash
|
||||
# Generate coverage report
|
||||
./scripts/dev.sh test coverage
|
||||
```
|
||||
|
||||
**Output:**
|
||||
- `coverage/coverage.out` - Coverage data
|
||||
- `coverage/coverage.html` - HTML report (open in browser)
|
||||
|
||||
**Target:** >70% coverage for production code
|
||||
|
||||
## Audit Suite
|
||||
|
||||
### 1. Codebase Audit
|
||||
|
||||
Comprehensive code quality and security check.
|
||||
|
||||
```bash
|
||||
./scripts/dev.sh audit
|
||||
```
|
||||
|
||||
**Checks:**
|
||||
|
||||
#### Code Quality
|
||||
- `go vet` warnings
|
||||
- TODO/FIXME comments
|
||||
- panic() usage
|
||||
- Error handling patterns
|
||||
|
||||
#### Security
|
||||
- Hardcoded secrets
|
||||
- SQL injection risks
|
||||
- Command injection
|
||||
- Unsafe pointer usage
|
||||
|
||||
#### Concurrency
|
||||
- Race condition risks
|
||||
- Mutex coverage
|
||||
- Channel usage
|
||||
|
||||
#### SPEC.md Compliance
|
||||
- Hardcoded function selectors (forbidden)
|
||||
- HTTP RPC in sequencer (forbidden)
|
||||
- Blocking operations in hot paths (forbidden)
|
||||
- Manual ABI files (forbidden)
|
||||
|
||||
**Exit codes:**
|
||||
- 0: No issues
|
||||
- 1: Issues found (review required)
|
||||
|
||||
### 2. Documentation Coverage
|
||||
|
||||
Verifies all code is properly documented.
|
||||
|
||||
```bash
|
||||
./scripts/dev.sh check-docs
|
||||
```
|
||||
|
||||
**Checks:**
|
||||
|
||||
- Package `doc.go` files
|
||||
- Exported function comments
|
||||
- Exported type comments
|
||||
- README files in key directories
|
||||
- Project documentation (SPEC.md, CLAUDE.md, etc.)
|
||||
- Inline comment density
|
||||
|
||||
**Target:** >80% documentation coverage
|
||||
|
||||
### 3. SPEC.md Compliance
|
||||
|
||||
Ensures code adheres to all SPEC.md requirements.
|
||||
|
||||
```bash
|
||||
./scripts/dev.sh check-compliance
|
||||
```
|
||||
|
||||

- 0: Fully compliant
|
||||
- 1: Violations found
|
||||
|
||||
## Continuous Integration
|
||||
|
||||
### Pre-Commit Checks
|
||||
|
||||
Run before every commit:
|
||||
|
||||
```bash
|
||||
# Quick validation
|
||||
./scripts/dev.sh test unit
|
||||
./scripts/dev.sh check-compliance
|
||||
|
||||
# Full pre-commit
|
||||
./scripts/dev.sh test all
|
||||
./scripts/dev.sh audit
|
||||
```
|
||||
|
||||
### Pre-Push Checks
|
||||
|
||||
Run before pushing to remote:
|
||||
|
||||
```bash
|
||||
# Comprehensive check
|
||||
./scripts/dev.sh test all
|
||||
./scripts/dev.sh test race
|
||||
./scripts/dev.sh audit
|
||||
./scripts/dev.sh check-compliance
|
||||
./scripts/dev.sh check-docs
|
||||
```
|
||||
|
||||
### Pre-Release Checks
|
||||
|
||||
Run before creating a release:
|
||||
|
||||
```bash
|
||||
# Full audit
|
||||
./scripts/dev.sh test coverage # Ensure >70%
|
||||
./scripts/dev.sh test bench # Check performance
|
||||
./scripts/dev.sh audit # Security & quality
|
||||
./scripts/dev.sh check-compliance # SPEC.md adherence
|
||||
./scripts/dev.sh check-docs # Documentation complete
|
||||
```
|
||||
|
||||
## Test Writing Guidelines
|
||||
|
||||
### Unit Test Example
|
||||
|
||||
```go
|
||||
// pkg/sequencer/swap_filter_test.go
|
||||
func TestSwapFilter_DetectUniswapV2Swap(t *testing.T) {
|
||||
// Setup
|
||||
filter := NewSwapFilter(logger, poolCache)
|
||||
|
||||
// Create test message with known swap
|
||||
msg := map[string]interface{}{
|
||||
"messages": []interface{}{
|
||||
map[string]interface{}{
|
||||
"message": map[string]interface{}{
|
||||
"l2Msg": base64EncodedSwapTx,
|
||||
},
|
||||
},
|
||||
},
|
||||
}
|
||||
|
||||
// Execute
|
||||
filter.ProcessMessage(msg)
|
||||
|
||||
// Verify
|
||||
select {
|
||||
case swap := <-filter.SwapCh():
|
||||
assert.Equal(t, "UniswapV2", swap.Protocol.Name)
|
||||
assert.NotEqual(t, common.Address{}, swap.Pool.Address)
|
||||
case <-time.After(time.Second):
|
||||
t.Fatal("timeout waiting for swap event")
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Benchmark Example
|
||||
|
||||
```go
|
||||
// pkg/pools/cache_bench_test.go
|
||||
func BenchmarkPoolCache_Lookup(b *testing.B) {
|
||||
cache := NewPoolCache(...)
|
||||
|
||||
// Pre-populate cache
|
||||
for i := 0; i < 1000; i++ {
|
||||
cache.AddOrUpdate(generateTestPool())
|
||||
}
|
||||
|
||||
addr := testPoolAddress
|
||||
|
||||
b.ResetTimer()
|
||||
for i := 0; i < b.N; i++ {
|
||||
cache.Get(addr)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Integration Test Example
|
||||
|
||||
```go
|
||||
// tests/sequencer_integration_test.go
|
||||
func TestSequencerToPoolCache_Pipeline(t *testing.T) {
|
||||
// Start real sequencer feed
|
||||
reader := sequencer.NewReader(config)
|
||||
swapFilter := sequencer.NewSwapFilter(logger, poolCache)
|
||||
|
||||
// Connect pipeline
|
||||
go reader.Start(ctx)
|
||||
go swapFilter.Start(ctx)
|
||||
|
||||
// Wait for real swaps from mainnet
|
||||
timeout := time.After(30 * time.Second)
|
||||
swapsFound := 0
|
||||
|
||||
for swapsFound < 5 {
|
||||
select {
|
||||
case swap := <-swapFilter.SwapCh():
|
||||
// Verify swap is valid
|
||||
assert.NotEqual(t, common.Address{}, swap.Pool.Address)
|
||||
swapsFound++
|
||||
case <-timeout:
|
||||
t.Fatalf("only found %d swaps in 30s", swapsFound)
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Common Issues
|
||||
|
||||
### Issue: Tests timeout
|
||||
|
||||
**Cause:** Blocking operations in tests
|
||||
|
||||
**Fix:**
|
||||
```go
|
||||
// Bad
|
||||
time.Sleep(10 * time.Second)
|
||||
|
||||
// Good
|
||||
select {
|
||||
case result := <-resultCh:
|
||||
// ...
|
||||
case <-time.After(5 * time.Second):
|
||||
t.Fatal("timeout")
|
||||
}
|
||||
```
|
||||
|
||||
### Issue: Race detector reports races
|
||||
|
||||
**Cause:** Unprotected shared state
|
||||
|
||||
**Fix:**
|
||||
```go
|
||||
// Bad
|
||||
var counter int
|
||||
func increment() { counter++ }
|
||||
|
||||
// Good
|
||||
var mu sync.Mutex
|
||||
var counter int
|
||||
func increment() {
|
||||
mu.Lock()
|
||||
defer mu.Unlock()
|
||||
counter++
|
||||
}
|
||||
```
|
||||
|
||||
### Issue: Low coverage
|
||||
|
||||
**Cause:** Missing test cases
|
||||
|
||||
**Fix:**
|
||||
1. Identify uncovered code: `go tool cover -func=coverage/coverage.out`
|
||||
2. Add tests for edge cases
|
||||
3. Test error paths
|
||||
4. Add table-driven tests
|
||||
|
||||
## Metrics and Monitoring
|
||||
|
||||
### Coverage Trends
|
||||
|
||||
Track coverage over time:
|
||||
|
||||
```bash
|
||||
# Generate report
|
||||
./scripts/dev.sh test coverage
|
||||
|
||||
# View current coverage
|
||||
grep "total:" coverage/coverage.out
|
||||
```
|
||||
|
||||
### Performance Baselines
|
||||
|
||||
Establish performance baselines:
|
||||
|
||||
```bash
|
||||
# Run benchmarks
|
||||
./scripts/dev.sh test bench > benchmarks/baseline-$(date +%Y%m%d).txt
|
||||
|
||||
# Compare with previous
|
||||
benchstat benchmarks/baseline-old.txt benchmarks/baseline-new.txt
|
||||
```
|
||||
|
||||
## CI/CD Integration
|
||||
|
||||
### GitHub Actions Example
|
||||
|
||||
```yaml
|
||||
name: Test Suite
|
||||
|
||||
