/// ASYNC INSERT TEST SUITE - Comprehensive Testing for SqlSugar Async Operations
|

/// ═══════════════════════════════════════════════════════════════════════════════
|
||||
///
|
||||
/// PURPOSE:
|
||||
/// Tests all async insert methods in SqlSugar ORM with focus on:
|
||||
/// - Basic async insert operations (ExecuteCommandAsync, ExecuteReturnIdentityAsync, etc.)
|
||||
/// - Snowflake ID generation for distributed systems
|
||||
/// - CancellationToken support (CRITICAL - previously untested)
|
||||
/// - Error handling and edge cases
|
||||
///
|
||||
/// PRIORITY: 🔴 CRITICAL - 97% of async methods were previously untested
|
||||
///
|
||||
/// USAGE:
|
||||
/// // Run all tests
|
||||
/// NewUnitTest.AsyncInsert();
|
||||
///
|
||||
/// // Run individual test
|
||||
/// NewUnitTest.AsyncInsert_ExecuteCommandAsync();
|
||||
///
|
||||
/// TEST COVERAGE:
|
||||
/// ✅ ExecuteCommandAsync() - Basic async insert
|
||||
/// ✅ ExecuteReturnIdentityAsync() - Return identity value
|
||||
/// ✅ ExecuteReturnBigIdentityAsync() - BIGINT identity
|
||||
/// ✅ ExecuteReturnEntityAsync() - Return full entity with populated fields
|
||||
/// ✅ ExecuteReturnPkListAsync() - Bulk insert with PK list
|
||||
/// ✅ ExecuteReturnSnowflakeIdAsync() - Distributed ID generation
|
||||
/// ✅ ExecuteReturnSnowflakeIdListAsync() - Bulk Snowflake IDs
|
||||
/// ✅ CancellationToken support across all methods
|
||||
/// ✅ Transaction support
|
||||
/// ✅ Concurrent operations
|
||||
/// ✅ Error scenarios
|
||||
///
|
||||
/// DEPENDENCIES:
|
||||
/// - Order entity (with identity column)
|
||||
/// - OrderSnowflake entity (long PK without identity)
|

/// - OrderItem entity (for navigation property tests)
