A System Under Test (SUT) defines the interface to a component or service you want to evaluate.

It specifies three contracts through schemas:

  • inputSchema: The structure of data the system accepts.
  • outputSchema: The structure of data the system produces.
  • configSchema: The parameters that modify system behavior.

This abstraction lets you evaluate any system as a black box, focusing on its interface rather than implementation details. It's particularly useful for systems with variable outputs or complex internal state.

Systems are templates - to run evaluations, pair them with a SystemConfig that provides specific parameter values.
