For testing, 2 types of tests are developed configured:

• Unit test
• Staging test

Mocks are also created for testing

Use different kinds of storage in different scenerios

Apply Solidity code convention

• git
• Node.js
• yarn

git clone [email protected]:nvtrinh2001/hardhat-fund-me.git
cd hardhat-fund-me
yarn
yarn hardhat

yarn hardhat deploy

Create your local hardhat network:

yarn hardhat node

And, in a different terminal:

yarn hardhat deploy --network localhost

Setup environment variables:

• PRIVATE_KEY
• RINKEBY_RPC_URL

Get testnet ETH from faucets.chain.link

Deploy:

yarn hardhat deploy --network rinkeby

yarn run test

yarn run test:staging

yarn run coverage

Run:
