fix(critical): fix empty token graph + aggressive settings for 24h execution
CRITICAL BUG FIX: - MultiHopScanner.updateTokenGraph() was EMPTY - adding no pools! - Result: Token graph had 0 pools, found 0 arbitrage paths - All opportunities showed estimatedProfitETH: 0.000000 FIX APPLIED: - Populated token graph with 8 high-liquidity Arbitrum pools: * WETH/USDC (0.05% and 0.3% fees) * USDC/USDC.e (0.01% - common arbitrage) * ARB/USDC, WETH/ARB, WETH/USDT * WBTC/WETH, LINK/WETH - These are REAL verified pool addresses with high volume AGGRESSIVE THRESHOLD CHANGES: - Min profit: 0.0001 ETH → 0.00001 ETH (10x lower, ~$0.02) - Min ROI: 0.05% → 0.01% (5x lower) - Gas multiplier: 5x → 1.5x (3.3x lower safety margin) - Max slippage: 3% → 5% (67% higher tolerance) - Max paths: 100 → 200 (more thorough scanning) - Cache expiry: 2min → 30sec (fresher opportunities) EXPECTED RESULTS (24h): - 20-50 opportunities with profit > $0.02 (was 0) - 5-15 execution attempts (was 0) - 1-2 successful executions (was 0) - $0.02-$0.20 net profit (was $0) WARNING: Aggressive settings may result in some losses Monitor closely for first 6 hours and adjust if needed Target: First profitable execution within 24 hours 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# Docker-Based Testing Guide
|
||||
|
||||
All MEV Bot tests run in isolated Docker containers to ensure reproducible, consistent test environments.
|
||||
|
||||
## 🐳 Quick Start
|
||||
|
||||
```bash
|
||||
# Run all tests
|
||||
./scripts/test-docker.sh
|
||||
|
||||
# Run specific test type
|
||||
./scripts/test-docker.sh unit
|
||||
./scripts/test-docker.sh integration
|
||||
./scripts/test-docker.sh race
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 📋 Available Test Types
|
||||
|
||||
### All Tests (Recommended)
|
||||
```bash
|
||||
./scripts/test-docker.sh all
|
||||
```
|
||||
|
||||
Runs complete test suite:
|
||||
1. ✅ Build verification
|
||||
2. ✅ Unit tests
|
||||
3. ✅ Race detector tests
|
||||
4. ✅ Integration tests
|
||||
5. ✅ Coverage report
|
||||
6. ✅ Linting
|
||||
7. ✅ Security scan
|
||||
|
||||
### Unit Tests
|
||||
```bash
|
||||
./scripts/test-docker.sh unit
|
||||
```
|
||||
- Tests individual components in isolation
|
||||
- Fast execution (~30 seconds)
|
||||
- No external dependencies
|
||||
- Coverage: pkg/*, internal/*
|
||||
|
||||
### Integration Tests
|
||||
```bash
|
||||
./scripts/test-docker.sh integration
|
||||
```
|
||||
- Tests component interactions
|
||||
- Slower execution (~2-5 minutes)
|
||||
- May require mock services
|
||||
- Coverage: test/integration/*
|
||||
|
||||
### Race Detector Tests
|
||||
```bash
|
||||
./scripts/test-docker.sh race
|
||||
```
|
||||
- Detects race conditions
|
||||
- Tests concurrent code paths
|
||||
- Critical for arbitrage executor
|
||||
- Coverage: pkg/arbitrage/*, pkg/scanner/*
|
||||
|
||||
### Build Verification
|
||||
```bash
|
||||
./scripts/test-docker.sh build
|
||||
```
|
||||
- Verifies compilation
|
||||
- Checks dependencies
|
||||
- Tests binary creation
|
||||

|
||||
|
||||
### Coverage Report
|
||||
```bash
|
||||
./scripts/test-docker.sh coverage
|
||||
```
|
||||
- Generates HTML coverage report
|
||||
- Output: coverage/coverage.html
|
||||
- Shows line-by-line coverage
|
||||
- Identifies untested code
|
||||
|
||||
### Security Scan
|
||||
```bash
|
||||
./scripts/test-docker.sh security
|
||||
```
|
||||
- Runs gosec security scanner
|
||||
- Checks for vulnerabilities
|
||||
- Output: coverage/gosec-report.json
|
||||
- Identifies security issues
|
||||
|
||||
### Linting
|
||||
```bash
|
||||
./scripts/test-docker.sh lint
|
||||
```
|
||||
- Runs golangci-lint
|
||||
- Checks code quality
|
||||
- Enforces style guide
|
||||
- Catches common bugs

## 🛠️ Troubleshooting
|
||||
|
||||
### Issue: "Cannot connect to Docker daemon"
|
||||
|
||||
**Solution:**
|
||||
```bash
|
||||
# Start Docker service
|
||||
sudo systemctl start docker
|
||||
|
||||
# Or on macOS
|
||||
open -a Docker
|
||||
```
|
||||
|
||||
### Issue: "Build failed - dependency errors"
|
||||
|
||||
**Solution:**
|
||||
```bash
|
||||
# Clean Docker cache
|
||||
docker-compose -f docker-compose.test.yml down --volumes
|
||||
docker system prune -af
|
||||
|
||||
# Rebuild
|
||||
./scripts/test-docker.sh build
|
||||
```
|
||||
|
||||
### Issue: "Tests timeout"
|
||||
|
||||
**Solution:**
|
||||
```bash
|
||||
# Increase timeout in docker-compose.test.yml
|
||||
services:
|
||||
test-unit:
|
||||
command: >
|
||||
sh -c "
|
||||
timeout 600 go test -v ./... # 10 minute timeout
|
||||
"
|
||||
```
|
||||
|
||||
### Issue: "Permission denied"
|
||||
|
||||
**Solution:**
|
||||
```bash
|
||||
# Fix script permissions
|
||||
chmod +x scripts/test-docker.sh
|
||||
|
||||
# Fix coverage directory
|
||||
sudo chown -R $USER:$USER coverage/
|
||||
```

|
||||
|
||||
## 📈 Best Practices
|
||||
|
||||
### Before Committing
|
||||
```bash
|
||||
# Always run full test suite
|
||||
./scripts/test-docker.sh all
|
||||
```
|
||||
|
||||
### During Development
|
||||
```bash
|
||||
# Run unit tests frequently
|
||||
./scripts/test-docker.sh unit
|
||||
|
||||
# Check race conditions
|
||||
./scripts/test-docker.sh race
|
||||
```
|
||||
|
||||
### Before Release
|
||||
```bash
|
||||
# Full validation
|
||||
./scripts/test-docker.sh all
|
||||
|
||||
# Review coverage
|
||||
open coverage/coverage.html
|
||||
|
||||
# Check security
|
||||
cat coverage/gosec-report.json | jq '.Issues'
|
||||
```

|
||||
|
||||
## 🔐 Security Considerations
|
||||
|
||||
### Test Isolation
|
||||
- ✅ Each test runs in isolated container
|
||||
- ✅ No shared state between tests
|
||||
- ✅ Clean environment every run
|
||||
|
||||
### Secrets Management
|
||||
- ❌ Never commit test credentials
|
||||
- ✅ Use environment variables
|
||||
- ✅ Mock external services
|
||||
|
||||
### Test Data
|
||||
- ✅ Use synthetic test data
|
||||
- ✅ Never use production data
|
||||
- ✅ Clear test data after run
|
||||
|
||||

|
||||
|
||||
## 📝 Adding New Tests
|
||||
|
||||
### 1. Write Test
|
||||
```go
|
||||
// pkg/arbitrage/executor_test.go
|
||||
func TestNewFeature(t *testing.T) {
|
||||
// Test implementation
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Run Locally
|
||||
```bash
|
||||
./scripts/test-docker.sh unit
|
||||
```
|
||||
|
||||
### 3. Verify Coverage
|
||||
```bash
|
||||
./scripts/test-docker.sh coverage
|
||||
open coverage/coverage.html
|
||||
```
|
||||
|
||||
### 4. Check Security
|
||||
```bash
|
||||
./scripts/test-docker.sh security
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🆘 Getting Help
|
||||
|
||||
### Check Logs
|
||||
```bash
|
||||
# View test output
|
||||
docker-compose -f docker-compose.test.yml logs test-unit
|
||||
|
||||
# Debug specific test
|
||||
docker-compose -f docker-compose.test.yml run --rm test-unit \
|
||||
go test -v -run TestProblematic ./...
|
||||
```
|
||||
|
||||
### Clean Start
|
||||
```bash
|
||||
# Remove everything and rebuild
|
||||
./scripts/test-docker.sh clean
|
||||
docker system prune -af
|
||||
./scripts/test-docker.sh all
|
||||
```
|
||||

|
||||
|
||||
**Docker-based testing ensures:**
|
||||
