Contract-first testing enforces strict schema validation and deterministic fixtures across multi-agent boundaries. This standard ensures interfaces fail safely using valid and invalid inputs before real execution, blocking unsafe merges across cross-process services like Gateway and Orchestrator.

Testing SSE streaming events requires replayable streaming tests within your CI pipeline. This approach validates streaming behaviors deterministically, ensuring that cross-protocol changes and artifact-to-runtime capabilities are verified before integration.

CI quality gates block unsafe merges by making PR reviews contingent on passing defined test matrices. You set up gates covering unit, component, and cross-process integration tests, ensuring contracts, fixtures, and process separation remain intact.

Contract-first schema validation applies to Docker demo paths and persistence layers. It requires deterministic fake inputs and strict fixture rules to validate cross-boundary interfaces, ensuring changes across these runtime behaviors fail safely.

Security regression checks are needed to prevent unsafe changes by validating redaction, iframe sandboxing, and confirm_action for high-risk tools. These controls ensure security guardrails remain intact during cross-service and cross-protocol modifications.

Unit tests alone cannot verify cross-process integration or streaming behaviors. Limitations include missing failure-path coverage, fallback correctness, and security regression controls, requiring a comprehensive test matrix to prevent fragile multi-agent changes.
