This is the second test for the Solana Rust program

test.js

import { expect } from 'chai' // Keep this at the beginning of the file along with the other imports

it('Should write an article with 1 word successfully', async () => {
  const deployerKeypair = anchor.web3.Keypair.generate()
  const personThatPays = program.provider.wallet

  // Add your test here
  await program.rpc.initialize({
    accounts: {
      article: deployerKeypair.publicKey,
      personThatPays: personThatPays.publicKey,
      systemProgram: anchor.web3.SystemProgram.programId,
    },
    signers: [deployerKeypair],
  })
  
  await program.rpc.writeIntoArticle('hey', {
    accounts: {
      article: deployerKeypair.publicKey,
    },
    signers: [],
  })

  const articleData = await program.account.article.fetch(deployerKeypair.publicKey)
  expect(articleData.content).to.equal('hey ') // Note the space at the end, added by the program
})
