Question

I learn the demo: Code is come from: https://truffleframework.com/tutorials/pet-shop, when I test:
$ truffle.cmd test
Using network 'development'.
Compiling .\test\TestAdoption.sol...

I updated my nodejs lastest, and installed window-build-tools,it does not work.
TestAdoption.sol:
pragma solidity ^0.5.0;
import "truffle/Assert.sol";
import "truffle/DeployedAddresses.sol";
import "../contracts/Adoption.sol";
contract TestAdoption {
Adoption adoption = Adoption(DeployedAddresses.Adoption());
function testUserCanAdoptPet() public {
uint returnedId = adoption.adopt(expectedPetId);
Assert.equal(returnedId, expectedPetId);
}
uint expectedPetId = 8;
address expectedAdopter = address(this);
function testGetAdopterAddressByPetId() public {
address adopter = adoption.adopters(expectedPetId);
Assert.equal(adopter, expectedAdopter, "Owner of the expected pet should be this contract");
}
function testGetAdopterAddressByPetIdInArray() public {
address[16] memory adopters = adoption.getAdopters();
Assert.equal(adopters[expectedPetId], expectedAdopter, "Owner of the expected pet should be this contract");
}
}
2_deploy_contracts.sol:
var Adoption = artifacts.require("Adoption");
module.exports = function(deployer) {
deployer.deploy(Adoption);
};
And import "truffle/Assert.sol"; vscode say: Source "truffle/Assert.sol" not found: File import callback not supported.My friend's version is 0.4.14 and work well, may be a version problem?
Here is project dir(just a demo from https://truffleframework.com/tutorials/pet-shop):

Answer 1

This error DOESN'T happen (currently) in the version v5.1.10 of truffle.
My full error was:
TypeError: Error parsing C:/Users/PATH/yourSmartContract.sol: Cannot destructure property 'body' of 'undefined' as it is undefined.
My solution is to downgrade the version like so:
$ npm uninstall -g truffle
$ npm install -g truffle#v5.1.10
(Developing in BC is hard because of version control and managment. Keep the good the work.)

Answer 2

The problem is the name of the artifact is defined according to the contract's name. This is your contract:
contract TestAdoption {
}
So;
2_deploy_contracts.sol:
// not artifactsrequire(Adoption)
var Adoption = artifacts.require("TestAdoption");
module.exports = function(deployer) {
deployer.deploy(Adoption);
};

Answer 3

Try these files:
1_initial_migration.js:
const Migrations = artifacts.require("Migrations");
module.exports = function(deployer) {
deployer.deploy(Migrations);
};
2_deploy_contracts.js:
const YourContractName = artifacts.require("YourContractName");
module.exports = function(deployer) {
deployer.deploy(YourContractName);
};
Tips:
Do not change the name of the files (1_initial_migration.js and 2_deploy_contracts.js);
Use the exactly name of your contract in the "2_deploy_contracts" file (if it is called BatatinhaFrita123, you need to specify BatatinhaFrita123 inside the artifacts.require()).
