scriptable-testlab

A comprehensive testing framework for simulating the Scriptable iOS app runtime environment

Introduction

scriptable-testlab is a testing framework specifically designed for the Scriptable iOS app. It provides a complete mock runtime environment that enables developers to write and run unit tests without depending on physical iOS devices. The framework strictly implements types defined in @types/scriptable-ios to ensure type safety and precise API simulation.

Core Features

• 🔄 Complete Scriptable API simulation with strict type safety
• 🧪 Comprehensive mock implementations for all Scriptable modules
• 📱 Device-independent testing environment with runtime simulation
• 🔍 Type-safe development experience with full TypeScript support
• ⚡ Fast and lightweight runtime based on scriptable-abstract
• 🛠️ Seamless Jest integration with full testing utilities
• 📊 Built-in test coverage support and mock assertions
• 🔌 Modular architecture with pluggable components
