olla-validate

Testing & Quality
View on GitHub

Full automated validation of Olla via parallel agents against mock backends (no Docker, no real LLMs - CI/CD safe). Gates on make ready first, then boots an ollamock fleet + Olla and fans out per-area validation agents covering core routing, OpenAI/Anthropic surfaces, observability, health/recovery and failure handling. Use as the pre-release gate or after major changes. Trigger when the user asks to validate Olla, run the validation suite, run regression/nightly validation, or gate a release. Runs on Sonnet regardless of the session model; area agents are balanced between Sonnet and Haiku for token efficiency.

/olla-validate - Olla Validation Harness

One reusable suite, two depths:

ModeTarget timeScope
--quick5–10 minmake ready gate + live smoke of every area (trimmed checklists)
--nightly2–4 hfull test suite + stress + exhaustive checklists + chaos + soak + sherpa pass + translation-forced pass + bench snapshot

If neither flag is given, ask with AskUserQuestion: "Which validation depth?" - options Quick (Recommended after major changes) (5–10 min smoke gate) and Nightly (multi-hour exhaustive pre-release gate). --soak-minutes=N overrides the nightly soak duration (default 30).

The harness never touches real backends. All traffic goes to test/cmd/ollamock instances (stdlib Go mock speaking OpenAI, Ollama-native, LM Studio, Lemonade and Anthropic protocols, with a /_mock/ fault-injection control plane).

Model assignment (token efficiency)

The orchestration runs on Sonnet (model: sonnet above) - it makes the judgement calls, sequences nightly passes and writes the report. Subagents cannot spawn subagents, so orchestration must stay here; never try to delegate the whole run to a single agent.

Spawned area agents get an explicit model on every Agent call:

  • haiku - mechanical curl-and-assert checklists that never mutate state: core-routing, openai-api, observability, limits-failures (client section).
  • sonnet - anything that mutates mock/Olla state or needs protocol- sequence judgement: resilience, anthropic (both sections - SSE event-order and translation validation), limits-failures (upstream section).

Escalation rule: if a Haiku agent returns malformed report JSON, dies, or its failures look like agent error rather than product error (e.g. it asserted the wrong endpoint set), re-run that one area once on Sonnet before trusting a FAIL. Record the escalation in the report.

Topology (fixed ports)

One ollamock instance per endpoint - Olla keys endpoint identity on the URL, so endpoints sharing a URL silently collapse to one (last declared wins).

Mock fault injection: POST http://127.0.0.1:194NN/_mock/behaviour with {"mode":"ok|error|flaky|hang|slow","error_status":503,"error_rate":0.5,"latency_ms":0,"fail_health":false,"drop_mid_stream":false,"malformed_json":false}; POST /_mock/reset restores defaults; GET /_mock/stats gives per-path request counts. See test/cmd/ollamock/README.md.

Phase 0 - Setup

MODE=quick|nightly                  # from args or AskUserQuestion
SOAK_MINUTES=${SOAK_MINUTES:-30}    # nightly only
RUN_TS=$(date -u +%Y%m%d-%H%M%S)
GIT_SHA=$(git rev-parse --short HEAD)
RESULTS=test/results
REPORT=$RESULTS/olla-validate-$RUN_TS.md
LOGDIR=$RESULTS/logs/olla-validate-$RUN_TS
mkdir -p "$LOGDIR"

Check ports 19431–19437, 41141–41142 are free (netstat -ano | grep <port> or curl probe); if occupied, kill stale ollamock/olla-validate processes from a previous run, otherwise abort with a clear message.

Track every PID you start. Teardown (Phase 7) must always run, including on abort.

Phase 1 - Static gate (fail fast)

Both modes:

make ready 2>&1 | tee "$LOGDIR/make-ready.log"

Nightly additionally:

make test        2>&1 | tee "$LOGDIR/make-test.log"
make test-stress 2>&1 | tee "$LOGDIR/make-test-stress.log"

Any failure here → abort: skip the live phases, go straight to Phase 8 and write a FAILED report quoting the failing output. Do not "fix and continue" - this skill is a gate, not a repair loop. Report failures; the user decides.

Phase 2 - Build

EXE=$(go env GOEXE)
go build -o "build/validate/olla$EXE" .
go build -o "build/validate/ollamock$EXE" ./test/cmd/ollamock

Phase 3 - Boot the fleet

Start each process with the Bash tool in background mode, logging to $LOGDIR:

build/validate/ollamock$EXE --addr 127.0.0.1:19431 --name mock-a --models "test-model,shared-model"   > "$LOGDIR/mock-a.log" 2>&1
build/validate/ollamock$EXE --addr 127.0.0.1:19432 --name mock-b --models "test-model,beta-model"     > "$LOGDIR/mock-b.log" 2>&1
build/validate/ollamock$EXE --addr 127.0.0.1:19433 --name mock-c --models "llama3.1:8b,shared-model"  > "$LOGDIR/mock-c.log" 2>&1
build/validate/ollamock$EXE --addr 127.0.0.1:19434 --name mock-d --models "phi-4,shared-model"        > "$LOGDIR/mock-d.log" 2>&1
build/validate/ollamock$EXE --addr 127.0.0.1:19435 --name mock-e --models "test-model,shared-model"   > "$LOGDIR/mock-e.log" 2>&1
build/validate/ollamock$EXE --addr 127.0.0.1:19436 --name mock-f --models "test-model,beta-model"     > "$LOGDIR/mock-f.log" 2>&1
build/validate/ollamock$EXE --addr 127.0.0.1:19437 --name mock-g --models "phi-4,shared-model"        > "$LOGDIR/mock-g.log" 2>&1
build/validate/olla$EXE --config test/validate/config.validate.yaml        > "$LOGDIR/olla-main.log" 2>&1
build/validate/olla$EXE --config test/validate/config.validate.limits.yaml > "$LOGDIR/olla-limits.log" 2>&1

Readiness gates (poll up to 60s, 1s interval; abort to teardown on timeout):

  1. Each mock: curl -sf http://127.0.0.1:194NN/health
  2. Olla main: curl -sf http://127.0.0.1:41141/internal/health
  3. Olla limits: curl -sf http://127.0.0.1:41142/internal/health
  4. All 7 endpoints healthy: poll /internal/status/endpoints until every entry reports healthy/routable
  5. Model discovery done: poll /olla/models until it lists shared-model

Record boot time in the report. If any process dies during boot, capture the tail of its log into the report.

Phase 4 - Wave 1: parallel happy-path agents

Spawn five agents in parallel (single message, multiple Agent calls, subagent_type: general-purpose, model per the table below). Each agent prompt must contain:

  • The mode (quick or nightly) and instruction to execute the matching checklist in its area file (path below) - read the file first.
  • The topology table above (URLs, ports, which mock backs which endpoint).
  • The reporting contract: "Return ONLY a JSON object: {"area":"<name>","pass":N,"fail":N,"warn":N,"skip":N,"failures":[{"check":"","expected":"","actual":"","evidence":""}],"warnings":[...],"notes":""}. Every checklist item is exactly one of pass/fail/warn/skip. Use warn for behaviour that works but looks off; never silently skip - record skips with a reason in notes. Do not modify any repo files. Do not kill or restart any process. Do not call any /_mock/behaviour endpoint unless your area file explicitly says to."
AgentArea fileModel

limits-failures (client section - 41142 only).claude/skills/olla-validate/areas/limits-failures.mdhaiku

Wave 1 agents are read-only against the mocks: no fault injection, so they can run concurrently without poisoning each other's assertions.

Phase 5 - Wave 2: resilience agent (solo)

After wave 1 completes, POST /_mock/reset to all seven mocks (ports 19431-19437), confirm all endpoints healthy again, then spawn one agent (model: sonnet) for .claude/skills/olla-validate/areas/resilience.md (mode-appropriate checklist). This agent is allowed to inject faults via /_mock/behaviour and (nightly) to ask you to kill/restart a mock - for process kill/restart steps the agent reports back what it needs and you perform the kill/restart yourself, or simpler: give the agent the PID table and let it use taskkill/kill itself, then verify afterwards that all seven mocks are running again (restart any that are not, from the same command lines as Phase 3).

After wave 2: reset all mock behaviours, re-confirm all endpoints return to healthy within 60s (this is itself a recovery assertion - record it; health probes tick globally every 30s regardless of per-endpoint check_interval).

Phase 6 - Nightly-only extended passes (sequential)

Skip this phase entirely in quick mode.

6a. Upstream-failure section of limits-failures

Spawn the limits-failures agent again (model: sonnet - it mutates mock-a behaviour), pointing it at the upstream section of its area file (runs solo). Reset mocks after.

6b. Translation-forced Anthropic pass

sed 's/passthrough_enabled: true/passthrough_enabled: false/' \
  test/validate/config.validate.yaml > "$LOGDIR/config.translation.yaml"

Restart olla-main with that config, wait for readiness (Phase 3 gates 2/4/5), zero mock stats (POST /_mock/reset on all), then spawn the anthropic agent (model: sonnet) against the translation-forced section of its area file. Restart olla-main on the original config afterwards and re-confirm readiness.

6c. Sherpa engine pass

sed 's/engine: "olla"/engine: "sherpa"/' \
  test/validate/config.validate.yaml > "$LOGDIR/config.sherpa.yaml"

Restart olla-main on it, wait for readiness, then run quick checklists of core-routing, openai-api and anthropic (passthrough) - three parallel agents (haiku, haiku, sonnet respectively, as in wave 1). Sherpa is maintenance-mode: quick depth is deliberate. Restore the original config and readiness afterwards.

6d. Soak + chaos

Run for $SOAK_MINUTES minutes against olla-main (olla engine, original config):

  • Background load: a loop issuing ~5 req/s mixed traffic (non-stream chat, streaming chat, anthropic messages, /olla/models) - a small bash loop is fine; log status-code counts.
  • Every 60s sample /internal/process (goroutines, heap) to $LOGDIR/soak-samples.jsonl.
  • Chaos: every ~3 minutes pick one mock, inject fail_health or mode=error, hold for 60s, then reset. (Health probes tick globally every 30s, so shorter faults may never be observed by the checker.) Never fault more than one mock at a time, and never mock-a and mock-b simultaneously (they are the only openai-compatible-typed pair).

Pass criteria: zero client-visible 5xx for requests issued while at least one compatible backend was healthy and un-faulted (allow a small transition window of ≤5s after each injection); goroutine count at end within 25% of the pre-soak baseline after a 60s settle; heap not monotonically growing across the final third of samples. Anything outside → FAIL with the samples quoted.

6e. Bench snapshot

make bench-balancer 2>&1 | tee "$LOGDIR/bench-balancer.log"

Record results in the report (informational - WARN if any benchmark fails to run, never FAIL on numbers).

Phase 7 - Teardown (always)

Kill every started PID (olla instances first, then mocks). On Windows Git Bash, kill <pid> works for processes you started; fall back to taskkill //F //PID <pid> if needed. Verify ports are released. Remove build/validate/ binaries only if the user's tree was clean of them before.

Phase 8 - Report & verdict

Aggregate every agent JSON plus the phase-level checks you performed yourself (gates, boot, recovery-after-reset, soak) into $REPORT:

# Olla Validation - <mode> - <RUN_TS>
- Commit: <GIT_SHA>  Branch: <branch>  Engine passes: olla[, sherpa]
- Verdict: PASS | FAIL
- Totals: P/F/W/S

| Area | Pass | Fail | Warn | Skip |
|---|---|---|---|---|
...

## Failures
<one block per failure: check, expected, actual, evidence>

## Warnings / Notes / Soak samples summary / Bench snapshot

Append one line to $RESULTS/last-runs.md (create with a header if missing):

<UTC date time> | olla-validate (<mode>) | PASS|FAIL | <P>P/<F>F/<W>W | <GIT_SHA> | report:<REPORT path>

Verdict rule: any FAIL anywhere (including the Phase 1 gate, boot, soak or a dead agent) → overall FAIL. Warnings never fail the gate but must all appear in the report. Finish by telling the user the verdict, the totals, the three most important findings in plain sentences, and the report path.
