test(31-03): 集成测试套件骨架 + docker compose fixture 脚本

ZaneL1u · ZaneL1u · commit a202563aa7f6 · 2026-04-19T17:51:00.000+08:00
- internal/cloudclaude/integration_test.go：6 个 TestIntegration_*
  覆盖 RESEARCH §6.2 全部场景（C4 / C5 / REQ-F2-B / REQ-F1-D /
  REQ-F7-C / C3）。build tag //go:build integration 隔离，默认
  go test ./... 不触发；CI 在 docker 可用时跑
  go test -tags=integration -count=1 -v ./internal/cloudclaude/。
  TestMain 在 fixture-up.sh 失败时 os.Exit(0) 优雅跳过，避免本地
  开发者无 docker 也阻塞 unit test。

- scripts/test-fixture-up.sh：起 Phase 29 镜像 local/managed-user:v3.0.0
  容器（cap_add SYS_ADMIN + /dev/fuse + apparmor=unconfined +
  CLOUD_CLAUDE_TEST_FIXTURE=1），轮询 30s 等待 sshd 就绪。

- scripts/test-fixture-down.sh：docker compose down -v 销毁容器
  并清理 /tmp/cloud-claude-fixture/。

未引入 testcontainers-go（避免 50+ indirect deps），全部用脚本化
docker compose fixture。C3 netem 场景占位 t.Skip，由 Phase 35
真机验收完整覆盖。

go test -tags=integration -count=1 -run x_no_run_x ./internal/cloudclaude/
静态编译通过。

+// 默认 `go test ./...` 不触发本文件（受 build tag `integration` 隔离）；
+// 完整执行需：
+//
+//	bash scripts/test-fixture-up.sh   # 起 Phase 29 镜像
+//	go test -tags=integration -count=1 -v ./internal/cloudclaude/
+//	bash scripts/test-fixture-down.sh
+//
+// CI 在 docker 可用环境下走上述命令；本地开发者可不安装 docker，
+// TestMain 会在 fixture-up.sh 失败时 os.Exit(0) 优雅跳过。
+//
+// 6 个 TestIntegration_* 用例覆盖 RESEARCH §6.2：
+//   - C4：Mutagen 版本不一致 → 降级 sshfs-only + MOUNT_MUTAGEN_VERSION_SKEW
+//   - C5：alpha 空 + beta 非空安全门 → MOUNT_MUTAGEN_SAFETY_GUARD + sync 未创建
+//   - REQ-F2-B：pkill -9 mutagen-agent ≤2s 降级
+//   - REQ-F1-D：dd 200MB 拒绝热同步 → MOUNT_MUTAGEN_WHITELIST_REJECT
+//   - REQ-F7-C：OAuth expiresAt:0 → 退出非 0、不进 claude
+//   - C3：netem drop 30s → 摘除 cold branch（依赖 tc，CI 兜底，本测试占位）
+//
+// 凭证注入策略：
+//
+//	推荐路径 (b)：测试代码直接 import internal/cloudclaude 包，
+//	构造 SSHConfig + AuthResponse 调 ConnectAndRunClaudeV3，
+//	绕过 main.go 的 LoadConfig + EntryClient 网关路径，无需 mock gateway。
