## Overview
|
|
|
|

|
|
- Request ID and context-aware logging support
|
|
|
|
### ✅ 0.4 CI/CD Pipeline
|
|
- GitHub Actions workflow for automated testing and linting
|
|

|
|
- Automated build and test execution
|
|
|
|
### ✅ 0.5 Dependency Injection and Bootstrap
|
|
- DI container using Uber FX in `internal/di/`
|
|
- Provider functions for core services
|
|
- Application entry point in `cmd/platform/main.go`
|
|
- Lifecycle management with graceful shutdown
|
|
|
|
## Verification Instructions
|
|
|
|
### Prerequisites
|
|
- Go 1.24 or later installed
|
|
- Make installed (optional, for using Makefile commands)
|
|
|
|
### 1. Verify Project Structure
|
|
|
|
```bash
|
|
# Check Go module
|
|
go mod verify
|
|
|
|
# Check directory structure
|
|
ls -la
|
|
# Should see: cmd/, internal/, pkg/, config/, docs/, etc.
|
|
```
|
|
|
|
### 2. Verify Configuration System
|
|
|
|
```bash
|
|
# Build the application
|
|
go build ./cmd/platform
|
|
|
|
# Check if config files exist
|
|
ls -la config/
|
|
# Should see: default.yaml, development.yaml, production.yaml
|
|
|
|
# Test config loading (will fail without database, but config should load)
|
|
# This will be tested in Epic 1 when database is available
|
|
```
|
|
|
|
### 3. Verify Logging System
|
|
|
|
```bash
|
|
# Run tests for logging
|
|
go test ./internal/logger/...
|
|
|
|
# Expected output: Tests should pass
|
|
```
|
|
|
|
### 4. Verify CI/CD Pipeline
|
|
|
|
```bash
|
|
# Run linting (if golangci-lint is installed)
|
|
make lint
|
|
|
|
# Run tests
|
|
make test
|
|
|
|
# Build the application
|
|
make build
|
|
# Binary should be created in bin/platform
|
|
|
|
# Run all checks
|
|
make check
|
|
```
|
|
|
|
### 5. Verify Dependency Injection
|
|
|
|
```bash
|
|
# Build the application
|
|
go build ./cmd/platform
|
|
|
|
# Check if DI container compiles
|
|
go build ./internal/di/...
|
|
|
|
# Run the application (will fail without database in Epic 1)
|
|
# go run ./cmd/platform/main.go
|
|
```
|
|
|
|
### 6. Verify Application Bootstrap
|
|
|
|
```bash
|
|
# Build the application
|
|
make build
|
|
|
|
# Check if binary exists
|
|
ls -la bin/platform
|
|
|
|
# The application should be ready to run (database connection will be tested in Epic 1)
|
|
```
|
|
|
|
## Testing Configuration
|
|
|
|
The configuration system can be tested by:
|
|
|
|
1. **Modifying config files**: Edit `config/default.yaml` and verify changes are loaded
|
|
2. **Environment variables**: Set `ENVIRONMENT=production` and verify production config is loaded
|
|
3. **Type safety**: Configuration access methods (`GetString`, `GetInt`, etc.) provide compile-time safety
|
|
|
|
## Testing Logging
|
|
|
|
The logging system can be tested by:
|
|
|
|
1. **Unit tests**: Run `go test ./internal/logger/...`
|
|
2. **Integration**: Logging will be tested in Epic 1 when HTTP server is available
|
|
3. **Format switching**: Change `logging.format` in config to switch between JSON and console output
|
|
|
|
## Common Issues and Solutions
|
|
|
|
### Issue: `go mod verify` fails
|
|
**Solution**: Run `go mod tidy` to update dependencies
|
|
|
|
### Issue: Build fails
|
|
**Solution**: Ensure Go 1.24+ is installed and all dependencies are downloaded (`go mod download`)
|
|
|
|
### Issue: Config not loading
|
|
**Solution**: Ensure `config/default.yaml` exists and is in the correct location relative to the binary
|
|
|
|
## Next Steps
|
|
|
|
After verifying Epic 0, proceed to [Epic 1](../epic1/SUMMARY.md) to set up the database and HTTP server, which will enable full end-to-end testing of the configuration and logging systems.
