IMPORTANT - We're incredibly excited by the enthusiasm the community is showing towards writing Ante Tests for their favorite protocols. We're still working on making the test deployment process as seamless and user-friendly as possible.

To help with this, we ask that you open a PR against this repo and get feedback from our community before deploying your ante test on-chain

Install Node and NPM (Instructions)

Make sure to use Node version 14 or higher and NPM version 6 or higher

Fork the ante-community-tests repository by clicking the Fork button in the upper right hand corner of this page, then clone your fork to your local machine with

git clone [email protected]:[YOUR_GITHUB_USERNAME]/ante-community-tests.git

Install all required packages

npm install --save-dev

• copy .env.example to .env and fill in your Infura API Key, Alchemy API Key, the mainnet private key for your desired mainnet deployment address, and memnonic phrase. The first address generated by this mnemonic is used to deploy contracts from this repo to testnet and mainnet
• If you do not have a mnemonic you can use test test test test test test test test test test test junk
• An Alchemy API key is required to run the testing suite and can be obtained for free at alchemy.com
• An Infura API key can be obtained for free at infura.io

Write an ante test for your desired protocol and put it in a file called ./contracts/[PROTOCOL_NAME]/[YOUR_TEST_NAME].sol. For more information on writing Ante Tests, see our docs. Also stop by our Discord and ask questions!

(Optional) you can also write some unit tests that check whether or not your AnteTest works. These unit tests should be placed in a file called ./test/[PROTOCOL_NAME]/[YOUR_TEST_NAME].spec.ts

Then run the following command:

npm run test

This command runs your unit tests against a forked version of the ethereum mainnet. Once you've verified everything is working properly, it's time to deploy your ante test to testnet and then mainnet!

If you are trying to run the testing suite with npx hardhat test, you must run npx hardhat typechain first to avoid an error where hardhat cannot find the typechain directory

Show off what you've built in our discord or tweet your PR at us on twitter! VERY IMPORTANT - Make sure to get feedback from our community before deploying your Ante Test to main-net! Testing and feedback are the best way to catch bugs early (and avoid wasting gas).

The following has been provided by @waynebruce0x and provides a beginner-friendly introduction to setting up a Hardhat development environment and writing an Ante Test from scratch:

There are many different tools and methods you can use to develop Ante Tests. In this guide we’ll use Hardhat and Alchemy, however feel free to adapt this guide to suit your favourite Ethereum development tools. Hardhat is an environment for developing, testing and deploying smart contracts, and Alchemy is an Ethereum node service which allows us to interact with projects already on the blockchain.

First we’ll need a recent version of Node.js, so we can run JavaScript code (which Hardhat is build on top of). Hardhat have an excellent guide on their website for installing Node.js. This is part of their Hardhat tutorial which we would recommend to anyone new to Ethereum development. https://hardhat.org/tutorial/setting-up-the-environment.html

Next we’re going to create a new project folder called AnteTest, and change your terminal directory to this folder so that any future commands run inside the AnteTest folder

mkdir AnteTest && cd AnteTest

Then create a new package.json file for your project, install hardhat, and run it. If these steps are successful you’ll see ‘welcome to Hardhat’ printed in your terminal. Use your arrow keys to select ‘Create an empty hardhat.config.js’

npm init -y
npm install --save-dev hardhat
npx hardhat

create an empty hardhat.config.js Great, so now we have your empty Hardhat project ready and waiting. Next we’ll install some plugins to make things easier. Openzeppelin have a bunch of libraries useful for Ethereum development. We’re just going to install hardhat-upgrades and contracts. Nomiclabs’ ethers library makes it easier for us to interact with the Ethereum blockchain.

npm install --save-dev @openzeppelin/hardhat-upgrades
npm install --save-dev @openzeppelin/contracts
npm install --save-dev @nomiclabs/hardhat-ethers ethers # peer dependencies

sign up to Alchemy at https://www.alchemy.com/. Once you have made a project / app you’ll be given a unique ‘integrate with alchemy’ URL. Keep this safe! This will allow us to fork the current state of the Ethereum blockchain, allowing us to interact with projects that have already been deployed (like AAVE, Uniswap, WBTC etc).

At this point it’s a good idea to open up the AnteTest project in your IDE. You should be able to see a hardhat.config.js file, open it up because we’re going to edit it’s contents. We’re going to add requirements for two of the plugins we just installed, and give your project details of your Alchemy node. Clear your hardhat.config.js file, then copy and paste the code below into it, where "[ALCHEMYURL]" is the http address of your Alchemy node. Make hardhat.config.js this:

require("@nomiclabs/hardhat-ethers");
require("@openzeppelin/hardhat-upgrades");
/**
* @type import('hardhat/config').HardhatUserConfig
*/
module.exports = {
  solidity: "[YOUR DESIRED VERSION]",
  networks: {
    hardhat: {
      forking: {
        url: "[ALCHEMYURL]",
      }
    }
  }
};

Make a new folder in the project called contracts, and inside that, make another folder called interfaces. Copy the IAnteTest interface and the AnteTest abstract class into this interfaces folder (you can find them here https://docs.ante.finance/antev05/tutorials/write-an-ante-test/iantetest.sol-and-antetest.sol)

For this step you need to get creative. There are some examples in the Ante docs that you can use as inspiration. Google search is great for getting ideas and debugging your contract, and if you get stuck you can always ask us questions in the Ante Discord server!

Put your test in the contracts folder when it’s finished. Then make a new folder called ‘scripts’, with a file ‘deploy.js’ inside it. You’ll also have to write the deployment script yourself (some help can be found here https://hardhat.org/tutorial/deploying-to-a-live-network.html).

Now you’re ready to check your Ante Test works as you expected! We’re going to run a fork of the current Ethereum mainnet. This means we can interact with the blockchain without losing any real money. This step is important because it lets us check that the Ante Test works without any issues (because even the best devs tests often don’t work first time!). Start up your local hardhat node

npx hardhat node

Then in a seperate terminal window, also in the AnteTest directory, compile your smart contracts, and deploy them to the Ethereum fork.

npx hardhat compile
npx hardhat run scripts/deploy.js --network localhost

Once finished, the smart contracts can be deployed to the Rinkeby network with a similar command.

npx hardhat run scripts/deploy.js --network rinkeby
