Api And Backend Testing

via “comprehensive backend test suite with docker environment”

Portable Python dataframe API across 20+ backends.

Unique: Implements a shared test suite (ibis/backends/tests/) that runs against all backends, with automatic skipping for unsupported features via decorators (e.g., @pytest.mark.notimplemented). This ensures consistent behavior across backends and makes it easy to add new backends by inheriting from base test classes. Docker Compose is used to manage database services, enabling reproducible testing across different environments.

vs others: More comprehensive than backend-specific tests (which only test one backend) and more maintainable than duplicating tests for each backend. Comparable to Polars' test infrastructure but with support for 20+ backends instead of just one.
