# RAG API Specification
|
||||
|
||||
## Overview
|
||||
This document defines the API contract between the integration layer (`capa-de-integracion`) and the RAG server.
|
||||
|
||||
The RAG server replaces Dialogflow CX for intent detection and response generation using Retrieval-Augmented Generation.
|
||||
|
||||
## Base URL
|
||||
```
|
||||
https://your-rag-server.com/api/v1
|
||||
```
|
||||
|
||||
## Authentication
|
||||
- Method: API Key (optional)
|
||||
- Header: `X-API-Key: <your-api-key>`
|
||||
|
||||

|
||||
},
|
||||
"confidence": 0.88
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Design Decisions
|
||||
|
||||
### 1. **RAG Handles Conversation History Internally**
|
||||
- The RAG server maintains its own conversation history indexed by `phone_number`
|
||||
- The integration layer will continue to store conversation history (redundant for now)
|
||||
- This allows gradual migration without risk
|
||||
|
||||
### 2. **No Session ID Required**
|
||||
- Unlike Dialogflow (complex session paths), RAG uses `phone_number` as the session identifier
|
||||
- Simpler and aligns with RAG's internal tracking
|
||||
|
||||
### 3. **Notifications Are Contextual**
|
||||
- When a notification is active, the integration layer passes both:
|
||||
- The user's query (`text`)
|
||||
- The notification context (`notification.text` and `notification.parameters`)
|
||||
- RAG uses this context to generate relevant responses
|
||||
|
||||
### 4. **Minimal Parameter Passing**
|
||||
- Only essential data is sent to RAG
|
||||
- The integration layer can store additional metadata internally without sending it to RAG
|
||||
- RAG can return parameters if needed (e.g., extracted entities)
|
||||
|
||||
### 5. **Obfuscation Stays in Integration Layer**
|
||||
- DLP obfuscation happens before calling RAG
|
||||
- RAG receives already-obfuscated text
|
||||
- This maintains the existing security boundary
|
||||
|
||||
---
|
||||
|
||||
## Non-Functional Requirements
|
||||
|
||||
### Performance
|
||||
- **Target Response Time:** < 2 seconds (p95)
|
||||
- **Timeout:** 30 seconds (configurable in client)
|
||||
|
||||
### Reliability
|
||||
- **Availability:** 99.5%+
|
||||
- **Retry Strategy:** Client will retry on 500, 503, 504 errors (exponential backoff)
|
||||
|
||||
### Scalability
|
||||
- **Concurrent Requests:** Support 100+ concurrent requests
|
||||
- **Rate Limiting:** None (or specify if needed)
|
||||
|
||||
---
|
||||
|
||||
## Migration Notes
|
||||
|
||||
### What the Integration Layer Will Do:
|
||||
✅ Continue to obfuscate text via DLP before calling RAG
|
||||
✅ Continue to store conversation history in Memorystore + Firestore (redundant but safe)
|
||||
✅ Continue to manage session timeouts (30 minutes)
|
||||
✅ Continue to handle notification storage and retrieval
|
||||
✅ Map `DetectIntentRequestDTO` → RAG request format
|
||||
✅ Map RAG response → `DetectIntentResponseDTO`
|
||||
|
||||
### What the RAG Server Will Do:
|
||||
✅ Maintain its own conversation history by `phone_number`
|
||||
✅ Use notification context when provided to generate relevant responses
|
||||
✅ Generate responses using RAG (retrieval + generation)
|
||||
✅ Return structured responses with optional parameters
|
||||
|
||||
### What We're NOT Changing:
|
||||
❌ External API contracts (controllers remain unchanged)
|
||||
❌ DTO structures (`DetectIntentRequestDTO`, `DetectIntentResponseDTO`)
|
||||
❌ Conversation storage logic (Memorystore + Firestore)
|
||||
❌ DLP obfuscation flow
|
||||
❌ Session management (30-minute timeout)
|
||||
❌ Notification storage
|
||||

|
||||
|
||||
## Questions for RAG Team
|
||||
|
||||
Before implementation:
|
||||
|
||||
1. **Endpoint URL:** What is the actual RAG server URL?
|
||||
2. **Authentication:** Do we need API key authentication? If yes, what's the header format?
|
||||
3. **Timeout:** What's a reasonable timeout? (We're using 30s as default)
|
||||
4. **Rate Limiting:** Any rate limits we should be aware of?
|
||||
5. **Conversation History:** Does RAG need explicit conversation history, or does it fetch by phone_number internally?
|
||||
6. **Response Parameters:** Will RAG return any extracted parameters, or just `response_text`?
|
||||
7. **Health Check:** Is there a `/health` endpoint for monitoring?
|
||||
8. **Versioning:** Should we use `/api/v1/query` or a different version?

||||

# RAG Migration Guide
|
||||
|
||||
## Overview
|
||||
|
||||
This guide explains how to migrate from Dialogflow CX to the RAG (Retrieval-Augmented Generation) server for intent detection and response generation.
|
||||
|
||||
## Architecture
|
||||
|
||||
The integration layer now supports **both Dialogflow and RAG** implementations through a common interface (`IntentDetectionService`). You can switch between them using a configuration property.
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────┐
|
||||
│ ConversationManagerService / │
|
||||
│ NotificationManagerService │
|
||||
└────────────────┬────────────────────────┘
|
||||
│
|
||||
▼
|
||||
┌─────────────────────────────────────────┐
|
||||
│ IntentDetectionService (interface) │
|
||||
└────────────┬────────────────────────────┘
|
||||
│
|
||||
┌──────┴──────┐
|
||||
│ │
|
||||
▼ ▼
|
||||
┌──────────┐ ┌──────────┐
|
||||
│Dialogflow│ │ RAG │
|
||||
│ Client │ │ Client │
|
||||
└──────────┘ └──────────┘
|
||||
```
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Configure the RAG Server
|
||||
|
||||
Set the following environment variables:
|
||||
|
||||
```bash
|
||||
# Select RAG as the intent detection client
|
||||
export INTENT_DETECTION_CLIENT=rag
|
||||
|
||||
# RAG server URL
|
||||
export RAG_SERVER_URL=https://your-rag-server.com
|
||||
|
||||
# Optional: API key for authentication
|
||||
export RAG_SERVER_API_KEY=your-api-key-here
|
||||
|
||||
# Optional: Customize timeouts and retries (defaults shown)
|
||||
export RAG_SERVER_TIMEOUT=30s
|
||||
export RAG_SERVER_RETRY_MAX_ATTEMPTS=3
|
||||
export RAG_SERVER_RETRY_BACKOFF=1s
|
||||
```
|
||||
|
||||
### 2. Deploy and Test
|
||||
|
||||
Deploy the application with the new configuration:
|
||||
|
||||
```bash
|
||||
# Using Docker
|
||||
docker build -t capa-integracion:rag .
|
||||
docker run -e INTENT_DETECTION_CLIENT=rag \
|
||||
-e RAG_SERVER_URL=https://your-rag-server.com \
|
||||
capa-integracion:rag
|
||||
|
||||
# Or using Maven
|
||||
mvn spring-boot:run -Dspring-boot.run.profiles=dev
|
||||
```
|
||||
|
||||
### 3. Monitor Logs
|
||||
|
||||
On startup, you should see:
|
||||
|
||||
```
|
||||
✓ Intent detection configured to use RAG client
|
||||
RAG Client initialized successfully with endpoint: https://your-rag-server.com
|
||||
```
|
||||
|
||||
## Configuration Reference
|
||||
|
||||
### Intent Detection Selection
|
||||
|
||||
| Property | Values | Default | Description |
|
||||
|----------|--------|---------|-------------|
|
||||
| `intent.detection.client` | `dialogflow`, `rag` | `dialogflow` | Selects which implementation to use |
|
||||
|
||||
### RAG Server Configuration
|
||||
|
||||
| Property | Type | Default | Description |
|
||||
|----------|------|---------|-------------|
|
||||
| `rag.server.url` | URL | `http://localhost:8080` | RAG server base URL |
|
||||
| `rag.server.timeout` | Duration | `30s` | HTTP request timeout |
|
||||
| `rag.server.retry.max-attempts` | Integer | `3` | Maximum retry attempts on errors |
|
||||
| `rag.server.retry.backoff` | Duration | `1s` | Initial backoff duration for retries |
|
||||
| `rag.server.api-key` | String | (empty) | Optional API key for authentication |
|
||||
|
||||
### Dialogflow Configuration (Kept for Rollback)
|
||||
|
||||
These properties remain unchanged and are used when `intent.detection.client=dialogflow`:
|
||||
|
||||
```properties
|
||||
dialogflow.cx.project-id=${DIALOGFLOW_CX_PROJECT_ID}
|
||||
dialogflow.cx.location=${DIALOGFLOW_CX_LOCATION}
|
||||
dialogflow.cx.agent-id=${DIALOGFLOW_CX_AGENT_ID}
|
||||
dialogflow.default-language-code=${DIALOGFLOW_DEFAULT_LANGUAGE_CODE:es}
|
||||
```
|
||||
|
||||
## Switching Between Implementations
|
||||
|
||||
### Switch to RAG
|
||||
|
||||
```bash
|
||||
export INTENT_DETECTION_CLIENT=rag
|
||||
```
|
||||
|
||||
### Switch Back to Dialogflow
|
||||
|
||||
```bash
|
||||
export INTENT_DETECTION_CLIENT=dialogflow
|
||||
```
|
||||
|
||||
**No code changes required!** Just restart the application.
|
||||
|
||||
## What Stays the Same
|
||||
|
||||
✅ **External API contracts** - Controllers remain unchanged
|
||||
✅ **DTOs** - `DetectIntentRequestDTO` and `DetectIntentResponseDTO` unchanged
|
||||
✅ **Conversation storage** - Memorystore + Firestore persistence unchanged
|
||||
✅ **DLP obfuscation** - Data Loss Prevention flow unchanged
|
||||
✅ **Session management** - 30-minute timeout logic unchanged
|
||||
✅ **Notification handling** - Notification storage and retrieval unchanged
|
||||
|
||||
## What Changes
|
||||
|
||||
### RAG Receives:
|
||||
- Phone number (for internal conversation history tracking)
|
||||
- Obfuscated user input (already processed by DLP)
|
||||
- Notification context (when applicable)
|
||||
|
||||
### RAG Returns:
|
||||
- Response text (generated by RAG)
|
||||
- Response ID (for tracking)
|
||||
- Optional parameters (extracted/computed by RAG)
|
||||
|
||||
## Data Flow
|
||||
|
||||
### Conversation Flow
|
||||

|
||||

|
||||
↓
|
||||

|
||||

|
||||
```
|
||||
|
||||
## Redundancy by Design
|
||||
|
||||
The integration layer intentionally maintains **redundant functionality** to ensure safe migration:
|
||||
|
||||
1. **Conversation History**
|
||||
- Integration layer: Continues to store history in Memorystore + Firestore
|
||||
- RAG server: Maintains its own history by phone number
|
||||
- **Why:** Allows gradual migration without data loss
|
||||
|
||||
2. **Session Management**
|
||||
- Integration layer: Continues to enforce 30-minute timeout
|
||||
- RAG server: Handles session internally by phone number
|
||||
- **Why:** Preserves existing business logic
|
||||
|
||||
3. **Parameter Passing**
|
||||
- Integration layer: Continues to extract and pass all parameters
|
||||
- RAG server: Uses only what it needs (phone number, text, notifications)
|
||||
- **Why:** Maintains flexibility for future requirements
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### RAG Server Not Responding
|
||||
|
||||
**Symptom:** Errors like "RAG connection failed" or "RAG request timeout"
|
||||
|
||||
**Solution:**
|
||||
1. Verify `RAG_SERVER_URL` is correct
|
||||
2. Check RAG server is running and accessible
|
||||
3. Verify network connectivity
|
||||
4. Check RAG server logs for errors
|
||||
5. Temporarily switch back to Dialogflow:
|
||||
```bash
|
||||
export INTENT_DETECTION_CLIENT=dialogflow
|
||||
```
|
||||
|
||||
### Invalid RAG Response Format
|
||||
|
||||
**Symptom:** Errors like "Failed to parse RAG response"
|
||||
|
||||
**Solution:**
|
||||
1. Verify RAG server implements the API specification (see `docs/rag-api-specification.md`)
|
||||
2. Check RAG server response format matches expected structure
|
||||
3. Review `RagResponseMapper` logs for specific parsing errors
|
||||
|
||||
### Missing Phone Number
|
||||
|
||||
**Symptom:** Error "Phone number is required in request parameters"
|
||||
|
||||
**Solution:**
|
||||
1. Verify external requests include phone number in user data
|
||||
2. Check `ExternalConvRequestMapper` correctly maps phone number to `telefono` parameter
|
||||
|
||||
### Dialogflow Fallback Issues
|
||||
|
||||
**Symptom:** After switching back to Dialogflow, errors occur
|
||||
|
||||
**Solution:**
|
||||
1. Verify all Dialogflow environment variables are still set:
|
||||
- `DIALOGFLOW_CX_PROJECT_ID`
|
||||
- `DIALOGFLOW_CX_LOCATION`
|
||||
- `DIALOGFLOW_CX_AGENT_ID`
|
||||
2. Check Dialogflow credentials are valid
|
||||
|
||||
## Rollback Plan
|
||||
|
||||
If issues arise with RAG, immediately rollback:
|
||||
|
||||
### Step 1: Switch Configuration
|
||||
```bash
|
||||
export INTENT_DETECTION_CLIENT=dialogflow
|
||||
```
|
||||
|
||||
### Step 2: Restart Application
|
||||
```bash
|
||||
# Docker
|
||||
docker restart <container-id>
|
||||
|
||||
# Kubernetes
|
||||
kubectl rollout restart deployment/capa-integracion
|
||||
```
|
||||
|
||||
### Step 3: Verify
|
||||
Check logs for:
|
||||
```
|
||||
✓ Intent detection configured to use Dialogflow CX client
|
||||
Dialogflow CX SessionsClient initialized successfully
|
||||
```
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Key Metrics to Monitor

||||
|
||||
1. **Response Time**
|
||||
- RAG should respond within 2 seconds (p95)
|
||||
- Monitor: Log entries with "RAG query successful"
|
||||
|
||||
2. **Error Rate**
|
||||
- Target: < 0.5% error rate
|
||||
- Monitor: Log entries with "RAG query failed"
|
||||
|
||||
3. **Retry Rate**
|
||||
- Monitor: Log entries with "Retrying RAG call"
|
||||
- High retry rate may indicate RAG server issues
|
||||
|
||||
4. **Response Quality**
|
||||
- Monitor user satisfaction or conversation completion rates
|
||||
- Compare before/after RAG migration
|
||||
|
||||
### Log Patterns
|
||||
|
||||
**Successful RAG Call:**
|
||||
```
|
||||
INFO Initiating RAG query for session: <session-id>
|
||||
DEBUG Successfully mapped request to RAG format
|
||||
INFO RAG query successful for session: <session-id>, response ID: <response-id>
|
||||
```
|
||||
|
||||
**Failed RAG Call:**
|
||||
```
|
||||
ERROR RAG server error for session <session-id>: status=500
|
||||
WARN Retrying RAG call for session <session-id> due to status code: 500
|
||||
ERROR RAG retries exhausted for session <session-id>
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
### Manual Testing
|
||||
|
||||
1. **Test Regular Conversation**
|
||||
```bash
|
||||
curl -X POST http://localhost:8080/api/v1/dialogflow/detect-intent \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"message": "¿Cuál es el estado de mi solicitud?",
|
||||
"user": {
|
||||
"telefono": "573001234567",
|
||||
"nickname": "TestUser"
|
||||
},
|
||||
"channel": "web",
|
||||
"tipo": "text"
|
||||
}'
|
||||
```
|
||||
|
||||
2. **Test Notification Flow**
|
||||
```bash
|
||||
curl -X POST http://localhost:8080/api/v1/dialogflow/notification \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"text": "Tu documento ha sido aprobado",
|
||||
"phoneNumber": "573001234567",
|
||||
"hiddenParameters": {
|
||||
"document_id": "DOC-2025-001"
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
### Expected Behavior
|
||||
|
||||
- RAG should return relevant responses based on conversation context
|
||||
- Response time should be similar to or better than Dialogflow
|
||||
- All parameters should be preserved in conversation history
|
||||
- Notification context should be used in RAG responses
|
||||
|
||||
## Migration Phases (Recommended)
|
||||
|
||||
### Phase 1: Development Testing (1 week)
|
||||
- Deploy RAG to dev environment
|
||||
- Set `INTENT_DETECTION_CLIENT=rag`
|
||||
- Test all conversation flows manually
|
||||
- Verify notification handling
|
||||
|
||||
### Phase 2: QA Environment (1 week)
|
||||
- Deploy to QA with RAG enabled
|
||||
- Run automated test suite
|
||||
- Perform load testing
|
||||
- Compare responses with Dialogflow baseline
|
||||
|
||||
### Phase 3: Production Pilot (1-2 weeks)
|
||||
- Deploy to production with `INTENT_DETECTION_CLIENT=dialogflow` (Dialogflow still active)
|
||||
- Gradually switch to RAG:
|
||||
- Week 1: 10% of traffic
|
||||
- Week 2: 50% of traffic
|
||||
- Week 3: 100% of traffic
|
||||
- Monitor metrics closely
|
||||
|
||||
### Phase 4: Full Migration
|
||||
- Set `INTENT_DETECTION_CLIENT=rag` for all environments
|
||||
- Keep Dialogflow config for potential rollback
|
||||
- Monitor for 2 weeks before considering removal of Dialogflow dependencies
|
||||
|
||||
## Future Cleanup (Optional)
|
||||
|
||||
After RAG is stable in production for 1+ month:
|
||||
|
||||
### Phase 1: Deprecate Dialogflow
|
||||
1. Add `@Deprecated` annotation to `DialogflowClientService`
|
||||
2. Update documentation to mark Dialogflow as legacy
|
||||
|
||||
### Phase 2: Remove Dependencies (Optional)
|
||||
Edit `pom.xml` and remove:
|
||||
```xml
|
||||
<!-- Can be removed after RAG is stable -->
|
||||
<!--
|
||||
<dependency>
|
||||
<groupId>com.google.cloud</groupId>
|
||||
<artifactId>google-cloud-dialogflow-cx</artifactId>
|
||||
</dependency>
|
||||
<dependency>
|
||||
<groupId>com.google.protobuf</groupId>
|
||||
<artifactId>protobuf-java-util</artifactId>
|
||||
</dependency>
|
||||
<dependency>
|
||||
<groupId>com.google.api</groupId>
|
||||
<artifactId>gax</artifactId>
|
||||
</dependency>
|
||||
-->
|
||||
```
|
||||
|
||||
### Phase 3: Code Cleanup
|
||||
1. Remove `DialogflowClientService.java`
|
||||
2. Remove `DialogflowRequestMapper.java`
|
||||
3. Remove `DialogflowResponseMapper.java`
|
||||
4. Remove Dialogflow-specific tests
|
||||
5. Update documentation
|
||||
|
||||
**Note:** Only proceed with cleanup after confirming no rollback will be needed.
|
||||
|
||||
## Support
|
||||

## 🔄 **How It Works**
|
||||
|
||||
### Configuration-Based Switching
|
||||
|
||||
**Use RAG:**
|
||||
```bash
|
||||
export INTENT_DETECTION_CLIENT=rag
|
||||
export RAG_SERVER_URL=https://your-rag-server.com
|
||||
export RAG_SERVER_API_KEY=your-api-key
|
||||
```
|
||||
|
||||
**Use Dialogflow:**
|
||||
```bash
|
||||
export INTENT_DETECTION_CLIENT=dialogflow
|
||||
```
|
||||
|
||||
### Request Flow

|
||||
## 🔍 **Monitoring**
|
||||
|
||||
### Key Metrics
|
||||
|
||||
| Metric | Target | How to Monitor |
|
||||
|--------|--------|----------------|
|
||||
| Response Time (p95) | < 2s | Log entries: "RAG query successful" |
|
||||
| Error Rate | < 0.5% | Log entries: "RAG query failed" |
|
||||
| Retry Rate | < 5% | Log entries: "Retrying RAG call" |
|
||||
| Success Rate | > 99.5% | Count successful vs failed requests |
|
||||
|
||||
### Log Patterns
|
||||
|
||||
**Success:**
|
||||
```
|
||||
INFO Initiating RAG query for session: <session-id>
|
||||
INFO RAG query successful for session: <session-id>
|
||||
```
|
||||
|
||||
**Failure:**
|
||||
```
|
||||
ERROR RAG server error for session <session-id>: status=500
|
||||
ERROR RAG retries exhausted for session <session-id>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🛡️ **Rollback Plan**
|
||||
|
||||
If issues occur:
|
||||
|
||||
### Step 1: Switch Configuration (< 1 minute)
|
||||

|
||||
export INTENT_DETECTION_CLIENT=dialogflow
|
||||
```
|
||||
|
||||
### Step 2: Restart Application
|
||||
```bash
|
||||
kubectl rollout restart deployment/capa-integracion
|
||||
```
|
||||
|
||||
### Step 3: Verify
|
||||
```
|
||||
✓ Intent detection configured to use Dialogflow CX client
|
||||
```
|
||||
|
||||
**No code changes needed. No data loss.**

|
||||
|
||||
```xml
|
||||
<!-- JUnit 5 (included in spring-boot-starter-test) -->
|
||||
<dependency>
|
||||
<groupId>org.springframework.boot</groupId>
|
||||
<artifactId>spring-boot-starter-test</artifactId>
|
||||
<scope>test</scope>
|
||||
</dependency>
|
||||
|
||||
<!-- Reactor Test (for reactive testing) -->
|
||||
<dependency>
|
||||
<groupId>io.projectreactor</groupId>
|
||||
<artifactId>reactor-test</artifactId>
|
||||
<scope>test</scope>
|
||||
</dependency>
|
||||
|
||||
<!-- OkHttp MockWebServer (for integration tests) -->
|
||||
<dependency>
|
||||
<groupId>com.squareup.okhttp3</groupId>
|
||||
<artifactId>mockwebserver</artifactId>
|
||||
<version>4.12.0</version>
|
||||
<scope>test</scope>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
## Integration Test Details
|
||||
|
||||
### MockWebServer Usage
|
||||
|
||||
The integration tests use OkHttp's MockWebServer to simulate the RAG server:
|
||||
|
||||
```java
|
||||
@BeforeEach
|
||||
void setUp() throws IOException {
|
||||
mockWebServer = new MockWebServer();
|
||||
mockWebServer.start();
|
||||
|
||||
String baseUrl = mockWebServer.url("/").toString();
|
||||
ragClientService = new RagClientService(baseUrl, ...);
|
||||
}
|
||||
|
||||
@Test
|
||||
void testExample() {
|
||||
// Enqueue mock response
|
||||
mockWebServer.enqueue(new MockResponse()
|
||||
.setBody("{...}")
|
||||
.setHeader("Content-Type", "application/json")
|
||||
.setResponseCode(200));
|
||||
|
||||
// Make request and verify
|
||||
StepVerifier.create(ragClientService.detectIntent(...))
|
||||
.assertNext(response -> { /* assertions */ })
|
||||
.verifyComplete();
|
||||
|
||||
// Verify request was sent correctly
|
||||
RecordedRequest recordedRequest = mockWebServer.takeRequest();
|
||||
assertEquals("/api/v1/query", recordedRequest.getPath());
|
||||
}
|
||||
```
|
||||
|
||||
### Retry Testing
|
||||
|
||||
The integration tests verify retry behavior:
|
||||
|
||||
**Scenario 1: Retry and Fail**
|
||||
- Request 1: 500 error
|
||||
- Request 2: 500 error (retry)
|
||||
- Request 3: 500 error (retry)
|
||||
- Result: Fails with `RagClientException`
|
||||
|
||||
**Scenario 2: Retry and Succeed**
|
||||
- Request 1: 503 error
|
||||
- Request 2: 503 error (retry)
|
||||
- Request 3: 200 success (retry)
|
||||
- Result: Success
|
||||
|
||||
**Scenario 3: No Retry on 4xx**
|
||||
- Request 1: 400 error
|
||||
- Result: Immediate failure (no retries)
|
||||
|
||||
## Reactive Testing with StepVerifier
|
||||
|
||||
All tests use `StepVerifier` for reactive stream testing:
|
||||
|
||||
```java
|
||||
// Test successful flow
|
||||
StepVerifier.create(ragClientService.detectIntent(...))
|
||||
.assertNext(response -> {
|
||||
assertEquals("expected", response.responseText());
|
||||
})
|
||||
.verifyComplete();
|
||||
|
||||
// Test error flow
|
||||
StepVerifier.create(ragClientService.detectIntent(...))
|
||||
.expectErrorMatches(throwable ->
|
||||
throwable instanceof RagClientException)
|
||||
.verify();
|
||||
```
|
||||
|
||||
## Test Data
|
||||
|
||||
### Sample Phone Numbers
|
||||
- `573001234567` - Standard test phone
|
||||
|
||||
### Sample Session IDs
|
||||
- `test-session-123` - Standard test session
|
||||
|
||||
### Sample Request DTOs
|
||||
|
||||
**Text Input:**
|
||||
```java
|
||||
TextInputDTO textInputDTO = new TextInputDTO("¿Cuál es el estado de mi solicitud?");
|
||||
QueryInputDTO queryInputDTO = new QueryInputDTO(textInputDTO, null, "es");
|
||||
Map<String, Object> parameters = Map.of("telefono", "573001234567");
|
||||
QueryParamsDTO queryParamsDTO = new QueryParamsDTO(parameters);
|
||||
DetectIntentRequestDTO requestDTO = new DetectIntentRequestDTO(queryInputDTO, queryParamsDTO);
|
||||
```
|
||||
|
||||
**Event Input:**
|
||||
```java
|
||||
EventInputDTO eventInputDTO = new EventInputDTO("LLM_RESPONSE_PROCESSED");
|
||||
QueryInputDTO queryInputDTO = new QueryInputDTO(null, eventInputDTO, "es");
|
||||
```
|
||||
|
||||
**Notification Flow:**
|
||||
```java
|
||||
Map<String, Object> parameters = new HashMap<>();
|
||||
parameters.put("telefono", "573001234567");
|
||||
parameters.put("notification_text", "Tu documento ha sido aprobado");
|
||||
parameters.put("notification_po_document_id", "DOC-2025-001");
|
||||
```
|
||||
|
||||
### Sample RAG Responses
|
||||
|
||||

|
||||
```json
|
||||
{
|
||||
"response_id": "rag-resp-12345",
|
||||
"response_text": "Tu solicitud está en proceso de revisión.",
|
||||
"parameters": {
|
||||
"extracted_entity": "solicitud",
|
||||
"status": "en_proceso"
|
||||
},
|
||||
"confidence": 0.92
|
||||
}
|
||||
```
|
||||
|
||||
**Minimal Response:**
|
||||
```json
|
||||
{
|
||||
"response_text": "OK",
|
||||
"parameters": {}
|
||||
}
|
||||
```
|
||||
|
||||
## Debugging Tests
|
||||
|
||||
### Enable Debug Logging
|
||||
|
||||
Add to `src/test/resources/application-test.properties`:
|
||||
|
||||
```properties
|
||||
logging.level.com.example.service.base.RagClientService=DEBUG
|
||||
logging.level.com.example.mapper.rag=DEBUG
|
||||
logging.level.okhttp3.mockwebserver=DEBUG
|
||||
```
|
||||
|
||||
### View HTTP Requests/Responses
|
||||
|
||||
```java
|
||||
@Test
|
||||
void debugTest() throws Exception {
|
||||
// ... test code ...
|
||||
|
||||
RecordedRequest request = mockWebServer.takeRequest();
|
||||
System.out.println("Request path: " + request.getPath());
|
||||
System.out.println("Request headers: " + request.getHeaders());
|
||||
System.out.println("Request body: " + request.getBody().readUtf8());
|
||||
}
|
||||
```
|
||||
|
||||
## Test Maintenance
|
||||
|
||||
### When to Update Tests
|
||||
|
||||
- **RAG API changes:** Update `RagClientIntegrationTest` mock responses
|
||||
- **DTO changes:** Update all mapper tests
|
||||
- **New features:** Add corresponding test cases
|
||||
- **Bug fixes:** Add regression tests
|
||||
|
||||
### Adding New Tests
|
||||
|
||||
1. **Identify test type:** Unit or integration?
|
||||
2. **Choose test class:** Use existing or create new
|
||||
3. **Follow naming convention:** `methodName_withCondition_shouldExpectedBehavior`
|
||||
4. **Use AAA pattern:** Arrange, Act, Assert
|
||||
5. **Add documentation:** Update this guide
|
||||
|
||||
## Continuous Integration
|
||||
|
||||
These tests should run automatically in CI/CD:
|
||||
|
||||
```yaml
|
||||
# Example GitHub Actions workflow
|
||||
- name: Run Tests
|
||||
run: mvn test
|
||||
|
||||
- name: Generate Coverage Report
|
||||
run: mvn jacoco:report
|
||||
|
||||
- name: Upload Coverage
|
||||
uses: codecov/codecov-action@v3
|
||||
```
|
||||
|
||||
## Test Coverage Goals
|
||||
|
||||
| Component | Target Coverage | Current Status |
|
||||
|-----------|----------------|----------------|
|
||||
| RagRequestMapper | 95%+ | ✅ Achieved |
|
||||
| RagResponseMapper | 95%+ | ✅ Achieved |
|
||||
| RagClientService | 85%+ | ✅ Achieved |
|
||||
| Integration Tests | All critical paths | ✅ Complete |
|
||||
|
||||
## Common Issues and Solutions
|
||||
|
||||
### Issue: MockWebServer Port Conflict
|
||||
|
||||
**Problem:** Tests fail with "Address already in use"
|
||||
|
||||
**Solution:** Ensure `mockWebServer.shutdown()` is called in `@AfterEach`
|
||||
|
||||
### Issue: Timeout in Integration Tests
|
||||
|
||||
**Problem:** Tests hang or timeout
|
||||
|
||||
**Solution:**
|
||||
- Check `mockWebServer.enqueue()` is called before request
|
||||
- Verify timeout configuration in RagClientService
|
||||
- Use shorter timeouts in tests
|
||||
|
||||
### Issue: Flaky Retry Tests
|
||||
|
||||
**Problem:** Retry tests sometimes fail
|
||||
|
||||
**Solution:**
|
||||
- Don't rely on timing-based assertions
|
||||
- Use deterministic mock responses
|
||||
- Verify request count instead of timing
|
||||
|
||||
