@depay/web3-mock

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.

#### EVM: Basics

`javascript
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

})
})
`

#### SVM: Basics

Requires explicit provider mocking (see Providers)

`javascript

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 }

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:

`javascript
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:

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

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:

$3

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

$3

`javascript
import { mock } from '@depay/web3-mock-svm'
`

Functionalities

$3

#### EVM: Basic Implicit Mocks

`javascript
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
`

#### SVM: Basic Implicit Mocks

`javascript
// 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
`

$3

Mocks accounts and wallet connect processes:

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

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

`javascript
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:

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

$3

You need to mock requests before they are executed.
