 # Snowpark connector testing
 
-Execution of automated tests for Snowpark connector requires real Snowflake instance access. Therefore tests located in this folder are **disabled** by default from pytest execution scope using [conftest.py](conftest.py).
+Execution of connection tests for Snowpark connector requires real Snowflake instance access.
 
-[Makefile](/Makefile) provides separate argument ``test-snowflake-only`` to run only tests related to Snowpark connector. To run tests one need to provide Snowflake connection parameters via environment variables:
-* SNOWSQL_ACCOUNT - Snowflake account name with region. Ex `ab12345.eu-central-2`
-* SNOWSQL_WAREHOUSE - Snowflake virtual warehouse to use
-* SNOWSQL_DATABASE - Database to use
-* SNOWSQL_SCHEMA - Schema to use when creating tables for tests
-* SNOWSQL_ROLE - Role to use for connection
-* SNOWSQL_USER - Username to use for connection
-* SNOWSQL_PWD - Plain password to use for connection
-
-All environment variables need to be provided for tests to run.
-
-Here is example shell command to run snowpark tests via make utility:
-```bash
-SNOWSQL_ACCOUNT='ab12345.eu-central-2' SNOWSQL_WAREHOUSE='DEV_WH' SNOWSQL_DATABASE='DEV_DB' SNOWSQL_ROLE='DEV_ROLE' SNOWSQL_USER='DEV_USER' SNOWSQL_SCHEMA='DATA' SNOWSQL_PWD='supersecret' make test-snowflake-only
-```
-
-Currently running tests supports only simple username & password authentication and not SSO/MFA.

-As of Mar-2023, the snowpark connector only works with Python 3.8.
+As of Oct-2024, the snowpark connector works with Python 3.9, 3.10 and 3.11. 3.12 is not supported yet.
 
 ## Snowflake permissions required
 Credentials provided via environment variables should have following permissions granted to run tests successfully:

-## Extending tests
-Contributors adding new tests should add `@pytest.mark.snowflake` decorator to each test. Exclusion of Snowpark-related pytests from overall execution scope in [conftest.py](conftest.py) works based on markers.
