Performance Tuning
Optimize AIToTest for maximum speed and efficiency
Test Execution Optimization
Parallel Execution
// aitotest.config.js
module.exports = {
runner: {
parallel: true,
workers: 4,
maxConcurrency: 2,
grouping: {
strategy: 'file-size',
maxSize: '10MB'
}
}
}Test Sharding
// CI configuration
{
"sharding": {
"enabled": true,
"shards": 4,
"distribution": "even",
"timeout": 300
}
}Resource Management
Memory Usage
- Garbage collection
- Memory limits
- Resource cleanup
- Memory profiling
CPU Utilization
- Process allocation
- Thread pooling
- Load balancing
- CPU profiling
I/O Operations
- File caching
- Network pooling
- Batch operations
- I/O scheduling
Caching Strategies
Cache Configuration
module.exports = {
cache: {
enabled: true,
strategy: 'memory', // or 'redis', 'filesystem'
ttl: 3600,
maxSize: '1GB',
compression: true,
invalidation: {
patterns: ['**/*.test.js'],
triggers: ['git-commit', 'file-change']
}
}
}Test Suite Organization
Test Grouping
describe('User API', () => {
// Fast tests
describe('Validation', () => {
// Synchronous tests
});
// Slow tests
describe('Database', () => {
// Async operations
});
});Test Ordering
{
"testSequence": {
"order": [
"setup/**/*.test.js",
"unit/**/*.test.js",
"integration/**/*.test.js"
],
"priority": {
"high": ["auth/*.test.js"],
"low": ["legacy/*.test.js"]
}
}
}Performance Monitoring
Metrics Collection
{
"metrics": {
"collect": [
"execution-time",
"memory-usage",
"cpu-usage",
"io-operations"
],
"interval": 1000,
"exporters": [
"prometheus",
"grafana"
]
}
}Performance Alerts
{
"alerts": {
"execution-time": {
"threshold": "5m",
"action": "notify"
},
"memory-usage": {
"threshold": "2GB",
"action": "restart"
}
}
}Best Practices

- Shared fixtures
- Minimal setup
- Clean teardown
Resource Usage
- Connection pooling
- Memory management
- Async operations
- Proper cleanup
Test Design
