@jet-lab/e2e-react-adapter

What is it?

@jetlab/e2e-react-adapter is a test adapter for solana decentralised applications. It allows to interact with your application without having to go through a browser extension, this in turn enables end-to-end testing. It also allows to programmatically reject transaction, so you can test the sad paths too.

Why?

We have found difficult to integrate a solid end-to-end test suite by using what's currently available in the ecosystem. As we care about bug free code, it was a no-brainer to create an adapter that enabled e2e testing.

Installation

To install: yarn add @jet-lab/e2e-react-adapter or npm -i @jet-lab/e2e-react-adapter

Usage

Simply add your wallet adapter to the array of adapters you normally send to your wallet-adapter-react

import  {  WalletProvider  }  from  '@solana/wallet-adapter-react';
import {
  PhantomWalletAdapter,
  MathWalletAdapter,
  SolflareWalletAdapter,
  SolongWalletAdapter,
  SolletWalletAdapter
} from '@solana/wallet-adapter-wallets';
import { E2EWalletAdapter } from 'e2e-react-adapter';
import { useMemo } from 'react';
import Main from './Main'

export  function  App(): JSX.Element  {
  const wallets = useMemo(() => [
    new PhantomWalletAdapter(),
    new MathWalletAdapter(),
    new SolflareWalletAdapter(),
    new SolongWalletAdapter(),
    new SolletWalletAdapter(),
    new SlopeWalletAdapter(),
    new E2EWalletAdapter()
  ]}, []);
  return <WalletProvider  wallets={wallets}  autoConnect>
	  <Main />
  </WalletProvier>
}

The library will generate a new kepair each time is re-run so you either need to have an airdrop functionality on your localnet / devnet instance or you can pass a keypair object to the constructor like so:

new E2EWalletAdapter({
  keypair: <your_keypair>
})

optionally you can also programmatically reject to send or signing a transaction with adapter.rejectNext() or window.solanaE2E.rejectNext()
