Running `nix flake check` does NOT +execute VM tests. VM tests are expensive (QEMU boot per host) and would slow down local +development. They execute only in CI via a separate Woodpecker workflow +(`.woodpecker/test-vm.yaml`) on pull request events. + +## Testing Philosophy + +Scenario tests exist to validate **custom modules and logic from this repository** — +not upstream nixpkgs module behavior. nixpkgs modules (postgresql, openssh, +prometheus, pgvector, etc.) are assumed correct; their behavior is tested by +nixpkgs upstream, not by this repo. + +**Scenarios test custom logic only.** Examples of valid scenarios: + +- `database-backup-chain/` — io-guardian managed cross-host pg_dump +- `firewall-port-audit/` — custom networking module +- `io-guardian/` — custom io-guardian module +- `proxy-routing/` — custom proxy/caddy TLS routing +- `redis-remote-connect/` — custom redis module + +Auto-discovered per-host VM tests validate that **this repo's custom modules** work +correctly when composed with real production configurations. They are not unit tests +for nixpkgs services. + +Sops secrets are auto-discovered from `config.sops.secrets` — no manual secret name +maintenance is needed. + +## Two Test Authoring Modes + +### 1. Auto-Discovered Per-Host Tests + +Any server host automatically gets a `nixosTestConfigurations.` entry. The test +boots the host's full NixOS configuration with VM overrides applied and runs baseline +assertions: boot success, SSH availability, journald persistence, no failed units. + +To add service-specific tests to a host, use the existing `server.tests.units` option +in the host's configuration file. In `hosts/server/nixio/database.nix`: + +```nix +server.tests.units.postgres = { + testScript = { config, ... }: '' + nixio.succeed("sudo -u postgres psql -c 'SELECT 1'") + ''; +}; +``` + +The test runs inside a named Python `subtest` block in the VM test. The `testScript` +function receives the node's evaluated NixOS config as its argument. + +### 2. Explicit Scenario Tests + +For cross-service or multi-node interactions testing custom repository logic, create a +scenario file under `tests/scenarios//test.nix`. Each scenario defines arbitrary +NixOS nodes and a `testScript`. The directory name becomes the +`nixosTestConfigurations.` entry. + +Example (`tests/scenarios/proxy-routing/test.nix`): + +```nix +{ + nodes = { + nixio = { ... }; # caddy reverse proxy + nixcloud = { ... }; # nextcloud backend + }; + + testScript = '' + nixio.wait_for_unit("caddy.service") + nixcloud.wait_for_unit("phpfpm-nextcloud.service") + + with subtest("proxy routes to backend"): + out = nixio.succeed( + "curl -sf -H 'Host: nc.racci.dev' http://nixcloud/" + ) + assert "Nextcloud" in out, "proxy did not route to nextcloud" + ''; +} +``` + +Scenario tests automatically apply the VM test profile to every node and run baseline +assertions before the scenario-specific `testScript`. + +Guideline: use `server.tests.units` for single-service behavior verifiable inside one +VM. Use scenarios only when cross-service or multi-node interaction is required. + +## VM Test Profile + +The module at `tests/profiles/vm-test.nix` is injected into every VM test node. +It applies the overrides needed to make production server configs compatible with +QEMU VMs. + +### Disabled Services + +Services that need real external credentials are explicitly disabled in test VMs. +These services cannot validate in an isolated VM without real API keys or OAuth tokens. + +| Service | Reason | +| -------------------- | --------------------------------------------------------------- | +| `services.tailscale` | Needs a real auth key or OAuth client to join the tailnet | +| `services.mcpo` | Needs GitHub, AniList, and other OAuth tokens unavailable in CI | +| `services.ollama` | Requires GPU passthrough (ROCm/CUDA) unavailable in QEMU VMs | + +### ProxmoxLXC Overrides + +The test profile sets `proxmoxLXC.manageNetwork = false` and `proxmoxLXC.manageHostName = false`. +QEMU's test driver manages networking and hostname configuration for VM guests, so the +Proxmox LXC-specific flags are disabled to avoid conflicts. The remaining production +host configuration evaluates without modification. + +### Deterministic Sops Secrets + +Test VMs cannot use real sops decryption keys. Instead, the profile generates +deterministic dummy secrets using `systemd.tmpfiles.rules`. Each `sops.secrets.` +declared in a host configuration gets a file created at `config.sops.secrets..path` +with content derived from the secret key path: + +```nix +"test-${builtins.hashString "sha256" name}" +``` + +Key properties: + +- Same key path → identical content across all test nodes. Critical for shared secrets + (DB passwords, API keys shared between hosts) +- Different key paths → different values. Services depending on specific secrets can + validate path wiring correctness +- No real secret material enters the Nix store or repository +- `sops.placeholder.` and `sops.templates.` continue working. They return + deterministic placeholder values without real decryption keys + +The profile also sets `sops.age.keyFile = "/dev/null"` (satisfies sops-nix's eval-time +assertion that at least one key source exists), clears GnuPG key paths, and disables +sops file validation at build time. + +## Local Execution + +Build and run a single host's VM test: + +```bash +nix build .#nixosTestConfigurations. +``` + +```bash +nix build .#nixosTestConfigurations.nixio +``` + +List all available test targets: + +```bash +nix eval .#nixosTestConfigurations --apply 'builtins.attrNames' +``` + +### Filtering Specific Tests + +When debugging a single unit test, set `testFilter` to run only matching tests +instead of all `server.tests.units.*` entries for that host: + +```bash +nix build .#nixosTestConfigurations. \ + --override-input . '/path/to/this/repo?testFilter=postgres-connect' +``` + +Or by editing the flake-module locally: + +```nix +builder { + # ... + testFilter = [ "postgres-connect" ]; +} +``` + +`testFilter` is null by default (all tests run). When set to a list of strings, +only unit tests whose names appear in the list execute. Non-matching names are +silently skipped — baseline assertions still run. + +### Requirements + +- **`/dev/kvm`**: QEMU tests require KVM acceleration. Without it, tests are + impractically slow and may hang. +- **Nix**: Standard Nix with flake support. + +These tests are NOT run by `nix flake check`. + +## CI Behavior + +VM tests execute in a separate Woodpecker workflow (`.woodpecker/test-vm.yaml`): + +- **Trigger:** `pull_request` events only. Does not run on push, tag, or manual events. +- **Runner:** Requires a Woodpecker runner with the `kvm: true` label and `/dev/kvm` access. +- **Scope:** ALL server host VM tests run on every PR event. Affected-host selection + (building only hosts changed by a PR) is deferred to a future iteration. +- **Independence:** The `test-vm.yaml` workflow does not affect the existing + `check.yaml` workflow. A VM test failure does not block or alter `check.yaml` results. + +### Adding a New Test + +1. Decide on the test scope: + - **Single service, one host:** Add `server.tests.units.` to the service's + host configuration file. + - **Multi-node or cross-service:** Create a directory `tests/scenarios//` + with a `test.nix` file. +1. The test appears automatically in `nixosTestConfigurations` — no registration needed. +1. Run locally to verify: + ```bash + nix build .#nixosTestConfigurations. + ``` + +### Disabled Service Tests + +When a service is disabled by the VM test profile (e.g., `services.tailscale`), +its `server.tests.units` entries are silently skipped in per-host VM tests. +Disabled services cannot run, so their tests cannot pass. These services are +exercised by other means (integration tests on real infrastructure, manual validation). + +### Per-Service Test Patterns + +Component tests follow a layered testing strategy. The pattern varies by service type: + +#### HTTP Services (caddy, dashy, grafana, etc.) + +```nix +server.tests.units.minio = { + testScript = '' + nixio.succeed("curl -s http://localhost:9000/minio/health/live | grep -q 'ok'") + ''; +}; +``` + +#### Database Services (postgresql, redis, elasticsearch) + +```nix +server.tests.units.postgres-connect = { + testScript = '' + nixio.succeed("psql -U postgres -c 'SELECT 1'") + ''; +}; +``` + +For QEMU tests, use trust authentication — `vm-test.nix` injects `host all all all trust`. + +#### Systemd Units Only (services that can't start in QEMU) + +```nix +server.tests.units.clamav = { + testScript = '' + nixcloud.succeed("systemctl show clamav-daemon.service | grep -i loadstate") + ''; +}; +``` + +Services needing external credentials (Cloudflare, GitHub tokens, OAuth), GPU access, or hardware passthrough can't fully start in QEMU. Verify unit definition exists instead. + +#### Kernel/System Configs + +```nix +server.tests.units.kernel-forwarding = { + testScript = '' + nixio.succeed("sysctl -w net.ipv4.ip_forward=1") + nixio.succeed("sysctl -n net.ipv4.ip_forward | grep '^1$'") + nixio.succeed("sysctl -w net.ipv6.conf.all.forwarding=1") + nixio.succeed("sysctl -n net.ipv6.conf.all.forwarding | grep '^1$'") + ''; +}; +``` + +### Scenario Authoring Guidance + +Scenarios define self-contained NixOS nodes testing custom repository logic. Each node must work without external infrastructure. + +#### Naming + +- Directory name under `tests/scenarios//` becomes the `nixosTestConfigurations.` entry automatically +- Use kebab-case: `redis-remote-connect`, `database-backup-chain` + +#### Custom Logic Rule + +Scenarios MUST test custom modules from this repository, not upstream nixpkgs behavior. +A scenario that merely asserts "postgresql responds on port 5432" or "sshd has +PasswordAuthentication no" adds no value — that is nixpkgs upstream's responsibility. + +Valid scenario scope: + +- Cross-host interaction orchestrated by custom modules (io-guardian, proxy-routing) +- Custom module behavior (firewall-port-audit, database-backup-chain) +- Custom service integration (redis-remote-connect with repo's redis module) + +#### Self-Contained Rule + +Every service, secret, and dependency must be defined within the scenario nodes: + +- **PostgreSQL**: Use trust authentication (`host all all all trust`) — no sops secrets +- **Firewall**: Open ports explicitly with `networking.firewall.allowedTCPPorts` +- **DNS**: Use NixOS test driver hostnames (node names resolve automatically) +- **Secrets**: Avoid sops. Use inline configs, empty passwords, or trust auth + +#### Node Structure + +```nix +{ + nodes = { + server-node = { pkgs, ... }: { + services.openssh.enable = true; # baseline needs sshd + services.postgresql = { + enable = true; + enableTCPIP = true; + authentication = '' + local all all trust + host all all all trust + ''; + }; + networking.firewall.allowedTCPPorts = [ 5432 ]; + }; + client-node = { pkgs, ... }: { + environment.systemPackages = [ pkgs.postgresql ]; + }; + }; + testScript = '' + start_all() + # subtests here + ''; +} +``` + +#### What NOT to do + +- **Don't set `name`** — flake-module injects it from directory name +- **Don't import `vm-test.nix`** — builder handles that automatically +- **Don't reference `config.sops.secrets`** — no real secrets available +- **Don't use Cloudflare plugins in Caddy** — no API tokens +- **Don't expect GPU-accelerated services** — no GPU in QEMU +- **Don't test upstream nixpkgs behavior** — scenario tests are for custom logic only + +#### Multi-node Communication + +Nodes communicate via their NixOS test driver hostnames (the keys in `nodes`): + +```nix +# client-node reaches server-node: +client-node.succeed("psql -h server-node -U testuser -d testdb -c 'SELECT 1'") +``` + +IP assignment and DNS are handled automatically by the test driver.

Version 2 introduces a structural shift: VM tests no longer go under `checks` (which would trigger `nix flake check`). Instead they live under a new top-level flake attribute `nixosTestConfigurations`, parallel to `nixosConfigurations` and defined in the `nixos` partition. Adding a new top-level flake attribute requires updating `partitionedAttrs` in `flake/default.nix`. + +The codebase already has two testing infrastructures: + +- **`checks.cluster`** (in `flake/ci/flake-module.nix`): a multi-node test that imports all server hosts via `mkNode.nix`, boots them, and asserts they reach `multi-user.target`. This stays in `ci` — untouched. +- **`server.tests.units`** (in `modules/nixos/server/tests.nix`): an option tree where each host registers named test script functions. Currently consumed only by the cluster test, these become the auto-discovery source for per-host VM tests. + +The new design introduces a `nixosTestConfigurations` flake attribute that produces NixOS VM tests per host and per explicit scenario. Test code lives at root `tests/`. Services needing real API keys (Tailscale, MCPO, OAuth-based services) get disabled in VMs by policy.

Each entry is a NixOS configuration plus test module attachments, with schema `nixosTestConfigurations.` having `config`, `test`, and `passthru.requiredServices`. + +**Rationale:** Placing VM tests under `checks` would cause `nix flake check` to build and run them, which is too expensive and contrary to the plan. The `nixos` partition already owns `nixosConfigurations` — co-locating test configurations there keeps all host-derived NixOS eval in one partition. The existing `checks.cluster` stays in `ci` untouched. + +**Alternatives considered:** + +- Add `vm-test-` checks to the `ci` partition: would require moving host config eval into `ci` or cross-partition referencing, adding complexity. +- Keep under `checks`: triggers on `nix flake check`, violates the plan. + +### Decision 2: VM test profile (`tests/profiles/vm-test.nix`) + +**Choice:** A single NixOS module injected into every VM test node that applies the following policy: + +- **DISABLED (mkForce false):** services needing real external API keys or outbound auth — `services.tailscale.enable`, `services.mcpo.enable`, any OAuth-dependent services (identified by their sops OAuth secret references). +- **DISABLED (mkForce false):** GPU-dependent services — `services.ollama.enable` (covers nixai's ROCm/ollama). +- **OVERRIDDEN:** `proxmoxLXC.manageNetwork = false`, `proxmoxLXC.manageHostName = false` — avoids QEMU test driver network conflicts without preventing eval. +- **GENERATED:** `sops.age.keyFile = "/dev/null"`, `sops.gnupg.home = null`, `sops.gnupg.sshKeyPaths = []`, `sops.validateSopsFiles = false`, and `systemd.tmpfiles.rules` entries that write deterministic content `"test-${builtins.hashString "sha256" name}"` to each `config.sops.secrets..path`. For `format = "binary"` secrets the same hex-encoded hash is written (no special binary handling needed — the consumer gets consistent deterministic data). This satisfies path wiring without real decryption keys. + +**Rationale:** The plan rejects modifying host configs under `hosts/server/*` just to make tests pass. A single injected profile contains the compatibility layer in one place, is version-controlled alongside tests, and is easy to audit. + +**Alternatives considered:** + +- Remove LXC assumptions from production hosts: too invasive for a testing feature. +- Disable secret-dependent modules entirely: reduces coverage vs. generating path-verified dummy values. +- Maintain per-service override lists in CI config: harder to reason about than a centralized policy module. + +**Note:** sops-nix `sops.placeholder.` and `sops.templates.` work automatically in the VM test profile — they return deterministic values when no real keys are available, so no special handling is needed for downstream consumers (MCPO, monitoring, etc.). + +### Decision 3: Two test authoring modes — auto-discovered and explicit + +**Choice:** + +- **Auto-discovered:** For each host in `nixosTestConfigurations.`, harvest `config.server.tests.units` from the evaluated config. These are the same test function hooks already in the codebase. The existing `server.tests` module (`modules/nixos/server/tests.nix`) is the source of truth — no migration needed. +- **Explicit scenarios:** Files under `tests/scenarios//test.nix` that define NixOS nodes + test script. + +**Rationale:** Auto-discovery keeps the framework host-agnostic and avoids brittle hostname lists. Explicit scenarios fill the gap for multi-node or cross-cutting custom logic that isn't captured by per-host unit tests. + +**Testing philosophy — custom logic only:** Scenarios exist only to validate **this repo's custom modules**, not upstream nixpkgs behavior. nixpkgs services (postgresql, openssh, prometheus, pgvector) are assumed correct. A scenario that tests basic upstream functionality (e.g., "does postgresql accept connections?") provides no value and should not be added. Keep: `database-backup-chain`, `firewall-port-audit`, `io-guardian`, `proxy-routing`, `redis-remote-connect`. Delete any scenario testing nixpkgs baseline behavior. + +**Sops secrets are auto-discovered:** The VM test profile reads `config.sops.secrets` and generates deterministic dummy files for every entry. No manual secret name maintenance is needed — if a module declares a secret, it gets a test value. + +**Alternatives considered:** + +- Only auto-discovered: misses cross-host integration scenarios. +- Only explicit: duplicates what `server.tests.units` already provides. +- Read scenario names from a registry file: unnecessary indirection; filesystem discovery via `builtins.readDir` is sufficient. + +### Decision 4: Create `tests/builder.nix` as the builder + +**Choice:** `tests/builder.nix` becomes the new VM test builder function accepting either a hostname (auto-discovered mode) or a scenario attribute set (explicit mode). It returns a NixOS test derivation compatible with `pkgs.testers.runNixOSTest`. The output is registered in `nixosTestConfigurations.` by the nixos partition module. `tests/default.nix` (the existing cluster test) remains unchanged. + +**Rationale:** Reuses the existing test infrastructure pattern while keeping the existing cluster test (`tests/default.nix`) untouched. The existing `mkNode.nix` is repurposed for host-based tests. Scenario tests define their own nodes. + +**Alternatives considered:** + +- Extend `tests/default.nix` instead: would modify the existing cluster test file, violating the server-vm-test-harness spec constraint that `tests/default.nix` SHALL NOT be modified. +- Inline test construction in the flake module: couples flake structure to test logic. + +### Decision 5: Woodpecker PR gating in a new workflow + +**Choice:** New `.woodpecker/test-vm.yaml` workflow. Only runs on `pull_request` events. Uses KVM-capable runners (label `kvm: true`). Builds `nixosTestConfigurations.*` targets with `nix build .#nixosTestConfigurations..test` for **all** server hosts (per-host pass/fail reporting). Does NOT touch the existing `.woodpecker/check.yaml` which continues to build `checks.cluster`. Affected-host selection (building only tests for hosts modified by the PR) is deferred to a future iteration. + +**Rationale:** Separates VM test execution from the main check workflow. PR-only avoids running expensive VM tests on every push to master. KVM gating prevents silent failures on runners without virtualization support. + +**Alternatives considered:** + +- Add VM test step to existing `check.yaml`: risks slowing down the fast feedback loop for non-VM checks. +- Run on every push: unnecessarily expensive for master commits that passed PR checks. + +### Decision 6: Secret policy — tmpfiles-based deterministic secrets + +**Choice:** Rather than setting `sops.secrets..value` (which sops-nix does not support), the VM test profile: + +1. **Imports sops-nix** so `sops.secrets.` option declarations exist for all host secrets. +2. **Sets `sops.validateSopsFiles = false`** — prevents sops from erroring at build time about missing or unreadable `.sops` files. +3. **Sets `sops.age.keyFile = "/dev/null"`**, `sops.gnupg.home = null`, `sops.gnupg.sshKeyPaths = []` — satisfies sops-nix's eval-time assertion that at least one key source is configured, while providing no real keys. The key file is never used because tmpfiles secrets are already in place. +4. **Uses `systemd.tmpfiles.rules`** to create each secret file at runtime at `config.sops.secrets..path` with mode/permissions matching the secret's owner/group settings and content `"test-${builtins.hashString "sha256" name}"`. For `format = "binary"` secrets the same hex-encoded hash is written (no special binary handling needed). + +This produces runtime files at the expected paths (`/run/secrets/` by default) so services that read `config.sops.secrets..path` find a valid file. + +**Rationale:** Satisfies sops-dependent modules that read `config.sops.secrets..path` without needing real encrypted files or decryption keys. The hash is deterministic, so rebuilds are cacheable. Cross-server consistency is guaranteed because the value depends only on the secret name. + +**Alternatives considered:** + +- Disable all sops-dependent modules: reduces test coverage significantly. +- Commit encrypted dummy files to the repo: adds maintenance burden and risks confusion with production secrets. +- Use `sops.testing` hooks: over-engineered for a wiring-validation concern. + +### Decision 7: Service disablement policy (explicit categories) + +**Choice:** The VM test profile documents three categories of service handling: + +| Category | Action | Examples | Rationale | +|---|---|---|---| +| **DISABLED** | `mkForce false` | Tailscale, MCPO, OAuth-dependent services | Need real external API keys or auth flows unavailable in CI | +| **DISABLED** | `mkForce false` | ollama, ROCm services | Require GPU hardware unavailable in QEMU VMs | +| **OVERRIDDEN** | `mkForce false` on specific options | `proxmoxLXC.manageNetwork`, `proxmoxLXC.manageHostName` | Would interfere with QEMU test driver networking; eval is still valid | +| **GENERATED** | Tmpfiles writes deterministic hash content at secret path (hex-encoded for binary secrets) | All `sops.secrets.` | Validates path wiring without real secret material | + +**Rationale:** Explicit categorization makes the coverage gap visible and auditable. Engineers can see at a glance what is and isn't tested. + +## Risks / Trade-offs + +**[KVM availability]** → VM test throughput and reliability depend on Woodpecker runners exposing `/dev/kvm`. Without KVM, tests will be extremely slow or may hang. +*Mitigation:* Gate the workflow with a `kvm: true` runner label. Document the requirement. Fail fast if `/dev/kvm` is unavailable. + +**[LXC mismatch (minimal)]** → The VM test profile overrides `proxmoxLXC.manageNetwork` and `proxmoxLXC.manageHostName` to false. Remaining LXC-specific behavior (e.g., `core.generators.proxmoxLXC.enable`) may still eval but should not block boot. +*Mitigation:* Centralize overrides in `tests/profiles/vm-test.nix` and expand incrementally as incompatibilities are discovered. The impact is minimal because the overrides target the specific options known to conflict with QEMU. + +**[Secret fidelity gap]** → Deterministic tmpfiles-based secrets validate path wiring, not real secret values. A module that reads a secret and uses it for a cryptographic operation will get a garbage value in the VM. +*Mitigation:* Treat this framework as pre-deploy structural validation, not a substitute for runtime production secret correctness. Services that require real secrets to function are in the DISABLED category and won't be tested. + +**[Service coverage gap]** → Because API-key-dependent services (Tailscale, MCPO, OAuth) are disabled, they are not tested in VMs. +*Mitigation:* Accept as a documented gap. These services are exercised by other means (integration tests on real infra, manual validation). The auto-discovered `server.tests.units` may still contain useful config-level assertions for these services that run without the service being enabled (e.g., "validate that the config file would be syntactically correct"). + +**[Build time]** → VM tests are expensive to build. Adding one per host plus scenarios significantly increases CI build time. +*Mitigation:* Use `nix-fast-build` or similar caching strategies. The Woodpecker workflow is PR-only, not on every push. Consider affected-host selection in a future iteration. + +**[mkForce collision]** → The VM test profile uses `mkForce false` on `services.tailscale.enable`, `services.mcpo.enable`, and `services.ollama.enable`.
