There was a problem hiding this comment.
Would it come under just testing infra change? Should it be moved to another PR?

Description
This PR upgrades the integration test harnesses across the SDK (
core,adk,langchain, andllamaindex) to support running integration tests against multiple Toolbox server configurations simultaneously.By parameterizing the
toolbox_server_urlfixture and updating the Cloud Build configurations, the CI will now spin up and test against two server instances:Motivation
This is a pure testing infrastructure change. It lays the groundwork for the upcoming
DRAFT-2026-v1protocol support, ensuring we can test backward compatibility (graceful protocol downgrading) against older servers without breaking any existing test cases.Note
The presubmits fail because in this PR, we configured the test suite to run against both stable (
5000) and draft (5001). It fails because it successfully negotiated the draft spec. This is fixed in the #703 branch (which is stacked on top of this PR).Note
This PR focusses only on parameterizing the tests. The fallback logic is broken at this stage which caused crashes against the stable server, so we added the
if "DRAFT" not in vfilter there temporarily. However, in the upcoming PR #703 that workaround is removed.
