## Phase 5A: Container Integration Tests (systemd-nspawn)

### Test 5A-1: Non-boot container execution — ✅ PASS
```
systemd-nspawn -D /var/lib/volt/containers/test-container --machine=volt-test-2 \
  /bin/sh -c "echo Hello; hostname; id; cat /etc/os-release"
```
**Result:** Container launched, executed commands, showed hostname `volt-test-2`, ran as `uid=0(root)`. Rootfs identified as **Debian 12 (bookworm)**. Exited cleanly.

### Test 5A-1b: Boot mode container — ❌ FAIL
```
systemd-nspawn -D /var/lib/volt/containers/test-container --machine=volt-test-1 -b --network-bridge=volt0
```
**Result:** `execv(/usr/lib/systemd/systemd, /lib/systemd/systemd, /sbin/init) failed: No such file or directory`
**Root cause:** The bootstrapped rootfs is a minimal Debian install without systemd/init inside. This is an **infrastructure issue** — the rootfs needs `systemd` installed to support boot mode.
**Fix:** `debootstrap --include=systemd,dbus` or `chroot /var/lib/volt/containers/test-container apt install systemd`

### Test 5A-2: volt ps shows containers — ⚠️ PARTIAL
```
volt ps containers → "No container workloads found."
```
**Result:** `volt ps` correctly shows services, but the container started via `systemd-nspawn` directly was not tracked by volt. This is expected — volt needs its own container orchestration layer (via `volt container create`) to track containers. Currently, `volt container list` returns "No containers running" even with a running nspawn. The `volt container create` → `volt container start` → `volt ps containers` pipeline is what needs to be implemented.

### Test 5A-3: Execute in container — ❌ FAIL (dependent on 5A-1b)
**Result:** Failed because boot container never started. The `machinectl shell` command requires a booted machine. Non-boot containers exit immediately after the command.

### Test 5A-4: Container networking — ✅ PASS
```
systemd-nspawn ... --network-bridge=volt0
```
**Result:** Network bridge attachment succeeded. `vb-volt-netDLIN` veth pair was created. The rootfs lacks `ip`/`iproute2` so we couldn't verify IP assignment inside, but the host-side plumbing worked. Bridge linkage with volt0 confirmed.

---

## Phase 5B: Service Management Tests

### Test 5B-1: volt service create — ✅ PASS
```
volt service create --name volt-test-svc --exec "/bin/sh -c 'while true; do echo heartbeat; sleep 5; done'"
→ "Service unit written to /etc/systemd/system/volt-test-svc.service"
```
**Result:** Unit file created correctly with proper `[Unit]`, `[Service]`, and `[Install]` sections. Added `Description=Volt managed service: volt-test-svc`, `After=network.target`, `Restart=on-failure`, `RestartSec=5`.

### Test 5B-2: volt service start — ✅ PASS
```
volt service start volt-test-svc → "Service volt-test-svc.service started."
volt service status volt-test-svc → Active: active (running)
```
**Result:** Service started, PID assigned (25669), cgroup created, heartbeat messages in journal.

### Test 5B-3: volt ps shows service — ✅ PASS
```
volt ps | grep volt-test → volt-test-svc  service  running  -  388.0 KB  25669  3s
```
**Result:** Service correctly appears in `volt ps` with type, status, memory, PID, and uptime.

### Test 5B-4: volt logs — ✅ PASS
```
volt logs volt-test-svc --tail 5
```
**Result:** Shows journal entries including systemd start message and heartbeat output. Correctly wraps `journalctl`.

### Test 5B-5: volt service stop — ✅ PASS
```
volt service stop volt-test-svc → "Service volt-test-svc.service stopped."
volt service status → Active: inactive (dead)
```
**Result:** Service stopped cleanly. Note: `volt service status` exits with code 3 for stopped services (mirrors systemctl behavior). The exit code triggers usage output — minor UX issue.

### Test 5B-6: volt service disable — ✅ PASS
```
volt service disable volt-test-svc → "Service volt-test-svc.service disabled."
```
**Result:** Service disabled correctly.

---

## Phase 5C: Network Tests

### Test 5C-1: volt net status — ✅ PASS
**Result:** Comprehensive output showing:
- Bridges: `virbr0` (DOWN), `volt0` (DOWN/no-carrier — expected, no containers attached)
- IP addresses: `eth0` 172.234.213.10/24, `volt0` 10.0.0.1/24, `virbr0` 192.168.122.1/24
- Routes: default via 172.234.213.1
- Listening ports: SSH (22), DNS (53 systemd-resolved + dnsmasq)

### Test 5C-2: volt net bridge list — ✅ PASS
**Result:** Shows detailed bridge info for `virbr0` and `volt0` via `ip -d link show type bridge`. Includes STP state, VLAN filtering, multicast settings. Production-quality output.

### Test 5C-3: volt0 bridge details — ✅ PASS
**Result:** `volt0` bridge confirmed: `10.0.0.1/24`, `fe80::d04d:94ff:fe6c:5414/64`. State DOWN (expected — no containers attached yet).

### Test 5C-4: volt net firewall list — ✅ PASS
**Result:** Full nftables ruleset displayed including:
- `ip filter` table with libvirt chains (LIBVIRT_INP, LIBVIRT_OUT, LIBVIRT_FWO, LIBVIRT_FWI, LIBVIRT_FWX)
- `ip nat` table with masquerade for virbr0 subnet + eth0
- `ip6 filter` and `ip6 nat` tables
- All tables show proper chain hooks and policies

### Test 5C-5: Dynamic bridge creation visible — ✅ PASS
**Result:** After creating `volt-test` bridge via `ip link add`, `volt net bridge list` immediately showed all 3 bridges (virbr0, volt0, volt-test). Cleanup via `ip link del` worked.

---

## Phase 5D: Performance Tuning Tests

### Test 5D-1: Sysctl get — ✅ PASS
```
volt tune sysctl get net.core.somaxconn → 4096
volt tune sysctl get vm.swappiness → 60
```

### Test 5D-2: Sysctl set — ✅ PASS
```
volt tune sysctl set vm.swappiness 10 → vm.swappiness = 10
sysctl vm.swappiness → vm.swappiness = 10  (confirmed)
volt tune sysctl set vm.swappiness 60 → restored
```
**Result:** Reads and writes sysctl values correctly. Changes verified with system `sysctl` command.

### Test 5D-3: Profile list — ✅ PASS
**Result:** Shows 8 tuning profiles: `server`, `desktop`, `latency`, `throughput`, `balanced`, `powersave`, `vm-host`, `container-host`. Good naming and descriptions.

### Test 5D-4: volt tune show — ✅ PASS
**Result:** Shows overview: CPU Governor (unavailable — no cpufreq on VM), Swappiness (60), IP Forwarding (1), Overcommit (0), Max Open Files, Somaxconn (4096).

### Test 5D-5: volt tune profile apply — ⚠️ STUB
```
volt tune profile apply server → "not yet implemented"
```
**Note:** No `--dry-run` flag either. Profile apply is planned but not yet implemented.

---

## Phase 5E: Task/Timer Tests

### Test 5E-1: volt task list — ✅ PASS
**Result:** Lists all 13 system timers with NEXT, LEFT, LAST, PASSED, UNIT, and ACTIVATES columns. Wraps `systemctl list-timers` cleanly.

### Test 5E-2: Custom timer visible — ✅ PASS
**Result:** After creating `volt-test-task.timer` and starting it, `volt task list` showed 14 timers with the new one at the top (next fire in ~19s).

### Test 5E-3: volt task run — ❌ FAIL
```
volt task run volt-test-task
→ "Failed to start volt-task-volt-test-task.service: Unit volt-task-volt-test-task.service not found."
```
**Root cause:** `volt task run` prepends `volt-task-` to the name, looking for `volt-task-volt-test-task.service` instead of `volt-test-task.service`. This is a **naming convention issue** — volt expects tasks it created (with `volt-task-` prefix) rather than arbitrary systemd timers.
**Fix:** Either document the naming convention or allow `volt task run` to try both `volt-task-<name>` and `<name>` directly.

### Test 5E-4: Manual task execution — ✅ PASS
```
systemctl start volt-test-task.service → success
journalctl shows: "Volt task executed"
```
**Result:** The underlying systemd timer/service mechanism works correctly.

---

## Phase 5F: Output Format Validation

### Test 5F-1: JSON output — ✅ PASS
```
volt ps -o json | python3 -m json.tool → valid JSON
```
**Result:** Outputs valid JSON array of objects with fields: `name`, `type`, `status`, `cpu`, `mem`, `pid`, `uptime`.

### Test 5F-2: YAML output — ✅ PASS
```
volt ps -o yaml → valid YAML
```
**Result:** Proper YAML list with `-` delimiters and key-value pairs.

### Test 5F-3: volt system info — ✅ PASS
**Result:** Beautiful formatted output with:
- Version/build info
- Hostname, OS, kernel, arch
- CPU model and core count
- Memory total/available
- Disk usage
- System uptime

### Test 5F-4: volt ps --all — ✅ PASS
**Result:** Shows 60 services including exited oneshots. Table formatting is clean with proper column alignment. ANSI color codes used for status (green=running, yellow=exited).

---

## Phase 5G: Compose File Validation

### Test 5G-1: volt compose config — ✅ PASS
```
volt compose config → "✓ Compose file is valid"
```
**Result:** Parses and validates the compose YAML correctly. Re-outputs the normalized config showing services and networks.

### Test 5G-2: volt compose up — ⚠️ STUB
```
volt compose up → "Stack creation not yet fully implemented."
```
**Result:** Parses the file, shows what it would create (2 services, 1 network with types), but doesn't actually create anything. Good progress indication.

### Test 5G-3: volt compose down — ⚠️ STUB
```
volt compose down → "not yet implemented"
```

---

## Additional Tests

### volt help — ✅ PASS
Comprehensive help with 6 categories: Workload, Infrastructure, Observability, Composition, System, Shortcuts. 30+ commands listed.

### volt version — ✅ PASS
Shows version, build date, git commit.

### Error handling — ✅ PASS
- Unknown command: clear error message + help suggestion
- Nonexistent service status: proper error with exit code 4
- Nonexistent service logs: "No entries" (graceful, no crash)

### volt status — ✅ PASS
Same as `volt system info`. Clean system overview.

### volt cluster status — ✅ PASS
Shows cluster overview with density comparison (32x over traditional VMs). Currently 0 nodes.

### volt container list — ✅ PASS
Returns "No containers running" (correct — no containers managed by volt).

### volt volume list — ⚠️ STUB
"Not yet implemented"

### volt top — ⚠️ STUB
"Not yet implemented" with helpful alternatives (volt ps, htop, systemd-cgtop).

### volt events — ⚠️ STUB
"Not yet implemented"

## What Works Fully (Production-Ready)

1. **Service lifecycle** — create, start, stop, disable, status, logs — complete pipeline
2. **Process listing** — `volt ps` with JSON/YAML/table/wide output, `--all` flag
3. **Network status** — bridges, firewall, interfaces, routes, ports
4. **Sysctl tuning** — read and write kernel parameters
5. **Task listing** — system timer enumeration
6. **System info** — comprehensive platform information
7. **Config validation** — compose file parsing and validation
8. **Error handling** — proper exit codes, clear error messages
9. **Help system** — well-organized command hierarchy with examples

## What's Skeleton/Stub (Needs Implementation)

1. **`volt compose up/down`** — Parses config but doesn't create services
2. **`volt tune profile apply`** — Profiles listed but can't be applied
3. **`volt volume list`** — Not implemented
4. **`volt top`** — Not implemented (real-time monitoring)
5. **`volt events`** — Not implemented
6. **`volt container create/start`** — The container management pipeline needs the daemon to track nspawn instances

## Bugs/Issues Found

1. **`volt task run` naming** — Prepends `volt-task-` prefix, won't run tasks not created by volt. Should either fall back to direct name or document the convention clearly.
2. **`volt service status` exit code** — Returns exit 3 for stopped services (mirrors systemctl) but then prints full usage/help text, which is confusing. Should suppress usage output when the command syntax is correct.
3. **Container rootfs** — Bootstrapped rootfs at `/var/lib/volt/containers/test-container` lacks systemd (can't boot) and iproute2 (can't verify networking). Needs enrichment for full testing.

## Infrastructure Limitations

- **No KVM/nested virt** — Shared Linode doesn't support KVM. Cannot test `volt vm` commands. Need bare-metal or KVM-enabled VPS for VM testing.
- **No cpufreq** — CPU governor unavailable in VM, so `volt tune show` reports "unavailable".
- **Container rootfs minimal** — Debian 12 debootstrap without systemd or networking tools.

## Recommendations for Next Steps

1. **Priority: Implement `volt container create/start/stop`** — This is the core Voltainer pipeline. Wire it to `systemd-nspawn` with `machinectl` registration so `volt ps containers` tracks them.
2. **Priority: Implement `volt compose up`** — Convert validated compose config into actual `volt service create` calls + bridge creation.
3. **Fix `volt task run`** — Allow running arbitrary timers, not just volt-prefixed ones.
4. **Fix `volt service status`** — Don't print usage text when exit code comes from systemctl.
5. **Enrich test rootfs** — Add `systemd`, `iproute2`, `curl` to container rootfs for boot mode and network testing.
6. **Add `--dry-run`** — To `volt tune profile apply`, `volt compose up`, etc.
7. **Get bare-metal Linode** — For KVM/Voltvisor testing (dedicated instance required).
8. **Implement `volt top`** — Use cgroup stats + polling for real-time monitoring.
9. **Container image management** — `volt image pull/list` to download and manage rootfs images.
10. **Daemon mode** — `volt daemon` for long-running container orchestration with health checks.
