10 Prática sobre Ferramentas de Desenvolvimento e Frameworks Ethereum: Introdução aos Testes e Deploy com `Truffle`

Introdução aos Testes e Deploy com Truffle

Resumo

Nesta aula são apresentadas algumas ferramentas de Desenvolvimento e Frameworks para o desenvolvimento e implantação de Contratos Inteligentes. Introduz o Truffle framework, que pode ser usado para testar, implantar contratos inteligentes. Vamos explorar os comandos test e migrate para executarmos testes e fazermos a implantação dos contratos. Faremos deploy para as redes simuladas do truffle, do ganache e para a Rede Privada Local, a etherprivate.

10.1 Introdução

Nesta prática são apresentadas algumas ferramentas de Desenvolvimento e Frameworks para o desenvolvimento e implantação de Contratos Inteligentes. Introduz o Truffle framework, que também pode ser usado para testar, migrar contratos inteligentes.

Apresentação de Ferramentas de Desenvolvimento e Frameworks.
Explorar o uso do Truffle para testar e implantar contratos.

10.2 Instalação das Ferramentas

Instale as outras ferramentas: Node.js, Ganache e Ganache-CLI, Truffle, Drizzle, Embark e outras ferramentas indicadas no capítulo. O truffle utiliza o nodejs nas versões v14-v18 (https://trufflesuite.com/docs/truffle/how-to/install/)
Instale o nvm para configurar a versão desejada para o Node.js e as bibliotecas necessárias.

$ sudo apt-get install nvm
$ nvm install 18

Instale o Truffle.

$ npm install -g truffle

Verifique a versão instalada das ferramentas.

10.3 Criando a estrutura básica do projeto com o `Truffle`

Iremos criar a estrutura de um projeto básico. Crie um diretório com o nome do projeto, aqui estou utilizando o nome projeto-helloworld-truffle, crie e acesse o diretório.

[src]$ mkdir projeto-helloworld-truffle
[src]$ cd projeto-helloworld-truffle/

Utilize o comando truffle init para inicializar a estrutura básica do projeto (skeleton).

[projeto-helloworld-truffle]$ truffle init

Starting init...
================

> Copying project files to .../src/projeto-helloworld-truffle

Init successful, sweet!

Try our scaffold commands to get started:
  $ truffle create contract YourContractName # scaffold a contract
  $ truffle create test YourTestName         # scaffold a test

http://trufflesuite.com/docs

[projeto-helloworld-truffle]$ ls
contracts  migrations  test  truffle-config.js
[projeto-helloworld-truffle]$
[src]$ tree projeto-helloworld-truffle/
projeto-helloworld-truffle/
|-- contracts
|-- migrations
|-- test
|-- truffle-config.js

3 directories, 1 files

Se verificarem os diretórios criados contracts, migrations e test estão vazios e foi criado um arquivo de configuração truffle-config.js.

contracts: diretório para os contratos.
migrations: diretório para os scripts de implantação (deploy).
test: diretório para os arquivos de teste.
truffle-config.js: Arquivo de configuração do Truffle.

Vamos criar um contrato com nome de Greeter para testarmos.

[projeto-helloworld-truffle]$ truffle create contract Greeter
[projeto-helloworld-truffle]$ ls contracts/
Greeter.sol

Notem que o arquivo Greeter.sol foi criado dentro do diretório contracts.

[src]$ tree projeto-helloworld-truffle/
projeto-helloworld-truffle/
|-- contracts
  |-- Greeter.sol
|-- migrations
|-- test
|-- truffle-config.js

3 directories, 2 files

Editando o contrato Greeter.sol temos uma estrutura básica já criada pelo Truffle.

// SPDX-License-Identifier: MIT
pragma solidity >=0.4.22 <0.9.0;

contract Greeter {
  constructor() public {
  }
}

Altere o código do Greeter.sol para:

// SPDX-License-Identifier: MIT
pragma solidity >=0.4.22 <0.9.0;

contract Greeter {
    string private _greeting = "Hello, World!";
    
    function greet() external view returns(string memory) {
        return _greeting;
    }
    function setGreeting(string calldata greeting) external {
        _greeting = greeting;
    }
}

Vamos criar um teste para o contrato Greeter:

[projeto-helloworld-truffle]$ truffle create test greeter_test
[projeto-helloworld-truffle]$ tree ../projeto-helloworld-truffle
../projeto-helloworld-truffle
|-- contracts
    |-- Greeter.sol
|-- migrations
|-- test
    |-- greeter_test.js
|-- truffle-config.js

4 directories, 3 files

Edite o arquivo test/greeter_test.js e altere o código para:

const GreeterContract = artifacts.require("Greeter");

/*
 * uncomment accounts to access the test accounts made available by the
 * Ethereum client
 * See docs: https://www.trufflesuite.com/docs/truffle/testing/writing-tests-in-javascript
 */
contract("Greeter", () => {
  it("has been deployed successfully", async () => {
    const greeter = await GreeterContract.deployed();
    assert(greeter, "contract was not deployed");
  });
});

Se tentarmos executar o teste para o Greeter, o teste irá falhar e emitirá uma mensagem que o contrato não existe, pois não foi feito o deploy para a rede detectada.

[projeto-helloworld-truffle]$ truffle test

Compiling your contracts...
===========================
> Compiling ./contracts/Greeter.sol
> Artifacts written to /tmp/test--524485-YnO69Mn4D3rq
> Compiled successfully using:
   - solc: 0.8.21+commit.d9974bed.Emscripten.clang


  Contract: Greeter
    1) has been deployed successfully
    > No events were emitted


  0 passing (68ms)
  1 failing

  1) Contract: Greeter
       has been deployed successfully:
     Error: Greeter has not been deployed to detected network (network/artifact mismatch)
      at Object.checkNetworkArtifactMatch (/home/rogerio/.nvm/versions/node/v18.16.0/lib/node_modules/truffle/build/ webpack:/packages/contract/lib/utils/index.js:256:1)
      at Function.deployed (/home/rogerio/.nvm/versions/node/v18.16.0/lib/node_modules/truffle/build/ webpack:/packages/contract/lib/contract/constructorMethods.js:83:1)
      at processTicksAndRejections (node:internal/process/task_queues:95:5)
      at Context.<anonymous> (test/greeter_test.js:10:21)

Toda vez que executamos o comando truffle test, o Truffle compila os contratos e então implanta eles para uma rede de teste. Para fazer o deploy precisamos de um outro arquivo migrations.

Migrations são scripts escritos em JavaScript que são usados para automatizar a implantação dos contratos.

Crie o arquivo migrations/2_deploy_greeter.js:

[projeto-helloworld-truffle]$ touch migrations/2_deploy_greeter.js

Edite o arquivo migrations/2_deploy_greeter.js e altere seu conteúdo para:

const GreeterContract = artifacts.require("Greeter");

module.exports = function(deployer) {
    deployer.deploy(GreeterContract);
}

Agora o comando de teste pode ser executado novamente:

[projeto-helloworld-truffle]$ truffle test

Compiling your contracts...
===========================
> Compiling ./contracts/Greeter.sol
> Artifacts written to /tmp/test--525087-Mn9TjRLsIpEK
> Compiled successfully using:
   - solc: 0.8.21+commit.d9974bed.Emscripten.clang


  Contract: Greeter
    [ok] has been deployed successfully


  1 passing (48ms)

Voltemos ao arquivo de teste test/greeter_test.js para adicionarmos um teste para a função greet().

describe("greet()", () => {
  it("returns 'Hello, World!'", async () => {
  const greeter = await GreeterContract.deployed();
  const expected = "Hello, World!";
  const actual = await greeter.greet();
  assert.equal(actual, expected, "greeted with 'Hello, World!'");
  });
});

Executando o teste novamente:

[projeto-helloworld-truffle]$ truffle test

Compiling your contracts...
===========================
> Compiling ./contracts/Greeter.sol
> Artifacts written to /tmp/test--525218-DtJhC1dxt2xO
> Compiled successfully using:
   - solc: 0.8.21+commit.d9974bed.Emscripten.clang


  Contract: Greeter
    [ok] has been deployed successfully

  greet()
    [ok] returns 'Hello, World!'


  2 passing (72ms)

Caso a função greet() não estivesse definida em Greeter.sol o teste falharia e uma mensagem de erro que ela não está definida seria emitida. (Comentei a função para vermos a mensagem).

[projeto-helloworld-truffle]$ truffle test

Compiling your contracts...
===========================
> Compiling ./contracts/Greeter.sol
> Artifacts written to /tmp/test--525417-6OKN7bdHq2gv
> Compiled successfully using:
   - solc: 0.8.21+commit.d9974bed.Emscripten.clang


  Contract: Greeter
    [ok] has been deployed successfully

  greet()
    1) returns 'Hello, World!'


  1 passing (36ms)
  1 failing

  1) greet()
       returns 'Hello, World!':
     TypeError: greeter.greet is not a function
      at Context.<anonymous> (test/greeter_test.js:19:32)
      at processTicksAndRejections (node:internal/process/task_queues:95:5)

A função function setGreeting(string calldata greeting) pode ser utilizada para definirmos a mensagem de saudação, deixando o comportamento dinâmico. Adicionemos ao arquivo de teste test/greeter_test.js o código para testar a função setGreeting(string...).

contract("Greeter: update greeting", () => {
  describe("setGreeting(string)", () => {
    it("sets greeting to passed in string", async () => {
      const greeter = await GreeterContract.deployed()
      const expected = "Hi there!";
      await greeter.setGreeting(expected);
      const actual = await greeter.greet();
    
      assert.equal(actual, expected, "greeting was not updated");
    });
  });
});

Executando o teste novamente:

[projeto-helloworld-truffle]$ truffle test

Compiling your contracts...
===========================

  Contract: Greeter
    [ok] has been deployed successfully

  greet()
    [ok] returns 'Hello, World!'

  Contract: Greeter: update greeting
    setGreeting(string)
      [ok] sets greeting to passed in string (75ms)


  3 passing (153ms)

Até aqui temos um projeto básico com teste.

10.4 Definindo um dono para o Contrato

Adicionemos ao arquivo de teste do contrato o teste para uma função que retorna o proprietário do contrato.

contract("owner()", (accounts) => {
    it("returns the address of the owner", async () => {
        const greeter = await GreeterContract.deployed();
        const owner = await greeter.owner();
        assert(owner, "the current owner");
    });
  });

Executando os testes novamente irá dar erro pois a função owner() não foi definida.

[projeto-helloworld-truffle]$ truffle test

Compiling your contracts...
===========================
> Compiling ./contracts/Greeter.sol
> Artifacts written to /tmp/test--526818-prsf62z8pH8F
> Compiled successfully using:
   - solc: 0.8.21+commit.d9974bed.Emscripten.clang


  Contract: Greeter
    [ok] has been deployed successfully
    greet()
      [ok] returns 'Hello, World!'
    Contract: Greeter: update greeting
      setGreeting(string)
        [ok] sets greeting to passed in string (82ms)
    owner()
      1) returns the address of the owner
    > No events were emitted


  3 passing (190ms)
  1 failing

  1) Contract: Greeter
       owner()
         returns the address of the owner:
     TypeError: greeter.owner is not a function
      at Context.<anonymous> (test/greeter_test.js:41:35)
      at processTicksAndRejections (node:internal/process/task_queues:95:5)

Adicionemos um atributo _owner e a função no Greeter.sol.

// SPDX-License-Identifier: MIT
pragma solidity >=0.4.22 <0.9.0;

contract Greeter {
    string private _greeting = "Hello, World!";
    address private _owner;
    
    function greet() external view returns(string memory) {
        return _greeting;
    }
    
    function setGreeting(string calldata greeting) external {
        _greeting = greeting;
    }

    function owner() public view returns(address) {
        return _owner;
    }
}

Executando o teste novamente.

[projeto-helloworld-truffle]$ truffle test

Compiling your contracts...
===========================
> Compiling ./contracts/Greeter.sol
> Artifacts written to /tmp/test--527178-w5UnYmv6jPUK
> Compiled successfully using:
   - solc: 0.8.21+commit.d9974bed.Emscripten.clang


  Contract: Greeter
    [ok] has been deployed successfully
    greet()
      [ok] returns 'Hello, World!'
    Contract: Greeter: update greeting
      setGreeting(string)
        [ok] sets greeting to passed in string (84ms)
    owner()
      [ok] returns the address of the owner


  4 passing (200ms)

O que realmente queremos testar é se o endereço em owner é o mesmo endereço que de quem fez o deploy. Adicionemos para isso uma verificação se o endereço de propriedade é o mesmo da conta padrão que fez a implantação do contrato. Para testarmos isso, precisamos recuperar a variável accounts do ambiente de teste do Truffle.

Altere o arquivo de teste para fazer a verificação:

contract("owner()", (accounts) => {
    it("returns the address of the owner", async () => {
        const greeter = await GreeterContract.deployed();
        const owner = await greeter.owner();
        assert(owner, "the current owner");
    });
    
    it("matches the address that originally deployed the contract", async () => {
        const greeter = await GreeterContract.deployed();
        const owner = await greeter.owner();
        const expected = accounts[0];
        assert.equal(owner, expected, "matches address used to deploy contract");
    });
    
  });

A conta também pode ser verificada com o console do Truffle:

[projeto-helloworld-truffle]$ truffle console
truffle(ganache)> accounts
[
  '0x5C93A5B7BDB9bDc43322F774Cb968e3b01Ab3279',
  '0xd6724701fF337dD6512dD7FaD102F58fCA66570f',
  '0x96E3D79D3D7520096302058d28D148D115F7Beba',
  '0x6d68B588E706d70625A9B233F0e750c75dCc5B17',
  '0xD2E25790e56eE9C1E7E2DeD6d52b8fad745F3de6',
  '0x1ED231Ce2f5217C3Ea1714ce93364edC162FB028',
  '0x8F0F639B591219A6221E64D5810E82b6ce22Df23',

  '0x344b14B22d9EDf6cCdCadf00Fe9Aa78730a66A49'
]
truffle(ganache)>

Adicione o construtor ao contrato Greeter.sol

// SPDX-License-Identifier: MIT
pragma solidity >=0.4.22 <0.9.0;

contract Greeter {
    string private _greeting = "Hello, World!";
    address private _owner;

    constructor() public {
        _owner = msg.sender;
    }
    
    function greet() external view returns(string memory) {
        return _greeting;
    }
    
    function setGreeting(string calldata greeting) external {
        _greeting = greeting;
    }

    function owner() public view returns(address) {
        return _owner;
    }
}

Executando o teste novamente.

10.5 Utilizando o `OpenZeppelin`

Uma outra forma de fazer essa implementação de verificação de propriedade pode ser feita com a biblioteca OpenZeppelin que além de já ter algumas implementações que ajudam na criação de contratos que podem ser usadas na criação de tokens, ele também tem contratos que implementam a ideia de propriedade (ownership), e no que implementamos duplicamos esse comportamento. Vamos atualizar o Greeter.sol para utilizar o que já tem pronto na OpenZeppelin.

Instale o pacote openzeppelin-solidity.

[projeto-helloworld-truffle]$ npm install openzeppelin-solidity

added 1 package in 4s

Altere o código do Greeter.sol para:

pragma solidity >=0.4.22 <0.9.0;
import "openzeppelin-solidity/contracts/ownership/Ownable.sol";
contract Greeter is Ownable {
...rest of file...

O código do Greeter.sol ficando como segue:

// SPDX-License-Identifier: MIT
pragma solidity >=0.4.22 <0.9.0;

import "openzeppelin-solidity/contracts/access/Ownable.sol";

contract Greeter is Ownable {
  string private _greeting = "Hello, World!";

  function greet() external view returns(string memory) {
    return _greeting;
  }

  function setGreeting(string calldata greeting) external onlyOwner {
    _greeting = greeting;
  }
}

Reexecutando os testes:

[projeto-helloworld-truffle]$ truffle test

10.6 Deploy de Contratos com `Truffle`

10.7 Deploy de Contratos na rede simulada do `Truffle`

O comando truffle develop instancia uma rede develop do próprio truffle para que possamos executar os mesmos comandos que foram executados na prática anterior: compile, test e migrate. Ao executar o truffle com develop ele cria a rede com contas e uma chave privada que pode ser adicionada inclusive em carteiras como o Metamask para o desenvolvimento. Também disponibiliza um console javascript no qual podemos executar os comandos compile, test e migrate e interagir com o contrato implantado.

10.8 Deploy de Contratos em outras Redes

Nesta prática iremos utilizar o truffle para fazermos o deploy (implantação) de contratos para as redes de teste que utilizamos até o momento.

Estamos utilizando as redes simuladas do ganache, a ganache ou ganache-cli no console e a ganache-ui (AppImage), e a Rede Privada Local, a etherprivate.

A etherprivate está executando o servidor RPC no endereço http://127.0.0.1:8559 com o id \(786\), a rede do ganache via console com os comandos ganache ou ganache-cli no http://127.0.0.1:8545 com id \(2525\) e a ganache-ui está executando no endereço http://127.0.0.1:7545 com id \(5777\).

As configurações das redes podem ser passadas para o arquivo truffle-config.js:

 networks: {
    // Useful for testing. The `development` name is special - truffle uses it by default
    // if it's defined here and no other network is specified at the command line.
    // You should run a client (like ganache, geth, or parity) in a separate terminal
    // tab if you use this network and you must also set the `host`, `port` and `network_id`
    // options below to some value.
    //
    // development: {
    //  host: "127.0.0.1",     // Localhost (default: none)
    //  port: 8545,            // Standard Ethereum port (default: none)
    //  network_id: "*",       // Any network (default: none)
    // },
        // Ganache AppImage (ganache-ui).
    ganacheui: { 
      host: "127.0.0.1",     // Localhost (default: none)
      port: 7545,            // Standard Ethereum port (default: none)
      network_id: "5777",       // Any network (default: none)
    },
    // RAGEtherPrivate.
    etherprivate: {
      host: "127.0.0.1",     // Localhost (default: none)
      port: 8559,            // Standard Ethereum port (default: none)
      network_id: "786",       // Any network (default: none)
    },
    // ganache ou ganache-cli (console)
    ganachecli: {
      host: "127.0.0.1",
      port: 8545,
      network_id: "2525",
    },    
  }

10.9 Deploy na Rede do `Ganache-UI`

Para executarmos o teste semelhante ao que fizemos com o truffle utilizando uma instância própria do ganache, a execução padrão, vamos executar o teste utilizando uma das redes.

Para listarmos as redes disponíveis podemos executar o comando truffle networks:

[projeto-helloworld-truffle]$ truffle networks

Network: etherprivate (id: 786)
  No contracts deployed.

Network: ganachecli (id: 2525)
  No contracts deployed.

Network: ganacheui (id: 5777)
  No contracts deployed.

Vamos iniciar os testes com a rede criada pelo ganache-ui:

[projeto-helloworld-truffle]$ truffle test --network ganacheui
Using network 'ganacheui'.

WARN [10-05|21:31:02.588] Served eth_estimateGas                   conn=127.0.0.1:39264 reqid=12 duration=1.742993ms  err="invalid opcode: PUSH0"

O que explica a mensagem recebida de opcode inválido. Está ocorrendo algum problema de versão entre compilador e conjunto de instruções suportado pela EVM da versão do cliente geth.

Procurando pelo erro “invalid opcode: PUSH0” encontramos uma possível solução no link.

With Solc version 0.8.20, the default EVM version is set to “Shanghai”. A new opcode, PUSHO, was added to the Ethereum Virtual Machine in the Shanghai upgrade. That means the PUSH0 opcode can now be part of the contract’s bytecode. If your private chain does not support it, it will error with the “Invalid opcode” error.

The solution is to manually set the EVM version to some previous version, for example, “Paris” (the version before, also known as The Merge), instead of “Shanghai”, which is the default now.

Dando a solução do que fazer em cada uma das ferramentas. A problema é o que suspeitávamos, erro de versões do código gerado pelo solc e o conjunto de instruções aceito pela EVM.

Como no material cita que a instrução PUSH0 foi adicionada na versão Shanghai da EVM, vamos voltar ao Ganache e configura o hardfork para esta versão.

A versão do Ganache que estávamos rodando é a v2.71 via AppImage

Vamos baixar o código da última release Versão 7.9.0

Instalando diretamente com npm install ganache --global a versão instalada é a \(7.9.1\), mas só tem o ganache e o ganache-cli. O ganache-ui está na versão \(2.7.1\).

A versão ganache e ganache-cli possibilitam vermos os resultados no console, mas vamos tentar gerar um App.image da versão atual.

#!/bin/bash

# Clone Ganache repository
git clone https://github.com/trufflesuite/ganache.git
cd ganache

# Install dependencies and build Ganache
npm install
npm run build

# Download appimagetool

No Manjaro não funcionou.

10.13 Alterando a versão da EVM alvo

Uma possibilidade é modificarmos as configurações para gerar para uma das redes suportadas no ganache-ui. A configuração que deixamos foi com hardfork Merge. Vamos alterar na guia chain para a London e alterar o compilador para gerar código para essa versão.

Alteramos no arquivo truffle-config.js as configurações do solc:

// Configure your compilers
  compilers: {
    solc: {
      version: "0.8.21",      // Fetch exact version from sol>
      // evmVersion: "shanghai"
      evmVersion: "london"
    }
  },
