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.

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, such as:
Platform specific packaging
In case you want to use and package only specific platforms, use platform specific packages:
import { mock } from '@depay/web3-mock-evm'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' }) // undefinedSolana: 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 // 1Accounts
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.

In order to delay the response of a transaction in your tests (to emulate real life behaviour), you can use delay:
let requestMock = mock({
blockchain: 'ethereum',
transaction: {
delay: 1000,
from: '0xd8da6bf26964af9d7eed9e03e53415d37aa96045',

amounts: anything
}
}
})
// this is gonna take at least 1000ms
let transaction = await contract.connect(signer).route(

)Estimates
Explicit estimate mocks are not required, they are implicitly mocked with a default value once web3-mock is initalized.
In case you want to explicitly want to test that your code performs an estimate and does not perform the transaction, use estimate mocks:
import { mock } from '@depay/web3-mock'
let mockedEstimate = mock({
blockchain: 'ethereum',
estimate: {
api: ERC20,
from: '0xd8da6bf26964af9d7eed9e03e53415d37aa96045',
to: '0xa0bEd124a09ac2Bd941b10349d8d224fe3c955eb',
method: 'transfer',
return: '200' // the gas you want to be returned to your code
}
})
let provider = new ethers.providers.Web3Provider(global.ethereum)
let signer = provider.getSigner()
let contract = new ethers.Contract(
'0xa0bEd124a09ac2Bd941b10349d8d224fe3c955eb',
ERC20,
provider
)
let estimate = await contract.connect(signer).estimateGas.transfer('0xd8da6bf26964af9d7eed9e03e53415d37aa96045', '100')
expect(estimate.toString()).toEqual('200')
expect(mockedEstimate).toHaveBeenCalled()In case you want to require all estimate requests being mocked you need to enable that explicitly (unlike calls or transactions which are always required):
import { mock } from '@depay/web3-mock'
mock({ blockchain: 'ethereum', require: 'estimate' })Signature
web3-mock allows you to mock signatures:
let message = "This is a message to be signed\n\nAnd a new line"
const messageUtf8 = ethers.utils.toUtf8Bytes(message)
const messageHex = ethers.utils.hexlify(messageUtf8).substring(2)
mock({
blockchain: 'ethereum',
signature: {
params: [accounts[0], `0x${messageHex}`],
return: "0x123456"
}
})
await signer.signMessage(message)
// RawSignature
// "0x123456"including signed data:
let data = {
domain: {
...
},
message: {
...
},
primaryType: 'Person',
types: {
...
},
}
const messageHex = sigUtil.signTypedData_v4(secret, { data })
mock({
blockchain: 'ethereum',
accounts :{ return :accounts},
signature: {
params: [accounts[0], JSON.stringify(data)],
return: "0x123456"
}
})
//code under test
await window.ethereum.request({
method: 'eth_signTypedData_v4',
params: [accounts[0], JSON.stringify(data)],
from: accounts[0]
})
// RawSignature
// "0x123456"Also allows to delay signature:
mock({
blockchain: 'ethereum',
signature: {
params: [accounts[0], `0x${messageHex}`],
return: "0x123456",
delay: 5000
}
})Balance
web3-mock allows you to mock balance requests:
EVM: Balance
let balanceMock = mock({
blockchain: 'ethereum',
balance: {
for: '0xb0252f13850a4823706607524de0b146820F2240',

let provider = new ethers.providers.Web3Provider(global.ethereum);
let balance = await provider.getBalance('0xb0252f13850a4823706607524de0b146820F2240')
// BigNumber<'232111122321'>let balanceMock = mock({
blockchain: 'ethereum',
balance: {

let provider = new ethers.providers.Web3Provider(global.ethereum);
let signer = provider.getSigner();
let balance = await signer.getBalance()
// BigNumber<'123'>Solana: Balance
let connection = new Connection('https://api.mainnet-beta.solana.com')
let balanceMock = mock({

web3-mock allows you to mock interacting with a wallets network setting (like switching or adding networks).
EVM: Switch Network
let switchMock = mock({
blockchain: 'ethereum',
network: {
switchTo: 'bsc'
}
})
let blockchain = Blockchain.findByName('bsc')
await global.ethereum.request({ method: 'wallet_switchEthereumChain', params: [{ chainId: blockchain.id }] })let switchMock = mock({
blockchain: 'ethereum',
network: {
switchTo: 'bsc',
error: ()=> {
return { code: 4902 }
}
}
})
let blockchain = Blockchain.findByName('bsc')
await global.ethereum.request({ method: 'wallet_switchEthereumChain', params: [{ chainId: blockchain.id }] })
// throws { code: 4902 }let blockchain = Blockchain.findByName('bsc')
let addMock = mock({
blockchain: 'ethereum',
network: {
add: {
chainId: blockchain.id,
chainName: blockchain.fullName,
nativeCurrency: {
name: blockchain.currency.name,
symbol: blockchain.currency.symbol,
decimals: blockchain.currency.decimals
},
rpcUrls: [blockchain.rpc],
blockExplorerUrls: [blockchain.explorer],
iconUrls: [blockchain.logo]
}
}
})
await global.ethereum.request({
method: 'wallet_addEthereumChain',
params: [{
chainId: blockchain.id,
chainName: blockchain.fullName,
nativeCurrency: {
name: blockchain.currency.name,
symbol: blockchain.currency.symbol,
decimals: blockchain.currency.decimals
},
rpcUrls: [blockchain.rpc],
blockExplorerUrls: [blockchain.explorer],
iconUrls: [blockchain.logo]
}]
})Connect wallet to another blockchain
import { connect } from '@depay/web3-mock'
connect('ethereum')
// ...
connect('bsc')Errors
For all mocking types (request, transaction, estimate & balance) you can also test error cases by setting return to an Error:
mock({
blockchain: 'ethereum',
request: {
//...
return: Error('Some error happened')
}
})
Events
web3-mock allows you to trigger events (like accountsChanged).
import { mock, trigger } from '@depay/web3-mock'
mock('ethereum')
// some other prep and test code
trigger('accountsChanged', ['0xb0252f13850a4823706607524de0b146820F2240', '0xEcA533Ef096f191A35DE76aa4580FA3A722724bE'])also allows you to trigger walletConnect events, too:
import { mock, trigger } from '@depay/web3-mock'
import { wallets } from '@depay/web3-wallets'
mock({ blockchain: 'ethereum', wallet: 'walletconnect', connector: wallets.WalletConnect })
trigger('connected', [error, payload])In order to achieve event mocking, web3-mock mocks internal event handling via .on, .removeListener and .off.
Providers
If you want to mock Web3 requests and transactions for a specific provider, pass the provider you want to instrument:
EVM: Providers
let provider = new ethers.providers.JsonRpcProvider('https://example.com');
mock({
provider,
blockchain: 'ethereum'
// ...
})Solana: Providers
let connection = new Connection('https://api.mainnet-beta.solana.com')
mock({
provider: connection,
blockchain: 'solana',
balance: {
for: '5AcFMJZkXo14r3Hj99iYd1HScPiM4hAcLZf552DfZkxa',
return: 232111122321
}
})
let balance = await connection.getBalance(new PublicKey('5AcFMJZkXo14r3Hj99iYd1HScPiM4hAcLZf552DfZkxa'))
expect(balance).toEqual(232111122321)Wallets
Crypto wallets identify themselfs differently, in order to mock those wallet identifications, you can also use mock:
mock({
blockchain: 'ethereum',
wallet: 'metamask'
})
window.ethereum.isMetaMask // trueMetaMask
mock({
blockchain: 'ethereum',
wallet: 'metamask'
})
window.ethereum.isMetaMask // trueCoinbase
mock({
blockchain: 'ethereum',
wallet: 'coinbase'
})
window.ethereum.isCoinbaseWallet // true
window.ethereum.isWalletLink // trueWalletConnect
import { wallets } from '@depay/web3-wallets'
mock({
blockchain: 'ethereum',
wallet: 'walletconnect',
connector: wallets.WalletConnect
})
// simulates walletconnect connect flow
// and allows to trigger walletconnect events with "trigger"Coinbase WalletLink
import { wallets } from '@depay/web3-wallets'
mock({
blockchain: 'ethereum',
wallet: 'walletlink',
connector: wallets.WalletLink
})
// simulates coinbase walletlink connect flow
// and allows to trigger walletlink events with "trigger"Test Helpers
normalize
normalize allows you to normalize values to compare them easier in tests:
import { normalize } from '@depay/web3-mock'
expect(
normalize('0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D')
).toEqual('0x7a250d5630b4cf539739df2c5dacb4c659f2488d')
expect(
normalize(ethers.BigNumber.from('1000'))
).toEqual('1000')window
Pass a window object in case it is not supposed to be the implicit window.
mock({
window: anotherObject,
blockchain: 'ethereum'
// ...
})Development

Testing
Jest
In your jest test environment global is the window available to your code.
Hence web3-mock instrumentalizes Jest's global automatically when using web3-mock in a jest test environment.
Make sure you add the following to your jest setup (tests/setup.js).
// web3-mock polyfills:
global.XMLHttpRequest = require('xhr2')
global.location = { host: undefined }Install xhr2 as a dev dependency if it is not already installed.
Cypress
In your cypress test environment cy.window().specWindow.window is the window available to your code.
Hence web3-mock takes cypress's cy.window().specWindow.window automatically when using web3-mock in a cypress test environment.
web3-mock supports Cypress's Sinon-Chai matchers for called, calledOnce and callCount(n):
let transactionMock = mock({ ... })
expect(transactionMock).to.have.been.called
expect(transactionMock).to.have.been.calledOnce
expect(transactionMock).to.have.been.callCount(n)Playwright
Playwright requires the following setup in your playwright config file:
// web3-mock polyfills:
global.XMLHttpRequest = require('xhr2')
global.location = { host: undefined }
