# End-to-End API Tests
|
|
|
|
These tests make real HTTP requests to the running Tatlock API server to verify the complete stack works correctly.
|
|
|
|
## Prerequisites
|
|
|
|
1. **Server must be running** on `http://localhost:8000`
|
|
2. **Ollama must be running** with `mistral-nemo:latest` model
|
|
3. **Redis must be running** (for benchmarking)
|
|
|
|
## Running the Tests
|
|
|
|
### Start the server first:
|
|
|
|
```bash
|
|
# Terminal 1: Start the server
|
|
uvicorn src.main:app --reload
|
|
```
|
|
|
|
### Run the E2E tests:
|
|
|
|
```bash
|
|
# Terminal 2: Run E2E tests
|
|
PYTHONPATH=/mnt/media/Projects/tatlock pytest tests/e2e/ -v
|
|
```
|
|
|
|
### Run specific test categories:
|
|
|
|
```bash
|
|
# Test chat completions only
|
|
pytest tests/e2e/test_api_endpoints.py::TestChatCompletionsE2E -v
|
|
|
|
# Test responses API only
|
|
pytest tests/e2e/test_api_endpoints.py::TestResponsesAPIE2E -v
|
|
|
|
# Test streaming only
|
|
pytest tests/e2e/test_api_endpoints.py::TestStreamingE2E -v
|
|
|
|
# Test Steward integration specifically
|
|
pytest tests/e2e/test_api_endpoints.py::TestStewardIntegration -v
|
|
```
|
|
|
|
## What These Tests Verify
|
|
|
|
### 1. Chat Completions Endpoint (`/v1/chat/completions`)
|
|
|
|
- ✅ Simple calculations trigger calculator tool
|
|
- ✅ Search queries trigger web search
|
|
- ✅ Multi-turn conversations maintain context
|
|
- ✅ Complex requests use multiple tools
|
|
- ✅ Simple greetings don't trigger unnecessary tools
|
|
- ✅ Date/time queries trigger datetime tools
|
|
|
|
### 2. Responses API Endpoint (`/v1/responses`)
|
|
|
|
- ✅ Reasoning output includes Steward's analysis
|
|
- ✅ Multi-turn conversations show in Steward reasoning
|
|
- ✅ Response structure follows OpenAI Responses format
|
|
|
|
### 3. Streaming
|
|
|
|
- ✅ Chat completions streaming works
|
|
- ✅ Steward reasoning appears in stream
|
|
- ✅ Proper SSE format with chunks
|
|
|
|
### 4. Error Handling
|
|
|
|
- ✅ Invalid model returns 404
|
|
- ✅ Missing required fields return 422
|
|
- ✅ Invalid parameters return 422
|
|
|
|
### 5. Steward Integration
|
|
|
|
- ✅ Steward recommends correct capabilities
|
|
- ✅ Steward detects conversation context
|
|
- ✅ Steward analysis appears in all responses
|
|
|
|
## Expected Behavior
|
|
|
|
When tests run, you should see in the server logs:
|
|
|
|
```
|
|
INFO creating_response_with_steward
|
|
INFO preprocessing_request
|
|
INFO operation_started operation=steward_analysis
|
|
INFO steward_analysis_complete recommended=[...] complexity=simple
|
|
INFO tatlock_run_with_scoped_tools
|
|
INFO tatlock_response_generated
|
|
INFO tool_tracking_finalized
|
|
```
|
|
|
|
## Test Scenarios
|
|
|
|
### Simple Calculation
|
|
```
|
|
User: "What is 144 divided by 12?"
|
|
Expected: Calculator tool used, answer is "12"
|
|
```
|
|
|
|
### Web Search
|
|
```
|
|
User: "What is the capital of France?"
|
|
Expected: Search may be used, answer mentions "Paris"
|
|
```
|
|
|
|
### Multi-Turn
|
|
```
|
|
User: "What is 15 times 4?"
|
|
Assistant: "60"
|
|
User: "Now add 20 to that result."
|
|
Expected: Context recognized, answer is "80"
|
|
```
|
|
|
|
### Combined Tools
|
|
```
|
|
User: "Calculate the square root of 256, then search for what number squared equals that result."
|
|
Expected: Both calculator and search recommended
|
|
```
|
|
|
|
### Date/Time
|
|
```
|
|
User: "What is today's date?"
|
|
Expected: Datetime tool used, current date returned
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
### Tests fail with connection error
|
|
|
|
Make sure the server is running:
|
|
```bash
|
|
uvicorn src.main:app --reload
|
|
```
|
|
|
|
### Tests timeout
|
|
|
|
- Check that Ollama is running and responsive
|
|
- Increase timeout in test file if needed (default: 60s)
|
|
|
|
### Tool usage not detected
|
|
|
|
- Check server logs to see if tools are actually being called
|
|
- Verify Steward preprocessing is happening (look for `steward_analysis` logs)
|
|
|
|
### Inconsistent results
|
|
|
|
- LLM responses can vary - tests check for key indicators rather than exact text
|
|
- If a test occasionally fails, it might be due to LLM variance
|
|
- Check the actual response content in the test output
|
|
|
|
## Coverage
|
|
|
|
These tests complement the unit and integration tests by:
|
|
|
|
1. **Testing the full HTTP stack** - Request parsing, routing, middleware
|
|
2. **Testing real LLM behavior** - Not mocked, actual Ollama responses
|
|
3. **Testing real tool execution** - Calculator, datetime, search actually run
|
|
4. **Testing Steward preprocessing** - Real analysis and tool scoping
|
|
5. **Testing error handling** - HTTP error codes and error responses
|
|
|
|
Together with unit/integration tests, this provides comprehensive coverage of the entire system.
