e2e-testing

e2e-testing is a skill for Claude Code from CrowdStrike/foundry-skills. It costs 116 tokens per session (5,263 once invoked), scanned A, original, MIT.

A guide to end-to-end testing for CrowdStrike Falcon Foundry apps using Playwright. End-to-end tests operate an app as a user would, checking that its full interface and connected behaviour work together.

In plain words
What is it for?
Adding Playwright tests, configuring authentication and app installation, and testing Foundry pages and workflows through browser-based scenarios.
Why use it?
It provides the project setup and testing structure needed to verify an app beyond isolated code units.

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-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 21d 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.

Foundry E2E Testing

End-to-end testing for Falcon Foundry apps using Playwright and the @crowdstrike/foundry-playwright library.

The library provides authentication, app install/uninstall, page objects, and configuration so each app only writes its app-specific tests.

Part of a suite. If development-workflow has not already run, and this is a new app or its first capability, load the development-workflow skill first — it owns the CLI prerequisite check, scaffolding order, and manifest coordination.

Quick Start

1. Create the e2e/ directory

my-foundry-app/
├── e2e/
│   ├── .env                    # Local credentials (git-ignored)
│   ├── .env.sample             # Template for other developers
│   ├── .gitignore
│   ├── package.json
│   ├── playwright.config.ts
│   └── tests/
│       └── foundry.spec.ts
├── manifest.yml
└── ...

2. package.json

Node.js LTS is recommended.

{
  "name": "playwright-foundry",
  "version": "1.0.0",
  "scripts": {
    "test": "npx playwright test",
    "test:ui": "npx playwright test --ui",
    "test:debug": "npx playwright test --debug",
    "test:verbose": "DEBUG=true npx playwright test --reporter=list"
  },
  "type": "commonjs",
  "devDependencies": {
    "@crowdstrike/foundry-playwright": "0.5.0",
    "@types/node": "25.6.0"
  }
}

Always pin exact versions — never use "latest", "^", or "~". Check npm for the current version of each package.

The library brings @playwright/test, @dotenvx/dotenvx, and otpauth as transitive dependencies. No need to install them separately.

3. .env

[email protected]
FALCON_PASSWORD=your-password
FALCON_AUTH_SECRET=your-totp-secret
FALCON_BASE_URL=https://falcon.us-2.crowdstrike.com
APP_NAME=your-app-name

Convention for sample apps: Set APP_NAME to match the manifest name field, which should match the repo name (e.g., foundry-sample-functions-python). This avoids spaces in names and simplifies CI. This is a convention, not a hard requirement.

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.

e2e-testing is a skill published in the GitHub repository CrowdStrike/foundry-skills (35 stars, last pushed today), licensed MIT. It adds 116 tokens to every session and 5,263 once invoked, about $0.0005 per session on Opus 5.5. 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.
