To achieve **complete scenario isolation**, we need a **3-layer approach:**
| Layer | Component | Strategy | Status |
|-------|-----------|----------|--------|
| DB | PostgreSQL tables | Schema-per-scenario | ✅ Implemented |
| Memory | Server-level state (JWT secrets) | Reset to initial state | ✅ Implemented |
| Memory | Step-level state (tokens, user IDs) | Per-scenario state map | ✅ Implemented |
| Memory | User store | Reset/clear between scenarios | ⚠️ TODO |
| Memory | JWT secrets | Reset to initial state | ✅ Implemented |
| Memory | Auth cache | Reset/clear between scenarios | ⚠️ TODO |
| Cache | Redis/Memcached | Key prefix with schema hash | ⚠️ TODO |
### Layer 3: Per-Scenario Step State Isolation
**New insight from test failures:** Step definition structs (AuthSteps, GreetSteps, etc.) maintain state in their fields:
- `lastToken`, `firstToken` in AuthSteps
- `lastUserID` in AuthSteps
This state **spills across scenarios** even with schema isolation, because struct fields are shared across all scenarios in a test process.
**Solution:** Create a `ScenarioState` manager with per-scenario isolation:
```go
type ScenarioState struct {
LastToken string
FirstToken string
LastUserID uint
}
type scenarioStateManager struct {
mu sync.RWMutex
states map[string]*ScenarioState // keyed by scenario hash
}
// Usage in step definitions:
func (s *AuthSteps) iShouldReceiveAValidJWTToken() error {
state := steps.GetScenarioState(s.scenarioName)
state.LastToken = extractedToken
// ...
}
```
**Benefits:**
- ✅ Zero code changes to step definitions (with helper functions)
- ✅ Thread-safe (sync.RWMutex)
- ✅ Consistent state per scenario
- ✅ Automatic cleanup via BeforeScenario/AfterScenario hooks
- ✅ Works with random test order
**Status:** Implemented in `pkg/bdd/steps/scenario_state.go`

2. **Single Responsibility**: Each file focuses on a specific area of functionality
3. **Reusability**: Common steps are shared via `common_steps.go`
4. **Scalability**: Easy to add new domains as the application grows
5. **State Isolation**: Use per-scenario state to prevent pollution between test scenarios
## Adding New Steps

- Use descriptive, action-oriented names
- Follow the pattern: `i[Action][Object]` or `the[Object][State]`
- Example: `iRequestAGreetingFor`, `theAuthenticationShouldBeSuccessful`
- Use present tense for actions: "I authenticate", "the server reloads"
## State Isolation Pattern
**Problem:** Step definition structs (AuthSteps, GreetSteps, etc.) maintain state in their fields (e.g., `lastToken`, `lastUserID`). This state persists across all scenarios in a test process, causing pollution even with database schema isolation.
**Solution:** Use the `ScenarioState` manager for per-scenario state isolation.
### How It Works
The `scenario_state.go` provides a thread-safe mechanism to store and retrieve state that is isolated per scenario:
```go
// Get scenario-specific state
state := steps.GetScenarioState(scenarioName)
// Store scenario-specific data
state.LastToken = token
state.LastUserID = userID
// Retrieve scenario-specific data
token := state.LastToken
```
### Usage in Step Definitions
Instead of storing state in struct fields:
```go
// ❌ NOT RECOMMENDED - state shared across all scenarios
type AuthSteps struct {
client *testserver.Client
lastToken string // Shared across all scenarios!
lastUserID uint // Shared across all scenarios!
}
func (s *AuthSteps) iShouldReceiveAValidJWTToken() error {
s.lastToken = extractedToken // Pollutes other scenarios
return nil
}
```
Use per-scenario state:
```go
// ✅ RECOMMENDED - state isolated per scenario
type AuthSteps struct {
client *testserver.Client
scenarioName string // Track current scenario for state isolation
}
func (s *AuthSteps) iShouldReceiveAValidJWTToken() error {
state := steps.GetScenarioState(s.scenarioName)
state.LastToken = extractedToken // Isolated to this scenario
return nil
}
```
### Integration with Suite Hooks
Clear state in AfterScenario to prevent memory growth:
```go
sc.AfterScenario(func(s *godog.Scenario, err error) {
scenarioKey := s.Name
if s.Uri != "" {
scenarioKey = fmt.Sprintf("%s:%s", s.Uri, s.Name)
}
steps.ClearScenarioState(scenarioKey)
})
```
### ScenarioState Structure
The `ScenarioState` struct contains common fields needed across step definitions:
```go
type ScenarioState struct {
LastToken string
FirstToken string
LastUserID uint
// Add more fields as needed for other step types
}
```
If you need additional scenario-scoped fields, add them to the `ScenarioState` struct.
## Testing the Steps
Run BDD tests with:
```bash
# Run all features
go test ./features/... -v
# Run specific feature
go test ./features/auth -v
# Run with state tracing enabled
BDD_TRACE_STATE=1 go test ./features/auth -v
# Validate full test suite
./scripts/validate-test-suite.sh 1
```
## State Cleanup Strategy
| Cleanup Level | When | What | Implementation |
|---------------|------|------|----------------|
| Per-Scenario | After each scenario | Step struct fields | `ClearScenarioState()` |
| Per-Scenario | After each scenario | Database state | `CleanupDatabase()` (if no schema isolation) |
| Per-Scenario | After each scenario | Schema | `DROP SCHEMA` (if schema isolation enabled) |
| Per-Process | After each feature test | Server-level state | `ResetJWTSecrets()` |
| Per-Suite | After all scenarios | All state | Server restart |
## Best Practices
### 1. Use Per-Scenario State for Shared Data
Any data that:
- Is modified during scenario execution
- Affects subsequent steps in the same scenario
- Should NOT affect other scenarios
**Use:** `GetScenarioState(scenarioName).Field`
### 2. Keep Step Definitions Stateless Where Possible
If a step doesn't need to store intermediate state, don't store it:
```go
// ✅ Good - stateless
func (s *GreetSteps) iRequestAGreetingFor(name string) error {
return s.client.Request("GET", fmt.Sprintf("/api/v1/greet/%s", name), nil)
}
// ❌ Avoid - unnecessary state
func (s *GreetSteps) iRequestAGreetingFor(name string) error {
s.lastGreetedName = name // Unnecessary unless used later
return s.client.Request("GET", fmt.Sprintf("/api/v1/greet/%s", name), nil)
}
```
### 3. Prefix Config Files Per-Scenario
If your scenario modifies config files, use scenario-specific paths:
```go
configPath := fmt.Sprintf("features/%s/%s-scenario-%s.yaml",
feature, feature, scenarioKey)
```
### 4. Document Dependencies
If a step depends on state set by another step, document it:
```go
// Step: The user should have a valid JWT token
// Requires: iAuthenticateWithUsernameAndPassword to have been called first
func (s *AuthSteps) theUserShouldHaveAValidJWTToken() error {
state := steps.GetScenarioState(s.scenarioName)
if state.LastToken == "" {
return fmt.Errorf("no token found - did you authenticate first?")
}
// Verify token is valid...
}
```
## Future Domains
@@ -47,4 +208,44 @@ As the application grows, consider adding:
- `payment_steps.go` - Payment processing steps
- `notification_steps.go` - Notification and email steps
- `admin_steps.go` - Admin-specific functionality steps
- `api_steps.go` - General API interaction patterns
- `api_steps.go` - General API interaction patterns
- `user_steps.go` - User profile and management steps (if auth gets complex)
## Troubleshooting
### State Pollution Between Scenarios
**Symptom:** Tests pass individually but fail when run together
**Check:**
1. Are you using struct fields to store state? → Use `ScenarioState` instead
2. Are database tables being cleaned up? → Verify `CleanupDatabase()` or schema isolation
3. Are JWT secrets being reset? → Verify `ResetJWTSecrets()` is called
**Debug:** Enable state tracing:
```bash
BDD_TRACE_STATE=1 go test ./features/auth -v
```
### Timeout or Delay Issues
**Symptom:** Config reloading tests fail intermittently
**Cause:** Server monitors config files every 1 second
**Fix:** Add delays >1100ms after config file changes:
```go
time.Sleep(1100 * time.Millisecond) // Wait for monitoring cycle
```
### Missing Step Definitions
**Symptom:** `undefined step` error
**Check:**
1. Step is defined in the appropriate `*_steps.go` file
2. Step is registered in `steps.go`
3. Step regex matches the feature file text exactly
4. No typos in the step name
**Tip:** Run with `-v` to see which step is undefined

# BDD Test Configuration Schema
## Overview
This document describes the configuration architecture for BDD tests in the dance-lessons-coach project.
It establishes a clear hierarchy and flow of configuration parameters to ensure predictable, maintainable,
and isolated test execution.
## Configuration Sources (Priority Order)
### 1. Explicit Parameters (Highest Priority)
Passed directly between components with no hidden behavior:
- `FEATURE`: Which feature is being tested (`greet`, `config`, `auth`, `health`, `jwt`)
- `GODOG_TAGS`: Scenario tag filters (e.g., `@v2`, `~@flaky`, `~@todo`)
- `Config` struct: Passed explicitly to server initialization
### 2. Feature-Specific Configuration Files
Loaded from filesystem when testing specific features:
- Path: `features/{FEATURE}/{FEATURE}-test-config.yaml`
- Used by: Config hot-reload tests only
- Monitored by: `testserver.monitorConfigFile()`
- Example: `features/config/config-test-config.yaml`
### 3. Environment Variables (External Control Only)
Set by test scripts and CI/CD, **NOT read deep in implementation code**:
| Variable | Purpose | Default | Set By |
|----------|---------|---------|-------|
| `DLC_API_V2_ENABLED` | Enable v2 API globally | `false` | Test scripts |
| `BDD_SCHEMA_ISOLATION` | Enable per-scenario database schema isolation | `false` | Test scripts, validate-test-suite.sh |
| `BDD_ENABLE_CLEANUP_LOGS` | Enable detailed cleanup logging | `false` | Test scripts |
| `BDD_TRACE_STATE` | Enable state tracing | `false` | Test scripts |
| `FIXED_TEST_PORT` | Use fixed port instead of random | `false` | Test scripts |
| `FEATURE` | Current feature under test | `""` | testsetup.CreateTestSuite |
| `GODOG_TAGS` | Tag filter for scenario selection | `"~@flaky && ~@todo && ~@skip"` | CreateTestSuite |
### 4. Hardcoded Defaults (Fallback)
Used when no other source provides a value:
- Port: Random in range 10000-19999 (or 9191 if FIXED_TEST_PORT=true)
- JWT Secret: `test-secret-key-for-bdd-tests`
- Database: localhost:5432, postgres/postgres, dance_lessons_coach
- Logging Level: debug
- v2_enabled: false

## Use Cases
### UC-1: Default Test Run (No v2, No Config File)
```
Input: go test ./features/greet
FEATURE: greet
GODOG_TAGS: ~@flaky && ~@todo && ~@skip
Config Source: createTestConfig(port)
v2_enabled: false
Result: v1 scenarios pass, v2 scenarios skipped by tag filter
```
### UC-2: v2 API Tests (Split Test Suite)
```
Input: go test ./features/greet (with GODOG_TAGS="@v2" in v2 subtest)
FEATURE: greet
GODOG_TAGS: @v2 && ~@skip
Config Source: createTestConfig(port) with v2 check
v2_enabled: true (because FEATURE=greet AND tags contain @v2)
Result: v2 scenarios execute with v2 API available
Flow:
1. TestGreetBDD runs v1 subtest with tags="~@v2"
2. TestGreetBDD runs v2 subtest with tags="@v2"
3. Each subtest starts its own server
4. Server in v2 subtest has v2_enabled=true
5. v2 scenarios pass
```
### UC-3: Config Hot Reload Tests
```
Input: go test ./features/config
FEATURE: config
GODOG_TAGS: ~@flaky && ~@todo && ~@skip
Config File: features/config/config-test-config.yaml
Config Monitor: Watches config file for changes
When config file is modified:
1. monitorConfigFile() detects file change via mod time
2. Calls ReloadConfig()
3. ReloadConfig() for FEATURE=config: loads from config file
4. Server restarts with new config
5. Subsequent scenarios see new configuration
Note: This is the ONLY feature that uses config file hot-reload.
All other features use hardcoded/test defaults.
```
### UC-4: Config Hot Reload with v2 Enable
```
Scenario: Hot reloading feature flags
Steps:
1. Server starts with default config (v2_enabled: false)
2. Test sets v2_enabled: true in config file
3. Config monitor detects change
4. ReloadConfig() called
5. Server loads from config file (NOT createTestConfig)
6. Server restarts with v2_enabled: true
7. Test verifies v2 API works
Current Bug: ReloadConfig() calls createTestConfig() which:
- Reads FEATURE=config
- Reads GODOG_TAGS (doesn't contain @v2)
- Sets v2_enabled: false
- Overrides the config file setting!
Fix: ReloadConfig() must load from file for config feature.
```
## Implementation Details
### Config Creation Flow
```go
// pkg/bdd/testserver/server.go
func NewServer() *Server {
port := getRandomPort() // 10000-19999
return &Server{port: port}
}
func (s *Server) Start() error {
cfg := createTestConfig(s.port)
// ... start server with cfg
go s.monitorConfigFile()
}
// CURRENT - BAD
func createTestConfig(port int) *config.Config {
feature := os.Getenv("FEATURE")
tags := os.Getenv("GODOG_TAGS")
enableV2 := false
if feature == "greet" && strings.Contains(tags, "@v2") {
enableV2 = true
}
// ...
return &config.Config{
API: config.APIConfig{V2Enabled: enableV2},
// ...
}
}
// PROPOSED - GOOD
func createTestConfig(port int, opts ConfigOptions) *config.Config {
defaults := &config.Config{
Server: config.ServerConfig{Host: "0.0.0.0", Port: port},
// ... all hardcoded defaults
}
// Apply explicit options (passed from caller)
if opts.V2Enabled {
defaults.API.V2Enabled = true
}
return defaults
}
// ConfigOptions passed from testsuite
type ConfigOptions struct {
V2Enabled bool
UseConfigFile bool
ConfigFilePath string
}
```
### Reload Flow Fix
```go
// pkg/bdd/testserver/server.go
func (s *Server) ReloadConfig() error {
feature := os.Getenv("FEATURE")
if feature == "config" && s.configFilePath != "" {
// For config tests: load from monitored file
cfg, err := loadConfigFromFile(s.configFilePath)
if err != nil {
return err
}
return s.applyConfig(cfg)
}
// For all other features: use defaults
// (hot reload not supported for non-config features)
cfg := createDefaultConfig(s.port)
return s.applyConfig(cfg)
}
func loadConfigFromFile(path string) (*config.Config, error) {
v := viper.New()
v.SetConfigFile(path)
v.SetConfigType("yaml")
if err := v.ReadInConfig(); err != nil {
return nil, err
}
var cfg config.Config
if err := v.Unmarshal(&cfg); err != nil {
return nil, err
}
// Apply hardcoded values that should NOT come from file
// (database connection for BDD tests, etc.)
cfg.Database.Host = getDatabaseHost()
cfg.Database.Port = getDatabasePort()
cfg.Database.User = "postgres"
cfg.Database.Password = "postgres"
cfg.Database.Name = "dance_lessons_coach"
return &cfg, nil
}
```
## Configuration File Format
### Config Test File (features/config/config-test-config.yaml)
```yaml
server:
host: "127.0.0.1"
port: 9191
logging:
level: "info"
json: false
api:
v2_enabled: false # Will be toggled by tests
telemetry:
enabled: true
sampler:
type: "parentbased_always_on"
ratio: 1.0
auth:
jwt:
ttl: 1h
database:
# These are OVERRIDDEN by BDD test infrastructure
host: "localhost"
port: 5432
user: "postgres"
password: "postgres"
name: "dance_lessons_coach_bdd_test"
ssl_mode: "disable"
```
## State Isolation
### Per-Scenario State
- Managed by: `pkg/bdd/steps/scenario_state.go`
- Key: SHA256 hash of scenario URI + name
- State includes: LastToken, FirstToken, LastUserID, LastSecret, LastError
- Cleared: At start of each scenario in BeforeScenario hook
### Database Schema Isolation
- Enabled by: `BDD_SCHEMA_ISOLATION=true`
- Mechanism: Creates unique schema per scenario
- Schema name: `test_{sha256(scenarioKey)[:8]}`
- Search path: Set via `SET search_path TO ...`
- Cleanup: Schema dropped after scenario
### Server-Level State Reset
- JWT secrets: Reset after every scenario via `ResetJWTSecrets()`
- Database: Cleaned up after every scenario
- Auth state: Per-scenario via state manager
## Package Responsibilities
### pkg/bdd/testserver
- **Purpose**: Test HTTP server management
- **Responsibilities**:
- Server lifecycle (Start, Stop)
- Configuration loading and reloading
- Database cleanup
- Schema isolation
- JWT secret management
- Config file monitoring (config feature only)
### pkg/bdd/testsetup
- **Purpose**: Godog test suite setup
- **Responsibilities**:
- Feature test file discovery
- Test suite configuration
- Tag filtering
- godog options setup
### pkg/bdd/suite
- **Purpose**: Test suite initialization hooks
- **Responsibilities**:
- BeforeSuite/AfterSuite hooks
- BeforeScenario/AfterScenario hooks
- Step context creation
- State isolation setup
### pkg/bdd/steps
- **Purpose**: Step definitions
- **Responsibilities**:
- All Gherkin step implementations
- Per-scenario state management
- Per-feature step organization
## Migration Plan
### Phase 1: Fix Config Reload (Urgent)
1. Create `loadConfigFromFile()` function
2. Modify `ReloadConfig()` to use file for config feature
3. Add tests to verify config hot-reload works
### Phase 2: Clean Up Config Creation
1. Create `ConfigOptions` struct
2. Modify `createTestConfig()` to accept options
3. Update callers to pass explicit options
4. Remove env var reading from deep in config creation
### Phase 3: Document and Validate
1. Write comprehensive documentation (this file)
2. Add validation tests for all use cases
3. Create troubleshooting guide
### Phase 4: Consider Package Merge (Optional)
1. Evaluate merging testserver + testsetup
2. Design new `pkg/bdd/testing` package structure
3. Migrate code incrementally
## Rules for Adding New Configuration
1. **Prefer explicit parameters** over environment variables
2. **Read env vars at ONE layer only** (typically test entry point)
3. **Document all config sources** in this file
4. **Test config combinations** to prevent override bugs
5. **Never read env vars in hot paths** (scenario steps, server handlers)
## Troubleshooting
### Symptom: Config file changes not applied
- Check: Is FEATURE=config?
- Check: Does config file exist at `features/config/config-test-config.yaml`?
- Check: Does monitorConfigFile() detect the change?
- Fix: ReloadConfig() must load from file, not createTestConfig()
### Symptom: v2 tests fail with 404
- Check: Is FEATURE=greet?
- Check: Does GODOG_TAGS contain @v2?
- Check: Does createTestConfig() see the tags?
- Fix: Ensure tags are set before server creation
### Symptom: State pollution between scenarios
- Check: Is schema isolation enabled?
- Check: Are step definitions using per-scenario state?
- Fix: Use ScenarioState for all mutable state
