What?
Add a testing example for
ToolLoopAgentto the Testing docs.Why?
The testing page covers
generateText,streamText,generateObject, andstreamObject, but has no example forToolLoopAgent. This was reported in #12616.How?
Added a section showing how to use
MockLanguageModelV3withmockValuesto simulate a multi-step tool loop:tool-call(weather tool)The example demonstrates the key pattern for testing agents: providing multiple mock responses via
mockValuesto simulate the tool loop.Fixes #12616
