web3 mock testing blockchain wallets crypto

Simplify testing your dApps by mocking blockchain providers and wallets with web3-mock.

Quickstart

yarn add @depay/web3-mock --dev

npm install --save-dev @depay/web3-mock

Make sure you setup Jest, Cypress or Playwright correctly before start using web3-mock.

Basics

EVM: Basics

import { mock } from '@depay/web3-mock'

describe('something', ()=> {

  beforeEach(()=>mock('ethereum'))

  it('does something', ()=>{

    await window.ethereum.request(method: 'eth_chainId') // '0x1'
    await window.ethereum.request(method: 'net_version') // 1

  })
})

Solana: Basics

Requires explicit provider mocking (see Providers)


let connection = new Connection('https://api.mainnet-beta.solana.com')
mock({ blockchain: 'solana', provider: connection })

let block = connection.getBlockHeight()
block // 1

let blockHash = connection.getLatestBlockhash()
blockHash // { blockhash: "6ErPTEaPmVUwEPeX4MAiCEEC7fJ254zCdq6M294JozDx", lastValidBlockHeight: 123 }

Providers

viem / wagmi

viem makes it's own internal public client inaccesible for external mocks due to their decorator pattern (see: https://github.com/wagmi-dev/viem/blob/main/src/clients/createPublicClient.ts#LL86C8-L86C21).

That's why only the custom(window.ethereum) is compatible with web3-mock:

import { WagmiConfig, createConfig, mainnet } from 'wagmi'
import { createPublicClient, custom } from 'viem'

const config = createConfig({
  autoConnect: true,
  publicClient: createPublicClient({
    chain: mainnet,
    transport: custom(window.ethereum),
  }),
})

//...

mock({
  blockchain: 'ethereum',
  balance: {
    for: '0xb0252f13850a4823706607524de0b146820F2240',
    return: '232111122321'
  }
})

Support

This library supports the following blockchains:

This library supports the all crypto wallets that inject window.ethereum or window.solana like:

100+ different wallets via WalletConnect.

Platform specific packaging

In case you want to use and package only specific platforms, use platform specific packages:

EVM platform specific package

import { mock } from '@depay/web3-mock-evm'

Solana platform specific package

import { mock } from '@depay/web3-mock-solana'

Functionalities

Basic Implicit Mocks

EVM: Basic Implicit Mocks

mock('ethereum')

await window.ethereum.request({ method: 'eth_chainId' }) // '0x1'
await window.ethereum.request({ method: 'net_version' }) // 1
await window.ethereum.request({ method: 'eth_getBalance' }) // '0x0'
await window.ethereum.request({ method: 'eth_estimateGas' }) // '0x2c4a0'
await window.ethereum.request({ method: 'eth_blockNumber' }) // '0x5daf3b'
await window.ethereum.request({ method: 'eth_subscribe' }) // undefined

Solana: Basic Implicit Mocks

// requires explicit provider mocking (see #Providers)

let connection = new Connection('https://api.mainnet-beta.solana.com')
mock({ blockchain: 'solana', provider: connection })

let block = connection.getBlockHeight()
block // 1

Accounts

Mocks accounts and wallet connect processes:

mock({
  blockchain,
  accounts: {
    return: ['0xd8da6bf26964af9d7eed9e03e53415d37aa96045']
  }
})

Also allows you to test a "connect wallet screen" by delaying the mock:

mock({
  blockchain,
  accounts: {
    delay: 10000, // ms
    return: ['0xd8da6bf26964af9d7eed9e03e53415d37aa96045']
  }
})
// will wait 10s before returning with the address (emulating user granting access to the wallet)

Also allows you to test a "connection failed" by returning an error:

mock({
  blockchain,
  accounts: {
    return: Error('User rejected the request.')
  }
})

Request Data

You need to mock requests before they are executed.
