 ## Running the tests
 
-1. Run the tests
+1. Run all tests (excluding those requiring real DBs, see item 3):
     ```bash
-    uv run pytest -v -s client/test_client_factory.py
+    uv run pytest
     ```
 
+    ```
+
+    **Useful Flags:**
+    - `-v` (verbose): Shows more detailed output, including each test name as it runs.
+    - `-s` (no capture): Allows stdout (print statements) to show in the console. Useful for debugging.
+
+    Example with flags:
+    ```bash
+    uv run pytest -v -s
+    ```
+
+    Note: Some tests require external databases (PostgreSQL, MySQL) and will be skipped if the corresponding environment variables (`POSTGRES_TEST_DSN`, `MYSQL_TEST_DSN`) are not set.
+
+2. Run specific tests:
+    ```bash
+    # Run a specific test file
+    uv run pytest tests/client/test_client_factory.py
+
+    # Run a specific test function
+    uv run pytest tests/client/test_client_factory.py::test_client_factory_connect_with_url
+
+    # Run tests in a specific folder
+    uv run pytest tests/client/
+    ```
+
+3. Run database integration tests (requires Docker):
+    ```bash
+    ./scripts/run_db_tests.sh
+    ```
+
+    This script will:
+    - Start PostgreSQL and MySQL containers using Docker Compose.
+    - Run the database integration tests.
+    - Stop the containers after tests finish.
+
+    You can also run tests for a specific database:
+    ```bash
+    ./scripts/run_db_tests.sh --postgres
+    # or
+    ./scripts/run_db_tests.sh --mysql
+    ```
+
+    To keep the databases running for debugging:
+    ```bash
+    ./scripts/run_db_tests.sh --debug
+    ```
+    (Follow the onscreen instructions to export DSNs and run pytest manually).
+
 In case of failures, you can clean up the cache:
 
 1. `uv clean`
