test-standards

test-standards is a skill for Claude Code, Codex from idavidov13/agentic-playwright. It costs 166 tokens per session (3,481 once invoked), scanned A, original, MIT.

A set of conventions for writing Playwright tests, a tool that controls web browsers to check applications. It covers test structure, labels, test types, data, assertions, and cleanup.

In plain words
What is it for?
Use it when creating or reviewing browser tests, including smoke, regression, API, end-to-end, and setup tests.
Why use it?
It keeps tests consistent and reduces unreliable checks, shared-state problems, and leftover test data.

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

test-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.

Test Standards

Critical

  • Imports: Import test and expect from fixtures/pom/test-options.ts. NEVER from @playwright/test in spec files.
  • Single-tag rule: Each test has exactly one tag chosen from @smoke | @sanity | @regression | @e2e | @api | @destructive. NEVER combine tags. NEVER use @functional. NEVER put tags on test.describe() blocks.
  • @destructive is the heaviest tag and always wins — but only for shared/global state. A test that mutates state other tests or users depend on (locale, permissions, roles, guest access, feature flags, global settings) is tagged only @destructive. A test that creates and deletes only its own data is isolated, not destructive — tag it by importance (@smoke / @sanity / @regression / @e2e / @api).
  • Every state-mutating test must have test.afterEach() or test.afterAll() cleanup that reverts the change — both @destructive shared-state tests and isolated tests that write their own data.
  • Web-first assertions only (await expect(locator).toBeVisible(), .toHaveText(), .toBeEnabled(), .toHaveCount(...), etc.). NEVER page.waitForTimeout(...).
  • Use test.step() for Given/When/Then structure when a test has more than one distinct phase (setup, action, assertion).
  • Tests must be independent. No ordering dependencies, no shared mutable state across tests.
  • NEVER commit explore-only or debug test files (.spec.ts containing console.log(await page.content()), temporary probes, etc.).
  • Static test data is imported from .ts modules (test-data/static/**/*.ts) via named as const exports. NEVER .json.
  • Dynamic happy-path data comes from Faker factories (test-data/factories/{area}/); universal type-mismatch arrays from test-data/static/util/invalid-values.ts; domain-specific curated sets from test-data/static/{area}/*.ts. See the data-strategy skill.
  • Page objects are consumed via the fixture (async ({ appPage }) => ...). NEVER new PageObject(page) inside a test.
  • After adding or modifying a test file, run the affected tests and confirm zero failures before finishing the task.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
