The Test Script The DappVotes test script has been meticulously designed to comprehensively assess and validate the functionalities and behaviors of the DappVotes smart contract. Below is a systematic breakdown of the primary tests and functions covered within the script: Test Setup: Before executing any tests, the script prepares essential contract instances and sets up addresses for testing purposes. It initializes parameters and variables that will be used throughout the test cases. The contract is deployed, and several signers (addresses) are assigned for simulated user interactions. Poll Management: This section encompasses the testing of poll creation, update, and deletion within the DappVotes smart contract. Under the category, a series of tests evaluate different scenarios to confirm the successful execution of these poll management functions. Success The test validates the creation of a poll by checking the list of polls before and after creation and confirming the attributes of the created poll. should confirm poll creation success The test demonstrates the successful update of a poll's attributes and validates the change. should confirm poll update success The test ensures the proper deletion of a poll by verifying the list of polls before and after deletion and confirming the deletion status of the poll. should confirm poll deletion success Poll Management Failure: This section encompasses negative test scenarios where poll creation, update, and deletion should fail. The tests under confirm that the contract correctly reverts with appropriate error messages when invalid or unauthorized actions are attempted. Failure Poll Contest: Within this section, the test cases focus on contesting in a poll, which involves entering as a contestant. Under , the test verifies that contestants can successfully enter a poll, and the number of contestants is accurately recorded. It also checks the retrieval of contestants' information. Success should confirm contest entry success The tests address scenarios where contest entry should fail, such as attempting to contest a non-existent poll or submitting incomplete data. Failure Poll Voting: This section evaluates the process of casting votes in a poll for specific contestants. Under , the test demonstrates successful voting by contestants and validates the accuracy of vote counts, voter addresses, and associated avatars. Success should confirm contest entry success The tests address scenarios where voting should fail, such as trying to vote in a non-existent poll or voting in a deleted poll. Failure Through this organized and detailed breakdown, the critical functionalities of the DappVotes test script are explained, illustrating the purpose and expected outcomes of each test scenario. The test script, when executed, will comprehensively validate the behavior of the DappVotes smart contract. At the root of the project, create a folder, if not existing, called “ ” and copy and paste the code below inside of it. test https://gist.github.com/Daltonic/c6a91aa385853802ee5160c0ab9aa304?embedable=true Run the following commands to have your local blockchain server running and also test the smart contract: yarn hardhat node yarn hardhat test By running these commands on two separate terminals, you will test out all the essential functions of this smart contract. The Deployment Script The DappVotes deployment script is designed to deploy the DappVotes smart contract to the Ethereum network using the Hardhat development environment. Here's an overview of the script: Import Statements: The script imports the required dependencies, including for Ethereum interaction and for file system operations. ethers fs main() Function: The function serves as the entry point for the deployment script and is defined as an asynchronous function. main() Deployment Parameters: The script specifies the parameter, which represents the name of the smart contract to be deployed. contract_name Contract Deployment: The script uses the method to obtain the contract factory for the specified . ethers.getContractFactory() contract_name It deploys the contract by invoking the method on the contract factory, which returns a contract instance. deploy() The deployed contract instance is stored in the variable. contract Contract Deployment Confirmation: The script waits for the deployment to be confirmed by awaiting the function on the contract instance. deployed() Writing Contract Address to File: The script generates a JSON object containing the deployed contract address. It writes this JSON object to a file named in the directory, creating the directory if it doesn't exist. contractAddress.json artifacts Any errors during the file writing process are caught and logged. Logging Deployed Contract Address: If the contract deployment and file writing processes are successful, the deployed contract address is logged to the console. Error Handling: Any errors that occur during the deployment process or file writing are caught and logged to the console. The process exit code is set to 1 to indicate that an error occurred. This DappVotes deployment script streamlines the process of deploying the smart contract and generates a JSON file containing the deployed contract address for further utilization within the project.
