apalis-libsql 0.1.0

//! Turso Cloud integration test
//!
//! This test verifies that apalis-libsql works with Turso Cloud embedded replicas.
//!
//! IMPORTANT: These tests use Box::leak to create 'static references for LibsqlStorage.
//! This is acceptable for test code but should not be used in production.
//!
//! FIXED ISSUES:
//! 1. ExecuteReturnedRows error: Changed execute() to query() for SELECT statements
//! 2. SIGSEGV during cleanup: Use separate temporary files for each test to avoid SQLite WAL conflicts
//!
//! USAGE:
//! # Run all tests (may show SIGSEGV during final cleanup, but all tests pass):
//! cargo test --test turso_cloud -- --test-threads=1 --nocapture
//!
//! # Run individual tests (recommended, no SIGSEGV):
//! cargo test --test turso_cloud test_turso_cloud_connection -- --nocapture
//! cargo test --test turso_cloud test_turso_cloud_task_lifecycle -- --nocapture
//! cargo test --test turso_cloud test_turso_sync_roundtrip -- --nocapture
//!
//! Required environment variables:
//! - TURSO_DATABASE_URL: The Turso database URL (e.g., libsql://your-db.turso.io)
//! - TURSO_AUTH_TOKEN: The JWT authentication token
