Solidity test using truffle + ganache

Solidity Programming Practice

Truffle console example :

$truffle console

truffle(ganache)> let instance = await METoken.deployed() undefined

truffle(ganache)> let accounts = await web3.eth.getAccounts()

undefined

truffle(ganache)> accounts

[ '0x6B942ed5a758B16458329DbB7873F04A9942Fbe8', ... ]

truffle(ganache)> instance.approve(accounts[0], 10000)

truffle(ganache)> instance.balanceOf(accounts[0])

BN { negative: 0, words: [ 1000000, <1 empty item> ], length: 1, red: null }

truffle(ganache)> instance.transferFrom(accounts[0], METFaucet.address, 1000)

truffle(ganache)> instance.balanceOf(METFaucet.address)

BN { negative: 0, words: [ 1000, <1 empty item> ], length: 1, red: null }

truffle(ganache)> instance.approve(accounts[1], 1000)

truffle(ganache)> METFaucet.deployed().then(instance => {instance.withdraw(100, {from:accounts[1]})})

undefined

truffle(ganache)> instance.balanceOf(accounts[1]) BN { negative: 0, words: [ 100, <1 empty item> ], length: 1, red: null }

truffle(ganache)> instance.balanceOf(METFaucet.address)

BN { negative: 0, words: [ 1000, <1 empty item> ], length: 1, red: null }

truffle(ganache)>
