From d792018c0945dd08d29f5d7a931826f9f2e78689 Mon Sep 17 00:00:00 2001 From: Hangfei Lin Date: Wed, 9 Jul 2025 19:40:56 -0700 Subject: [PATCH] test: Adds test for streaming + function calls This commit includes a number of new tests for live streaming with function calls. These tests cover various scenarios: - Single function calls - Multiple function calls - Parallel function calls - Function calls with errors - Synchronous function calls - Simple streaming tools - Video streaming tools - Stopping a streaming tool - Multiple streaming tools simultaneously The tests use mock models and custom runners to simulate the interaction between the agent, model, and tools. They verify that function calls are correctly generated, executed, and that the expected data is returned.
