+# Local Testing for GitHub Actions
+
+This document explains how to test your GitHub Actions workflows locally before pushing to GitHub.
+
+## 🧪 Methods to Test GitHub Actions Locally
+
+### 1. **Direct Command Testing** (Recommended)
+
+Run the exact same commands that GitHub Actions uses:
+
+```bash
+# Test linting (same as CI)
+$(go env GOPATH)/bin/golangci-lint run --timeout=5m
+
+# Test building
+go build -v ./...
+
+# Test with race detection and coverage
+go test -v -race -coverprofile=coverage.out ./...
+
+# Generate coverage report
+go tool cover -html=coverage.out -o coverage.html
+
+# Run security scanner (if you have it)
+# gosec ./...
+```
+
+### 2. **Using Makefile** (Convenient)
+
+Use the local CI command:
+
+```bash
+# Install dependencies and run all CI checks
+make ci-local
+
+# Individual commands
+make lint          # Run linting
+make test-race     # Run tests with race detection
+make coverage      # Generate coverage report
+make build         # Build the project
+```
+
+### 3. **Using `act` Tool** (Full GitHub Actions Simulation)
+
+Install and use `act` to run GitHub Actions locally with Docker:
+
+```bash
+# Install act (requires Docker)
+brew install act
+
+# Run specific jobs
+act -j lint                    # Run just the lint job
+act -j test                    # Run just the test job
+act -j integration-test        # Run integration tests
+act                           # Run all jobs
+
+# Run with specific event
+act push                      # Simulate push event
+act pull_request             # Simulate PR event
+```
+
+### 4. **VS Code Extensions**
+
+- **GitHub Actions**: Syntax highlighting and validation
+- **YAML**: Better YAML editing experience
+
+## 🔧 Local Setup
+
+### Install Required Tools
+
+```bash
+# Install golangci-lint
+go install github.com/golangci/golangci-lint/cmd/golangci-lint@latest
+
+# Install goimports (for formatting)
+go install golang.org/x/tools/cmd/goimports@latest
+
+# Install act (optional, requires Docker)
+brew install act
+```
+
+### Verify Installation
+
+```bash
+# Check golangci-lint
+$(go env GOPATH)/bin/golangci-lint --version
+
+# Check Go tools
+go version
+```
+
+## 🚀 Quick Test Script
+
+Create a `test-ci.sh` script:
+
+```bash
+#!/bin/bash
+set -e
+
+echo "🔍 Running local CI tests..."
+
+echo "📦 Building..."
+go build -v ./...
+
+echo "🧪 Running tests..."
+go test -v -race ./...
+
+echo "🔍 Running linter..."
+$(go env GOPATH)/bin/golangci-lint run --timeout=5m
+
+echo "✅ All local CI tests passed!"
+```
+
+Make it executable and run:
+
+```bash
+chmod +x test-ci.sh
+./test-ci.sh
+```
+
+## 📋 Common Issues and Solutions
+
+### Linting Issues
+
+**Problem**: `golangci-lint` reports many issues
+**Solution**:
+1. Run `$(go env GOPATH)/bin/goimports -w .` to fix imports
+2. Check `.golangci.yml` configuration
+3. Fix critical issues, exclude overly strict rules
+
+**Problem**: Import formatting issues
+**Solution**:
+```bash
+$(go env GOPATH)/bin/goimports -w .
+```
+
+### Test Issues
+
+**Problem**: Tests hang or timeout
+**Solution**:
+1. Add `t.Parallel()` to tests
+2. Use in-memory databases for testing
+3. Add proper cleanup functions
+4. Set reasonable timeouts
+
+### Build Issues
+
+**Problem**: Build fails locally but works in CI
+**Solution**:
+1. Check Go version compatibility
+2. Run `go mod tidy`
+3. Ensure all dependencies are available
+
+## 🎯 Best Practices
+
+1. **Test Early**: Run local tests before every commit
+2. **Use Makefile**: Standardize common commands
+3. **Parallel Tests**: Use `t.Parallel()` for faster execution
+4. **Clean Setup**: Use proper test setup and cleanup
+5. **Reasonable Timeouts**: Don't let tests hang indefinitely
+
+## 📊 Performance Tips
+
+- **Parallel Execution**: Tests run in parallel by default
+- **In-Memory Databases**: Use `:memory:` for SQLite tests
+- **Minimal Setup**: Only create what you need for tests
+- **Proper Cleanup**: Clean up resources to avoid conflicts
