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

Quickstart

yarn add @depay/web3-mock --dev

or

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

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

Basics

EVM: Basics

1import { mock } from '@depay/web3-mock'
2
3describe('something', ()=> {
4
5  beforeEach(()=>mock('ethereum'))
6
7  it('does something', ()=>{
8
9    await window.ethereum.request(method: 'eth_chainId') // '0x1'
10    await window.ethereum.request(method: 'net_version') // 1
11
12  })
13})

Solana: Basics

Requires explicit provider mocking (see Providers)

1
2let connection = new Connection('https://api.mainnet-beta.solana.com')
3mock({ blockchain: 'solana', provider: connection })
4
5let block = connection.getBlockHeight()
6block // 1
7
8let blockHash = connection.getLatestBlockhash()
9blockHash // { blockhash: "6ErPTEaPmVUwEPeX4MAiCEEC7fJ254zCdq6M294JozDx", lastValidBlockHeight: 123 }

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:

1import { WagmiConfig, createConfig, mainnet } from 'wagmi'
2import { createPublicClient, custom } from 'viem'
3
4const config = createConfig({
5  autoConnect: true,
6  publicClient: createPublicClient({
7    chain: mainnet,
8    transport: custom(window.ethereum),
9  }),
10})
11
12//...
13
14mock({
15  blockchain: 'ethereum',
16  balance: {
17    for: '0xb0252f13850a4823706607524de0b146820F2240',
18    return: '232111122321'
19  }
20})

Support

This library supports the following blockchains:

• Ethereum
• BNB Smart Chain
• Polygon
• Solana
• Fantom
• Arbitrum
• Avalanche
• Gnosis
• Optimism
• Base

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

• MetaMask
• Coinbase Wallet
• Phantom

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

1import { mock } from '@depay/web3-mock-evm'

Solana platform specific package

1import { mock } from '@depay/web3-mock-solana'

Functionalities

Basic Implicit Mocks

EVM: Basic Implicit Mocks

1mock('ethereum')
2
3await window.ethereum.request({ method: 'eth_chainId' }) // '0x1'
4await window.ethereum.request({ method: 'net_version' }) // 1
5await window.ethereum.request({ method: 'eth_getBalance' }) // '0x0'
6await window.ethereum.request({ method: 'eth_estimateGas' }) // '0x2c4a0'
7await window.ethereum.request({ method: 'eth_blockNumber' }) // '0x5daf3b'
8await window.ethereum.request({ method: 'eth_subscribe' }) // undefined

Solana: Basic Implicit Mocks

1// requires explicit provider mocking (see #Providers)
2
3let connection = new Connection('https://api.mainnet-beta.solana.com')
4mock({ blockchain: 'solana', provider: connection })
5
6let block = connection.getBlockHeight()
7block // 1

Accounts

Mocks accounts and wallet connect processes:

1mock({
2  blockchain,
3  accounts: {
4    return: ['0xd8da6bf26964af9d7eed9e03e53415d37aa96045']
5  }
6})

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

1mock({
2  blockchain,
3  accounts: {
4    delay: 10000, // ms
5    return: ['0xd8da6bf26964af9d7eed9e03e53415d37aa96045']
6  }
7})
8// 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:

1mock({
2  blockchain,
3  accounts: {
4    return: Error('User rejected the request.')
5  }
6})

Request Data

You need to mock requests before they are executed.
