Summary

• Expand unit test coverage across AgentCube control plane, data plane, and tooling.
• Establish baseline coverage targets (>=70% for Go packages, smoke coverage for Python CLI/SDK) with CI reporting.

Motivation

• Protect the rapidly evolving proposal codebase from regressions as we bring components online.
• Build confidence for future contributors and reviewers by providing fast feedback loops.

Goals

• Capture current coverage numbers and document the biggest gaps.
• Add focused unit tests for critical behaviors across the components listed below.
• Wire coverage reporting into CI (Go and Python) so we can track improvements over time.

Workstreams

Go control plane & services

• pkg/agentd: cover runtime registration, lifecycle orchestration, and error paths.
• pkg/picod: exercise execution pipeline, auth helpers, and filesystem utilities.
• pkg/router: validate session manager, HTTP/WebSocket handlers, and config parsing.
• pkg/workloadmanager: focus on sandbox/code interpreter controllers, auth/JWT helpers, and workload builder.
• pkg/store: ensure interface contract tests plus Redis/Valkey adapters (consider fake clients or testcontainers).
• pkg/common/types & shared utilities: add serialization/validation tests where missing.

Binaries & entrypoints

• cmd/agentd, cmd/router, cmd/workload-manager, cmd/picod: ensure flag parsing and wiring logic have basic coverage (e.g., using in-memory config).

CLI & Python SDK

• cli/agentcube: add pytest coverage for command behaviors and error handling.
• sdk-python: cover agentcube clients/utilities with mocked HTTP interactions.

Tooling & CI

• Update Makefile/CI to run go test ./... -coverprofile and surface coverage summary.
• Add Python test job (pytest) with coverage report for CLI/SDK.
• Document how to run the test suites locally (README or docs/devguide) and set initial coverage targets.

Exit Criteria

• Checklist above is tackled via focused follow-up issues/PRs linked back here.
• Coverage targets and CI jobs are in place, with documentation updated accordingly.
