The session ID is used for resource subscriptions and unsubscriptions instead of a hardcoded default. + +### ✅ Extensionless File Handling +**File:** `src/tools/workspace.rs` + +Extensionless files like Makefile, Dockerfile, Jenkinsfile, and common dotfiles are now properly categorized using the new `filename_to_language()` function. + +### ✅ Language Category Naming +**File:** `src/tools/workspace.rs` + +The `extension_to_language()` function now returns `"other"` for unknown extensions instead of the misleading `"binary"`. + +--- + +## Future Enhancements (from Code Review) + +The following enhancements are documented for future implementation: + +### Medium Priority + +#### 1. Progress Reporting Improvements +**File:** `src/mcp/progress.rs` + +- Add warning log when `complete()` is called without a total being set +- Add debug logging when notification receiver is dropped + +```rust +// In complete() method +if self.total.is_none() { + tracing::warn!("complete() called without total set"); +} + +// In send methods +if self.sender.send(notification).is_err() { + tracing::debug!("Progress notification receiver dropped"); +} +``` + +#### 2. TypeScript Function Detection Accuracy +**File:** `src/tools/workspace.rs` + +The current detection using `line.contains("function ")` can produce false positives on comments like `// This function does...`. A more precise approach: + +```rust +// Check if "function " appears at start or after export/async keywords +let trimmed = line.trim(); +if trimmed.starts_with("function ") + || trimmed.starts_with("export function ") + || trimmed.starts_with("async function ") + || trimmed.starts_with("export async function ") { + // Process as function declaration +} +``` + +### Low Priority + +#### 3. Async I/O in Resource Discovery +**File:** `src/mcp/resources.rs` + +Some operations use blocking I/O patterns in async context. Consider using `tokio::task::spawn_blocking` for CPU-intensive operations or ensuring all file I/O uses async variants consistently. + +#### 4. Silent Fallback on Malformed Params +**File:** `src/mcp/server.rs` + +Some handlers silently use defaults when params are malformed. Consider adding debug logging for better troubleshooting: + +```rust +let list_params: ListParams = params + .map(|v| { + serde_json::from_value(v.clone()).unwrap_or_else(|e| { + tracing::debug!("Failed to parse params, using defaults: {}", e); + ListParams::default() + }) + }) + .unwrap_or_default(); +``` + +--- + +## Known Limitations + +The following are documented limitations of the current implementation: + +| Limitation | Workaround | Future Fix | +|------------|------------|------------| +| TypeScript function false positives | Use `extract_symbols` for accurate results | Improve line-start detection | + +--- + +## References + +- [MCP Specification](https://modelcontextprotocol.io/specification) +- [MCP TypeScript SDK](https://github.com/modelcontextprotocol/typescript-sdk) +- [MCP Python SDK](https://github.com/modelcontextprotocol/python-sdk) + diff --git a/docs/TESTING.md b/docs/TESTING.md new file mode 100644 index 0000000..6ca2c6a --- /dev/null +++ b/docs/TESTING.md @@ -0,0 +1,213 @@ +# Testing Guide + +This document describes the testing strategy and how to run tests for Context Engine. + +## Test Overview + +| Category | Count | Location | Description | +|----------|-------|----------|-------------| +| Unit Tests | 170 | `src/**/*.rs` | Core functionality tests | +| Integration Tests | 11 | `tests/` | MCP protocol and CLI tests | + +## Running Tests + +### Quick Start + +```bash +# Run all unit tests +cargo test --lib + +# Run integration tests (basic CLI tests only) +cargo test --test mcp_integration_test + +# Run all tests including ignored integration tests +cargo test --test mcp_integration_test -- --ignored + +# Run everything +cargo test --all-targets +``` + +### Unit Tests + +Unit tests are embedded within source files using `#[cfg(test)]` modules. + +```bash +# Run all unit tests +cargo test --lib + +# Run tests for a specific module +cargo test --lib tools::language + +# Run a specific test +cargo test --lib test_detect_rust_symbol + +# Run with output +cargo test --lib -- --nocapture +``` + +### Integration Tests + +Integration tests are in the `tests/` directory and test the MCP server as a whole. + +```bash +# Run basic integration tests (CLI help/version) +cargo test --test mcp_integration_test + +# Run full MCP protocol tests (spawns server, sends JSON-RPC) +cargo test --test mcp_integration_test -- --ignored + +# Run a specific integration test +cargo test --test mcp_integration_test test_mcp_initialize -- --ignored +``` + +## Test Categories + +### 1.
