e2e-test-suite-init

e2e-test-suite-init is a skill for Claude Code from agentmantis/test-skills. It costs 82 tokens per session (1,033 once invoked), scanned A, original, MIT.

A workflow for setting up a complete Playwright end-to-end test suite in a project. It creates the test folders, configuration, shared page class, fixtures, authentication setup, and environment settings.

In plain words
What is it for?
Use it to initialise Playwright testing for a new project, including browser configuration, reusable test helpers, saved login state, page objects, and test directories.
Why use it?
It removes the repeated setup work required before a project can start writing browser tests. It also establishes a consistent structure for handover, regression, and smoke tests.

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

e2e-test-suite-init 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Initialise E2E Test Suite

Scaffold the entire e2e/ directory structure with all configuration files, base classes, fixtures, and helpers needed to start writing Playwright E2E tests.


Pre-Flight Check

  1. Check if e2e/ already exists. If so, abort and inform the user — do NOT overwrite an existing test suite.
  2. Check if Playwright is installed. If @playwright/test is not in package.json, add it.

Workflow

Step 1 — Create the Directory Structure

e2e/
├── auth/
│   └── auth.setup.ts
├── fixtures/
│   └── base.ts
├── helpers/
│   └── env-config.ts
├── poms/
│   └── base.page.ts
├── test-data/
├── tests/
│   ├── handover/
│   ├── regression/
│   └── smoke/
├── .auth/                   # git-ignored, holds saved session state
├── .gitignore
├── .env.example
├── playwright.config.ts
└── tsconfig.json

Step 2 — Generate Configuration Files

Generate each file using the reference templates:

File Template Reference
playwright.config.ts references/playwright-config-template.md
poms/base.page.ts references/base-page-template.md
fixtures/base.ts references/fixtures-template.md
helpers/env-config.ts references/env-config-template.md
auth/auth.setup.ts See e2e-test-conventions skill, references/auth-setup.md

Step 3 — Generate Support Files

e2e/.gitignore:

.auth/
.env
.env.*
!.env.example
test-results/
playwright-report/
blob-report/

e2e/.env.example:

BASE_URL="https://your-app.example.com"
LOGIN_EMAIL="[email protected]"
LOGIN_PASSWORD="your-password"
AUTH_FILE="e2e/.auth/user.json"

e2e/tsconfig.json:

{
    "compilerOptions": {
        "target": "ES2022",
        "module": "commonjs",
        "moduleResolution": "node",
        "strict": true,
        "esModuleInterop": true,
        "skipLibCheck": true,
        "forceConsistentCasingInFileNames": true,
        "resolveJsonModule": true,
        "outDir": "./dist",
        "rootDir": "."
    },
    "include": ["**/*.ts"],
    "exclude": ["node_modules", "dist"]
}

Files

What ships with it

4 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.
