abi-to-mock-demo v1.0.0

ABI-to-Mock

Generate Solidity mock contracts automatically from Ethereum ABIs.

Features

• Generates fully functional Solidity mock contracts
• Supports complex data types including structs and nested arrays
• Handles both functions and events
• Maintains function signatures and event definitions
• Customizable contract names and output locations
• Available as both CLI tool and JavaScript library

Quick Start

Generate a mock contract from an example ABI:

node src/cli.js tests/fixtures/StabilityPool.json --name StabilityPool

This will generate a mock implementation of the StabilityPool contract in the default ./out directory.

Installation

npm install abi-to-mock

Usage

Command Line Interface

npx abi-to-mock <abi-file> [options]

Options:

• --out, -o: Output directory (default: "./out")
• --name, -n: Contract name (default: "Contract")

Example:

npx abi-to-mock ./MyContract.json --out ./mocks --name MyContract

Programmatic Usage

const AbiToMock = require('abi-to-mock');

// Generate mock from ABI file
AbiToMock('./MyContract.json', './mocks', 'MyContract');

// Or use ABI object directly
const abi = [/* your ABI array */];
AbiToMock.generateMock(abi, './mocks', 'MyContract');

Generated Mock Features

• Maintains original function signatures
• Implements customizable return values
• Tracks function calls and parameters
• Supports event emission
• Handles complex data structures
• Memory-safe implementation

Parameters:

• abiPath (string): Path to ABI JSON file
