But nothing works!!!
Here's the test file election.js
var Election = artifacts.require('./Election.sol');
contract("Election",function(accounts){
it("Initializes with two candidates",function(){ //Mocha framework
return Election.deployed().then(function(instance){
return instance.candidatesCount();
}).then(function(count){
asserts equal(count,2); //Chai Library Function
});
});
});
Election.sol file
contract Election {
//Model of Candidate
struct Candidate{
uint id;
string name;
uint voteCount;
}
//Store Candidate
//Fetch Candidate
mapping(uint => Candidate) public listOfCandidates;
//Store Candidate Count
uint public candidatesCount;
//construtor
constructor() public {
addCandidate("Candidate 1");
addCandidate("Candidate 2");
}
function addCandidate(string memory _name) private{
candidatesCount++;
listOfCandidates[candidatesCount] = Candidate(candidatesCount,_name,0);
}
}
