refactor: streamline test suite - cut 33 files, enable parallel execution (11.9x speedup)

Browse Source 
Remove duplicate, low-value, and fragmented test files while preserving
all meaningful coverage. Enable parallel test execution and remove
the entire benchmark infrastructure.

Key changes:
- Consolidate workflow-validator tests (13 files -> 3)
- Consolidate config-validator tests (9 files -> 3)
- Consolidate telemetry tests (11 files -> 6)
- Merge AI validator tests (2 files -> 1)
- Remove example/demo test files, mock-testing files, and already-skipped tests
- Remove benchmark infrastructure (10 files, CI workflow, 4 npm scripts)
- Enable parallel test execution (remove singleThread: true)
- Remove retry:2 that was masking flaky tests
- Slim CI publish-results job

Results: 224 -> 191 test files, 4690 -> 4303 tests, 121K -> 106K lines
Local runtime: 319s -> 27s (11.9x speedup)

# Performance Benchmarks
This directory contains performance benchmarks for critical operations in the n8n-mcp project.
## Running Benchmarks
### Local Development
```bash
# Run all benchmarks
npm run benchmark
# Watch mode for development
npm run benchmark:watch
# Interactive UI
npm run benchmark:ui
# Run specific benchmark file
npx vitest bench tests/benchmarks/node-loading.bench.ts
```
### CI/CD
Benchmarks run automatically on:
- Every push to `main` branch
- Every pull request
- Manual workflow dispatch
## Benchmark Suites
### 1. Node Loading Performance (`node-loading.bench.ts`)
- Package loading (n8n-nodes-base, @n8n/n8n-nodes-langchain)
- Individual node file loading
- Package.json parsing
### 2. Database Query Performance (`database-queries.bench.ts`)
- Node retrieval by type
- Category filtering
- Search operations (OR, AND, FUZZY modes)
- Node counting and statistics
- Insert/update operations
### 3. Search Operations (`search-operations.bench.ts`)
- Single and multi-word searches
- Exact phrase matching
- Fuzzy search performance
- Property search within nodes
- Complex filtering operations
### 4. Validation Performance (`validation-performance.bench.ts`)
- Node configuration validation (minimal, strict, ai-friendly)
- Expression validation
- Workflow validation
- Property dependency resolution
### 5. MCP Tool Execution (`mcp-tools.bench.ts`)
- Tool execution overhead
- Response formatting
- Complex query handling
## Performance Targets
| Operation | Target | Alert Threshold |
|-----------|--------|-----------------|
| Node loading | <100ms per package | >150ms |
| Database query | <5ms per query | >10ms |
| Search (simple) | <10ms | >20ms |
| Search (complex) | <50ms | >100ms |
| Validation (simple) | <1ms | >2ms |
| Validation (complex) | <10ms | >20ms |
| MCP tool execution | <50ms | >100ms |
## Benchmark Results
- Results are tracked over time using GitHub Actions
- Historical data available at: https://czlonkowski.github.io/n8n-mcp/benchmarks/
- Performance regressions >10% trigger automatic alerts
- PR comments show benchmark comparisons
## Writing New Benchmarks
```typescript
import { bench, describe } from 'vitest';
describe('My Performance Suite', () => {
bench('operation name', async () => {
// Code to benchmark
}, {
iterations: 100, // Number of times to run
warmupIterations: 10, // Warmup runs (not measured)
warmupTime: 500, // Warmup duration in ms
time: 3000 // Total benchmark duration in ms
});
});
```
## Best Practices
1. **Isolate Operations**: Benchmark specific operations, not entire workflows
2. **Use Realistic Data**: Load actual n8n nodes for realistic measurements
3. **Warmup**: Always include warmup iterations to avoid JIT compilation effects
4. **Memory**: Use in-memory databases for consistent results
5. **Iterations**: Balance between accuracy and execution time
## Troubleshooting
### Inconsistent Results
- Increase `warmupIterations` and `warmupTime`
- Run benchmarks in isolation
- Check for background processes
### Memory Issues
- Reduce `iterations` for memory-intensive operations
- Add cleanup in `afterEach` hooks
- Monitor memory usage during benchmarks
### CI Failures
- Check benchmark timeout settings
- Verify GitHub Actions runner resources
- Review alert thresholds for false positives

/**
* Tests for WorkflowValidator - Tool Variant Validation
*
* Tests the validateAIToolSource() method which ensures that base nodes
* with ai_tool connections use the correct Tool variant node type.
*
* Coverage:
* - Langchain tool nodes pass validation
* - Tool variant nodes pass validation
* - Base nodes with Tool variants fail with WRONG_NODE_TYPE_FOR_AI_TOOL
* - Error includes fix suggestion with tool-variant-correction type
* - Unknown nodes don't cause errors
