# Foundry Smart Contract Lottery
## About
Players can enter the raffle by paying in ETH and a random winner will be picked by chainlink nodes.
## Workflow
- [Checkout the Complete Workflow](./test/unit/RaffleTest.tree)
## Test
```sh
forge test
```
| File | % Lines | % Statements | % Branches | % Funcs |
| ------------------------- | --------------- | --------------- | ------------ | --------------- |
| script/DeployRaffle.s.sol | 100.00% (17/17) | 100.00% (21/21) | 50.00% (2/4) | 100.00% (1/1) |
| src/Raffle.sol | 100.00% (36/36) | 100.00% (45/45) | 87.50% (7/8) | 100.00% (10/10) |
or
```sh
forge test --rpc-url
```
### Test Coverage
```sh
forge coverage
```
```sh
forge coverage --report debug > coverage.txt
```
- To generate lcov report
```sh
make generateTestReport
```
## Deploy
This will default to your local node. You need to have it running in another terminal in order for it to deploy.
```sh
make deployToAnvil
```
## Deployment to a testnet or mainnet
1. Setup environment variables
- You'll want to set your `SEPOLIA_RPC_URL` in environment variables. You can add them to a `.env` file, similar to what you see in `.env.example`.
2. Use wallet options to Encrypt Private Keys
- [Private Key Encryption](https://github.com/allwin199/foundry-fundamendals/blob/main/DeploymentDetails.md)
Optionally, add your `ETHERSCAN_API_KEY` if you want to verify your contract on [Etherscan](https://etherscan.io/).
### Get testnet ETH
Head over to [faucets.chain.link](https://faucets.chain.link/) and get some testnet ETH. You should see the ETH show up in your metamask.
### Deploy
```sh
make deployToSepolia
```
This will setup a ChainlinkVRF Subscription for you. If you already have one, update it in the `scripts/HelperConfig.s.sol` file. It will also automatically add your contract as a consumer.
### Register a Chainlink Automation Upkeep
- [Documentation](https://docs.chain.link/chainlink-automation/compatible-contracts)
- Go to [automation.chain.link](https://automation.chain.link/new) and register a new upkeep. Choose `Custom logic` as your trigger mechanism for automation.
## Estimate gas
You can estimate how much gas things cost by running:
```sh
forge snapshot
```
And you'll see an output file called `.gas-snapshot`
