+'''FAST Airbyte Standard Tests
+
+This module provides a set of base classes for declarative connector test suites.
+The goal of this module is to provide a robust and extensible framework for testing Airbyte
+connectors.
+
+Example usage:
+
+```python
+# `test_airbyte_standards.py`
+from airbyte_cdk.test import standard_tests
+
+pytest_plugins = [
+    "airbyte_cdk.test.standard_tests.pytest_hooks",
+]
+
+
+class TestSuiteSourcePokeAPI(standard_tests.DeclarativeSourceTestSuite):
+    """Test suite for the source."""
+```
+
+Available test suites base classes:
+- `DeclarativeSourceTestSuite`: A test suite for declarative sources.
+- `SourceTestSuiteBase`: A test suite for sources.
+- `DestinationTestSuiteBase`: A test suite for destinations.
