|
|
|
|
### Uncovered Areas
|
|
1. **Background execution** (lines 248-350):
|
|
- Full strategy engine execution
|
|
- Performance metric calculation
|
|
- Progress broadcasting internals
|
|
|
|
2. **Model loading** (lines 104-210):
|
|
- Historical model version loading
|
|
- Time-based model selection
|
|
- Model cache integration
|
|
|
|
3. **Advanced features**:

|
|
|
|
## Test Execution
|
|
|
|
### Prerequisites
|
|
- PostgreSQL (for repository storage)
|
|
- Mock repositories (provided in `mock_repositories.rs`)
|
|
- Tokio async runtime
|
|
|
|
### Running Tests
|
|
```bash
|
|
# Run all service tests
|
|
cargo test -p backtesting_service --test service_tests
|
|
|
|
# Run specific test
|
|
cargo test -p backtesting_service test_start_backtest_success
|
|
|
|
# Run with output
|
|
cargo test -p backtesting_service --test service_tests -- --nocapture
|
|
```
|
|
|
|
### Test Features
|
|
- **Async execution**: All tests use `#[tokio::test]`
|
|
- **Isolation**: Each test creates fresh service instance
|
|
- **Concurrency**: Tests validate parallel backtest execution
|
|
- **Error handling**: All error paths explicitly tested
|
|
|
|
## Quality Standards Met
|
|
|
|
✅ **Mock gRPC requests/responses** - tonic::Request/Response used
|
|
✅ **Test all error paths** - 4/4 tonic::Status codes tested
|
|
✅ **Validate protobuf serialization** - Request/response conversion verified
|
|
✅ **Concurrent backtest isolation** - 2 concurrency tests
|
|
✅ **No workarounds** - Real mock implementations, no stubs
|
|
✅ **Edge cases** - Invalid inputs, resource limits, not found scenarios
|
|
