From f3a185cc4a0c88a5ceffbe73778b614c7f803a04 Mon Sep 17 00:00:00 2001 From: "ilblackdragon@gmail.com" Date: Sun, 22 Mar 2026 13:03:18 -0700 Subject: [PATCH] test(engine): add 8 CodeAct/RLM E2E tests with mock LLM MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Comprehensive test coverage for the Monty Python execution path: - codeact_simple_final: Python code calls FINAL('answer') → thread completes - codeact_tool_call_then_final: code calls test_tool() → FunctionCall suspends VM → MockEffects returns result → code resumes → FINAL() - codeact_pure_python_computation: sum([1,2,3,4,5]) → FINAL('Sum is 15') with no tool calls — pure Python in Monty - codeact_multi_step: first step prints output (no FINAL), second step sees output metadata and calls FINAL — tests iterative REPL flow - codeact_error_recovery: first step has NameError → error flows to LLM as stdout → second step recovers with FINAL — tests error transparency - codeact_context_variables_available: code accesses `goal` and `context` variables injected by the RLM context builder - codeact_multiple_tool_calls_in_loop: for loop calls test_tool() 3 times → 3 FunctionCall suspensions → all results collected → FINAL - codeact_llm_query_recursive: code calls llm_query('prompt') → VM suspends → MockLlm provides sub-agent response → result returned as Python string variable 93 tests passing (85 prior + 8 new), zero clippy warnings.
