testing

Testing guidance for a memory-service codebase, with an emphasis on Cucumber-based behavior-driven development (BDD) tests. Cucumber describes expected behavior as user-readable scenarios, while the guidance also covers failure logs and isolated test users.

In plain words
What is it for?
Use it when writing or debugging REST and gRPC tests, investigating failed Cucumber scenarios, or checking user isolation in protobuf-based test requests.
Why use it?
It helps developers choose the right kind of test and diagnose failures without confusing test users or producing misleading database errors.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

testing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Testing Guidelines

Prefer Cucumber for API Testing

For REST and gRPC tests, use the Go BDD suite under internal/bdd/testdata/features*/ instead of unit tests with mocks.

Reserve unit tests with mocks for internal implementation details and infrastructure testing.

Cucumber Failure Reporting

When tests fail:

go test ./internal/bdd -run TestFeatures... > test.log 2>&1
rg -n "FAIL|ERROR|panic|--- FAIL:" test.log

Prefer searching the redirected log for the failing scenario and stack trace context.

Canonical User Isolation

The gRPC text-protobuf helper rewrites quoted canonical users such as "alice" to scenario-isolated IDs. When production authentication metadata must match a user ID embedded in a protobuf body (for example user/<id> memory namespaces), set the metadata from TestScenario.IsolatedUser rather than using a literal canonical name.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

testing is a skill published in the GitHub repository chirino/memory-service (11 stars, last pushed 5d ago), licensed Apache-2.0. It adds 22 tokens to every session and 222 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
