testing-standards

A set of rules for writing tests in Compozy's Go codebase. It requires specific test structure, the Testify testing library, and standard ways to create mocks.

In plain words
What is it for?
Use it when adding or reviewing Compozy Go tests, especially table-style tests using t.Run, Testify assertions, and mocks.
Why use it?
It prevents different testing styles from being mixed together and makes tests easier to review and maintain. It also explicitly rules out suite-based tests and related lifecycle methods.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 26 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,772 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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-standards 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.

Anti-Patterns to Avoid

<anti_patterns type="prohibited_patterns"> NEVER USE TESTIFY SUITE PATTERNS:

  • PROHIBITED: suite.Suite embedding or any suite-based test structures
  • PROHIBITED: Suite methods like s.Equal(), s.NoError(), s.True(), s.False(), s.T()
  • PROHIBITED: testsuite.WorkflowTestSuite or similar suite embeddings
  • PROHIBITED: Suite lifecycle methods like SetupTest(), TearDownTest(), AfterTest()

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-standards is a cursor rule published in the GitHub repository compozy/gograph (9 stars, last pushed 1y ago), licensed MIT. It adds 26 tokens to every session and 1,772 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 2026-08-31.
