🧪 Jestty

A faster, leaner, and optimized Jest runner.

jestty is a drop-in replacement for running Jest tests, with performance optimizations and a simpler workflow.
No extra config needed — just swap jest for jestty in your scripts and enjoy speed. ⚡

📦 Installation

npm install --save-dev jestty

or with Yarn:

yarn add --dev jestty

🚀 Usage

Run tests with the jestty binary:

npx jestty

Or add it to your package.json scripts:

{
  "scripts": {
    "test": "jestty"
  }
}

Run with options (just like Jest):

jestty --watch
jestty --coverage
jestty my-test-file.test.js

⚡ Why Jestty?

• 🚀 Optimized performance — faster test runs than plain Jest
• 🎯 Same API — works with existing Jest configs
• 🛠 Drop-in replacement — no migration headaches
• 🧩 Compatible — supports Jest CLI options

🔧 Configuration

Jestty respects your existing Jest configuration (jest.config.js, package.json > jest, etc.).
No extra setup required.
