Writing the unit test of the voting smart contract

To make sure the smart contract works well, you need to confirm it with unit tests. The way you write the unit test is similar to what you did in the previous chapter.

First, create the conftest.py file inside the tests folder, then add the following code to it:

import pytest
@pytest.fixture
def deployer(accounts):
    return accounts[0]
@pytest.fixture
def contract(deployer, project):
    return deployer.deploy(project.VotingApp)

This file contains the initial setup and configuration required for your test file to run properly. The deployer function returns the deployer, which uses the first test account. The contract function is used to deploy the voting smart contract.

Next, let’s create the test_voting_app.py file inside the tests folder and add the following code to it:

import pytest
from ape.exceptions import ContractLogicError
def test_chairperson(contract, deployer...
