Testing Reference

nautilus_adapter_sdk.testing.compliance

Adapter compliance test suite for validating adapter implementations.

AdapterComplianceSuite

Compliance test harness for adapter implementations.

Parameterised via adapter_factory (a callable returning an Adapter instance) and source_config (the SourceConfig to connect with).

Usage::

suite = AdapterComplianceSuite(
    adapter_factory=lambda: MyAdapter(),
    source_config=SourceConfig(id="s1", type="mytype"),
)
await suite.test_connect_execute_close_lifecycle()
