# BDD Testing with Godog # BDD Testing Framework
This package implements Behavior-Driven Development (BDD) testing using the Godog framework. This directory contains the Behavior-Driven Development (BDD) testing framework for the dance-lessons-coach project, implementing the architecture described in ADR 0024.
## Important Requirements for Step Definitions ## 🗺️ Architecture Overview
### Step Pattern Matching The BDD framework follows a modular, isolated test suite architecture with these key components:
Godog has **very specific requirements** for step pattern matching. To avoid "undefined" warnings: ### 📁 Directory Structure
1. **Use the exact regex pattern** that Godog suggests in its error messages ```
2. **Use the exact parameter names** that Godog suggests (`arg1, arg2`, etc.) pkg/bdd/
3. **Match the feature file syntax exactly** including quotes and JSON formatting ├── README.md # This file
├── context/ # Feature-specific test contexts
### Example │ ├── auth_context.go # Authentication test context
│ └── config_context.go # Configuration test context
**Feature file step:** ├── helpers/ # Test synchronization helpers
```gherkin │ └── synchronization.go # Wait functions and utilities
Then the response should be "{\"message\":\"Hello world!\"}" ├── parallel/ # Parallel test execution
│ ├── port_manager.go # Port allocation system
│ └── resource_monitor.go # Resource tracking
├── steps/ # Step definitions
│ ├── auth_steps.go # Authentication steps
│ ├── config_steps.go # Configuration steps
│ ├── greet_steps.go # Greeting steps
│ ├── health_steps.go # Health check steps
│ ├── jwt_retention_steps.go # JWT retention steps
│ └── steps.go # Main step registration
├── suite.go # Test suite initialization
├── suite_feature.go # Feature-specific suite support
└── testserver/ # Test server implementation
├── client.go # HTTP test client
└── server.go # Test server with config
``` ```
**Correct step definition:** ## 🎯 Core Components
### 1. Test Server
**Location:** `pkg/bdd/testserver/`
The test server provides a real HTTP server instance for black-box testing:
- **Hybrid Testing**: Runs in-process (not external process)
- **Configuration**: Loads feature-specific configs from `features/*/*-test-config.yaml`
- **Database**: Manages PostgreSQL connections with proper isolation
- **Port Management**: Uses feature-specific ports (9192-9196)
**Key Functions:**
- `NewServer()` - Creates test server instance
- `Start()` - Starts server with feature-specific configuration
- `initDBConnection()` - Initializes database connection
- `createTestConfig()` - Loads feature-specific configuration
### 2. Step Definitions
**Location:** `pkg/bdd/steps/`
Step definitions implement the Gherkin scenarios using Godog:
- **Domain-Specific**: Organized by feature area (auth, config, greet, etc.)
- **Reusable**: Common patterns in `common_steps.go`
- **Exact Matching**: Uses Godog's exact regex patterns
**Example:**
```go ```go
ctx.Step(`^the response should be "{\"([^"]*)\":\"([^"]*)\"}"$`, func(arg1, arg2 string) error { // greet_steps.go
// Implementation here func (gs *GreetSteps) iRequestAGreetingFor(name string) error {
return nil return gs.client.Request("GET", fmt.Sprintf("/api/v1/greet/%s", name), nil)
}) }
``` ```
**Incorrect patterns that cause "undefined" warnings:** ### 3. Synchronization Helpers
**Location:** `pkg/bdd/helpers/`
Helpers provide robust waiting mechanisms for async operations:
- **Timeout Support**: All functions include timeout parameters
- **Polling**: Uses context-based polling with configurable intervals
- **Common Patterns**: Covers server readiness, config reload, API availability
**Available Helpers:**
- `waitForServerReady()` - Waits for server to be ready
- `waitForConfigReload()` - Detects configuration changes
- `waitForCondition()` - Generic condition waiting
- `waitForV2APIEnabled()` - Checks v2 API availability
### 4. Parallel Testing
**Location:** `pkg/bdd/parallel/`
Parallel execution infrastructure for CI/CD optimization:
- **Port Management**: `PortManager` allocates unique ports
- **Resource Monitoring**: Tracks memory, goroutines, CPU usage
- **Controlled Parallelism**: `ParallelTestRunner` limits concurrency
**Key Features:**
- Thread-safe port allocation
- Resource limit enforcement
- Timeout detection
- Comprehensive monitoring
### 5. Feature Contexts
**Location:** `pkg/bdd/context/`
Feature-specific test contexts for better organization:
- **AuthContext**: User management and authentication
- **ConfigContext**: Configuration file handling
- **Extensible**: Easy to add new feature contexts
## 🚀 Test Execution
### Running All Tests
```bash
# Default: Run all features sequentially
go test ./features/...
# With environment variables
DLC_DATABASE_HOST=localhost DLC_DATABASE_PORT=5432 \
DLC_DATABASE_USER=postgres DLC_DATABASE_PASSWORD=postgres \
DLC_DATABASE_NAME=dance_lessons_coach_bdd_test \
DLC_DATABASE_SSL_MODE=disable \
go test ./features/...
```
### Feature-Specific Testing
```bash
# Test specific feature
./scripts/test-feature.sh greet
# Test with specific tags
./scripts/test-by-tag.sh @smoke greet
```
### Parallel Testing
```bash
# Run all features in parallel
./scripts/test-all-features-parallel.sh
# Run specific features in parallel
# (Requires PostgreSQL container running)
```
### Tag-Based Testing
```bash
# List available tags
./scripts/run-bdd-tests.sh list-tags
# Run smoke tests
./scripts/run-bdd-tests.sh run @smoke
# Run critical tests for auth
./scripts/run-bdd-tests.sh run @critical @auth
```
## 📋 Test Organization
### Feature Structure
Each feature follows this structure:
```
features/{feature}/
├── {feature}.feature # Gherkin scenarios
├── {feature}-test-config.yaml # Feature-specific config
└── {feature}_test.go # Go test runner
```
### Configuration Files
Feature-specific YAML files define test environment:
```yaml
# features/greet/greet-test-config.yaml
server:
host: "127.0.0.1"
port: 9194
database:
host: "localhost"
port: 5432
name: "dance_lessons_coach_greet_test"
api:
v2_enabled: true
```
### Tagging System
Comprehensive tagging for selective test execution:
- **Feature Tags**: `@auth`, `@config`, `@greet`, `@health`, `@jwt`
- **Priority Tags**: `@smoke`, `@critical`, `@basic`, `@advanced`
- **Component Tags**: `@api`, `@v2`, `@database`, `@security`
See `features/BDD_TAGS.md` for complete documentation.
## 🔧 Database Management
### Database Creation
The framework handles database creation automatically:
1. **PostgreSQL Container**: Uses Docker (`dance-lessons-coach-postgres`)
2. **Feature Databases**: Creates `dance_lessons_coach_{feature}_test` per feature
3. **Cleanup**: Automatically drops databases after tests
**Database Creation Flow:**
1. Check if database exists
2. Create if missing (`createdb` command)
3. Run tests with isolated database
4. Cleanup (`dropdb` command)
### Configuration
Database settings come from:
- Environment variables (`DLC_DATABASE_*`)
- Feature-specific config files
- Default values for development
## 🧪 Best Practices
### Step Definition Patterns
```go ```go
// Wrong: Different regex pattern // ✅ DO: Use Godog's exact regex patterns
ctx.Step(`^the response should be "{\"message\":\"([^"]*)\"}"$`, func(message string) error { ctx.Step(`^I request a greeting for "([^"]*)"$`, sc.iRequestAGreetingFor)
// ...
})
// Wrong: Different parameter names // ❌ DON'T: Use different patterns
ctx.Step(`^the response should be "{\"([^"]*)\":\"([^"]*)\"}"$`, func(key, value string) error { ctx.Step(`^I request greeting "(.*)"$`, sc.iRequestAGreetingFor)
// ...
})
``` ```
## Current Implementation ### Test Isolation
### Step Definition Strategy - Each feature has unique port and database
- No shared state between features
- Cleanup after each test run
- Feature-specific configuration
1. **First eliminate "undefined" warnings** by using Godog's exact suggested patterns ### Synchronization
2. **Return `godog.ErrPending`** initially to confirm pattern matching works
3. **Then implement actual validation** logic
### Files ```go
// ✅ DO: Use helpers for async operations
helpers.waitForServerReady(client, 30*time.Second)
- `suite.go`: Test suite initialization and server management // ❌ DON'T: Use fixed sleep times
- `testserver/`: Test server and client implementation time.Sleep(5 * time.Second)
- `steps/`: Step definitions for each feature ```
## Debugging "Undefined" Steps ### Context Management
If you see "undefined" warnings: ```go
// ✅ DO: Use feature-specific contexts
switch featureName {
case "auth":
authCtx = context.NewAuthContext(client)
context.InitializeAuthContext(ctx, client)
}
```
1. Run the tests to see Godog's suggested pattern: ## 📈 Performance Optimization
```bash
go test ./features/... -v
```
2. Copy the **exact regex pattern** from the error message ### Parallel Execution
3. Copy the **exact parameter names** (`arg1, arg2`, etc.)
4. Update your step definition to match exactly
## Common Mistakes - Use `scripts/test-all-features-parallel.sh` for CI/CD
- Limit parallelism based on system resources
- Monitor resource usage with `ResourceMonitor`
The "undefined" warnings are **not a Godog bug** - they occur when step definitions don't match Godog's expected patterns exactly: ### Selective Testing
- Using different regex patterns than what Godog suggests - Run only relevant tests with tag filtering
- Using descriptive parameter names instead of `arg1, arg2` - Use `@smoke` for quick validation
- Not escaping quotes properly in JSON patterns - Use `@critical` for essential path testing
- Trying to be "clever" with regex optimization
**Solution**: Always use the exact pattern and parameter names that Godog suggests in its error messages. ### Resource Management
## Best Practices - Set appropriate timeouts
- Limit maximum goroutines
- Monitor memory usage
- Cleanup resources promptly
1. **Follow Godog's suggestions exactly** - Copy-paste the pattern and parameter names ## 🔧 Troubleshooting
2. **Test pattern matching first** - Use `godog.ErrPending` to verify patterns work
3. **Then implement logic** - Replace `godog.ErrPending` with actual validation
4. **Don't over-optimize regex** - Use the patterns Godog provides, even if they seem verbose
5. **One pattern per step type** - Use generic patterns to cover similar steps
## Why This Matters ### Common Issues
Godog's step matching is **very specific by design**: | Issue | Cause | Solution |
- It needs to reliably match feature file steps to code |-------|-------|----------|
- It provides exact patterns to ensure consistency | Undefined steps | Step pattern mismatch | Use Godog's exact suggested patterns |
- Following its suggestions guarantees your steps will be recognized | Port conflicts | Multiple servers | Check port allocation in config files |
| Database connection | PostgreSQL not running | Start with `docker compose up -d postgres` |
| Test isolation | Shared state | Verify unique ports/databases per feature |
**Remember**: The "undefined" warnings are Godog telling you exactly how to fix your step definitions! ### Debugging
```bash
# Verbose output
go test ./features/... -v
# Check specific feature
cd features/greet && go test -v .
# List available tags
./scripts/run-bdd-tests.sh list-tags
```
