testing-standards

testing-standards is a cursor rule for Cursor from floriscornel/todo-mcp. It costs 248 tokens per session, scanned A, original, MIT.

A set of testing rules for a JavaScript or TypeScript project using Vitest, including test structure, naming, database setup, cleanup, mocking, and coverage requirements. Code coverage measures how much of the code tests execute.

In plain words
What is it for?
Use it to write and organise Vitest tests, test database-backed code, manage test data and mocks, clean up after tests, and run coverage checks.
Why use it?
It gives the team a shared testing standard and helps prevent tests from interfering with one another or missing important code paths.

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 5d 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 Standards

Coverage Requirements

  • Minimum 80% coverage for branches, functions, lines, and statements
  • Use npm run test:coverage to run tests with coverage reporting
  • Coverage reports available in coverage/ directory

Test Structure

  • Follow the existing test patterns in src/__tests__/
  • Use Vitest with globals enabled
  • Test database setup in src/test-utils/vitest.setup.ts

Database Testing

  • Use TEST_DATABASE_URL environment variable for test database
  • Tests should be isolated and not affect each other
  • Clean up test data after each test

Test Naming

  • Describe what the test does: should create task with valid data
  • Group related tests with describe blocks
  • Use beforeEach/afterEach for setup/cleanup

Mock Patterns

  • Mock external dependencies consistently
  • Use Vitest's built-in mocking capabilities
  • Avoid mocking internal functions unless necessary

Test Data

  • Create meaningful test data that represents real usage
  • Use factories or builders for complex test objects
  • Keep test data minimal but realistic
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.
