From 75b84fdc8dc8390f2dd0f97cf5ec95c708c0c993 Mon Sep 17 00:00:00 2001 From: Enmanuel Date: Thu, 9 Apr 2026 20:13:36 +0000 Subject: [PATCH] =?UTF-8?q?test:=20a=C3=B1adir=20tests=20para=20handleEven?= =?UTF-8?q?t,=20runLLM=20y=20tool-use=20loop?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Tests de command routing: builtin help/ping, comando desconocido, RegisterCommand, alias, ACL deniega comando. Tests de reglas + LLM: DM sin reglas cae a LLM, DM sin LLM ignora, regla matchea ejecuta accion, ActionKindReply estatico, ActionKindLLM invoca CompleteFunc, mencion sin reglas cae a LLM, mensaje sin match ni mencion se ignora, LLM action sin LLM configurado. Tests de tool-use loop: tool call ejecuta y retorna, tool call falla pasa error al LLM, max iterations se respeta, RBAC deniega tool call, error de LLM se propaga. Infraestructura: mockCompleteFunc con respuestas configurables, spyMatrixSender que graba mensajes, newTestAgent minimal.
