Cooperative async patterns using explicit state machines, completions, and re-entrancy safeguards for Turso's I/O model. \n \n Core types: IOResult<T> (returns Done or IO requiring re-call) and Completion for tracking individual operations \n CompletionGroup aggregates multiple completions into one, with nesting and cancellation support \n State machine pattern encodes progress in enum variants to safely handle re-entry across yield points \n Critical pitfall: mutating shared state before y

Modern patterns for testing async/await code with Swift Testing framework.

When working with Agentica's async REPL harness for testing.

Comprehensive guidance for implementing asynchronous Python applications using asyncio, concurrent programming patterns, and async/await for building high-performance, non-blocking systems.

Test @Scheduled and @Async methods directly without waiting for actual execution. \n \n Call async and scheduled methods directly in tests instead of relying on Spring's async executor or scheduling intervals \n Use CompletableFuture.get() with explicit timeouts to wait for async results, and Awaitility.await() for polling-based assertions on state changes \n Mock dependencies that async methods call, then verify interactions after completion using Mockito \n Test exception handling by catching

FastAPI async patterns for building high-performance, concurrent APIs with optimal resource usage. \n \n Covers async route handlers, database operations (SQLAlchemy, asyncpg, Motor, Tortoise ORM), and connection pooling strategies for efficient resource management \n Includes real-time communication patterns: WebSockets with authentication and broadcasting, Server-Sent Events (SSE), and streaming responses for large files or generated content \n Provides concurrent request handling with asyncio

Comprehensive guide to asyncio, concurrent patterns, and async/await for building high-performance, non-blocking Python applications. \n \n Covers core concepts (event loops, coroutines, tasks, futures) and 10+ fundamental and advanced patterns including concurrent execution, error handling, timeouts, context managers, and producer-consumer workflows \n Includes real-world examples for web scraping with aiohttp, async database operations, and WebSocket servers \n Provides performance best practi
