Interface IExpressionStatement

Expression statement for executing utility operations without value capture.

IMPORTANT: For API operations, use IApiOperateStatement instead. This statement type is primarily for utility operations that don't require capturing return values, and where the operation's side effect or validation is more important than its return value.

Common E2E testing scenarios:

• Validation assertions using TestValidator predicates (when not using predicate expressions)
• Utility function calls (console.log, debugging functions)
• Non-API side-effect operations
• Cleanup operations that don't involve API calls

Note: For most validation cases, prefer using predicate expressions (IEqualPredicate, IConditionalPredicate, etc.) instead of expression statements with TestValidator calls.

AI function calling usage: Select when the business action's execution is the goal, not data capture, and when the operation is NOT an API call.
