Macro db_test

macro_rules! db_test {
    ($backend:expr) => { ... };
    ($backend:expr, $config:expr) => { ... };
}

A more ergonomic macro for database operations that hides all the boxing complexity

This macro provides a clean syntax for database operations without requiring the user to manually use Box::new(), Box::pin(), or boxed_async!

Example:

use testkit_core::db_test;

#[tokio::test]
async fn test_database() {
    let backend = MockBackend::new();
     
    // Using the macro for a clean API
    let ctx = db_test!(backend)
        .setup_async(|conn| async {
            // Setup operations...
            Ok(())
        })
        .transaction(|conn| async {
            // Transaction operations...
            Ok(())
        })
        .run()
        .await
        .expect("Test failed");
}
