From fe233b2f8f62c74c802f7cf3663bfd6fabce03a7 Mon Sep 17 00:00:00 2001 From: Cameron Date: Wed, 4 Feb 2026 17:51:23 -0800 Subject: [PATCH] feat: add e2e tests with Letta Cloud (#149) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit E2E testing infrastructure that tests the full message flow against a real Letta Cloud agent. Changes: - Add MockChannelAdapter for simulating inbound/outbound messages - Add e2e/bot.e2e.test.ts with 4 e2e tests: - Simple message/response - /status command - /help command - Conversation context retention - Add 'mock' to ChannelId type - Update CI workflow with separate e2e job (uses secrets) - Add npm run test:e2e script E2E tests require: - LETTA_API_KEY (already in repo secrets) - LETTA_E2E_AGENT_ID (needs to be added) E2E tests are skipped locally without these env vars.
