e2e-testing

An AI-controlled end-to-end testing tool for checking an app through its visible interface. End-to-end testing means testing a complete user flow, such as opening a screen, entering text, and verifying the result.

In plain words
What is it for?
Use it to take screenshots, tap controls, type, scroll, inspect the app's UI structure, navigate flows, and verify state in Flutter, React Native, iOS, Android, Electron, Tauri, KMP, or .NET MAUI apps.
Why use it?
It lets an agent inspect and operate a running app without requiring test code for each interaction. This helps check whether the interface behaves correctly across supported app platforms.

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 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.

AI E2E Testing — 8 Platforms, Zero Test Code

flutter-skill is an MCP server that connects AI agents to running apps across 8 platforms. The agent takes screenshots, taps elements, enters text, scrolls, navigates, inspects UI trees, and verifies state — all through natural language.

Supported Platforms

Platform Setup
Flutter (iOS/Android/Web) flutter pub add flutter_skill
React Native npm install flutter-skill-react-native
Electron npm install flutter-skill-electron
iOS (Swift/UIKit) SPM: FlutterSkillSDK
Android (Kotlin) Gradle: flutter-skill-android
Tauri (Rust) cargo add flutter-skill-tauri
KMP Desktop Gradle dependency
.NET MAUI NuGet package

Install

# npm (recommended)
npm install -g flutter-skill

# Homebrew
brew install ai-dashboad/flutter-skill/flutter-skill

# Or download binary from GitHub Releases

MCP Configuration

Add to your AI agent's MCP config (Claude Desktop, Cursor, Windsurf, OpenClaw, etc.):

{
  "mcpServers": {
    "flutter-skill": {
      "command": "flutter-skill",
      "args": ["server"]
    }
  }
}

Quick Start

1. Initialize your app (one-time)

flutter-skill init

Auto-detects project type and patches your app with the testing bridge.

Verify: Output should confirm the project type was detected and main entry point was patched. If it fails, check that you are in the project root and the framework is supported.

2. Launch and connect

flutter-skill launch .

Verify: A VM Service URI appears in the output (e.g. ws://127.0.0.1:50000/ws). If no URI appears, check that Flutter/the target framework is installed and the app compiles.

3. Test with natural language

The agent follows this core loop:

  1. screenshot() — see the current screen
  2. inspect_interactive() — discover all tappable/typeable elements with semantic refs
  3. tap(ref: "button:Login") — tap using stable semantic reference
  4. enter_text(ref: "input:Email", text: "[email protected]") — type into field
  5. wait_for_element(key: "Dashboard") — verify navigation succeeded
  6. screenshot() — confirm final state

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 ai-dashboad/flutter-skill (362 stars, last pushed 12d ago), licensed MIT. It adds 107 tokens to every session and 1,508 once invoked, about $0.0005 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 2026-08-30.
