The test measured how long sendMessage() took to return (~100ms), but sendMessage() returns immediately - tools execute asynchronously during streaming. **Root cause:** - Test assumed sendMessage() duration = tool execution time - In reality: sendMessage() invokes IPC and returns, tools run later during streaming - Tools DO correctly wait for init (via wrapWithInitWait), but test couldn't detect it **Fix:** 1. **Test timing:** Measure from fork to init-end completion (must be >2.5s for 3s init hook) 2. **Verify blocking:** Presence of both tool-call-end and init-end events proves tools waited (if tools didn't wait, they'd fail accessing non-existent files during init) 3. **Prevent fork-during-init:** Added check in WORKSPACE_FORK handler to reject forks when source workspace is initializing **Test infrastructure improvements:** - Centralized DEFAULT_TEST_MODEL constant - Moved provider setup into sendMessage() helper (eliminates ~50 lines of duplication) - Added guidance to AGENTS.md about avoiding manual test setup boilerplate **Test results:** - ✅ All 18 fork tests pass (both local and SSH runtimes) - ✅ Init blocking works correctly (no bug in initStateManager) - ✅ Fork-during-init properly rejected with clear error message --- docs/AGENTS.md | 1 + src/services/ipcMain.ts | 9 ++ tests/ipcMain/forkWorkspace.test.ts | 155 ++++++++++++++++++++++- tests/ipcMain/helpers.ts | 17 ++- tests/ipcMain/initWorkspace.test.ts | 11 +- tests/ipcMain/runtimeExecuteBash.test.ts | 36 +----- tests/ipcMain/runtimeFileEditing.test.ts | 42 ++---- 7 files changed, 193 insertions(+), 78 deletions(-) diff --git a/docs/AGENTS.md b/docs/AGENTS.md index 25fa973a0..2782b879d 100644 --- a/docs/AGENTS.md +++ b/docs/AGENTS.md @@ -229,6 +229,7 @@ This project uses **Make** as the primary build orchestrator.
