In a terminal window pointing at the project root directory, run the following commands:

truffle test ./test/SportsBook.test.js

How to run it

Start an instance of Ganache

Setup an instance of Ganache to run and listen through port 8545.

Start the web app server

In a terminal window pointing at the project root directory, run the following commands:

cd app; npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

Gamble!

The UI is configured to bet only a fixed amount of 30 finney, which is the minimum allowed bet.

To submit a bet, simply follow these steps:

1. Scroll down to the section with the title "Submit your bets!".
2. Chose your team by entring either 1 or 2 in the input field, (1: San Francisco, 2: Kansas City).
3. Change account in Metamask.
4. Bet for the opposite team with that new account.
5. Submit team scores and watch the counters reload and will reflect the scores you submitted.
6. .

Alternatively you can run the following commands on a Truffle console pointing to a Ganache instance listening on port 8545.

truffle console --network ganache

Also, theres already an instance of the contract that has already been deployed to the Ropsten testnet at the following address 0x69b9DC056FFb052a2fDF7C3112b484Bd27e75eaE.

truffle console --network ropsten

Within the Truffle console copy and paste all of the following commands.

let SB = await SportsBook.at('0x69b9DC056FFb052a2fDF7C3112b484Bd27e75eaE') // if using Ropsten
let A = await web3.eth.getAccounts()
SB.contract.methods.bet(1).send({from:A[0],value:30000000000000000})
SB.contract.methods.bet(1).send({from:A[1],value:60000000000000000})
SB.contract.methods.bet(1).send({from:A[2],value:90000000000000000})
SB.contract.methods.bet(1).send({from:A[3],value:90000000000000000})
SB.contract.methods.bet(2).send({from:A[4],value:30000000000000000})
SB.contract.methods.bet(2).send({from:A[5],value:30000000000000000})
SB.contract.methods.bet(2).send({from:A[6],value:60000000000000000})
SB.contract.methods.bet(2).send({from:A[7],value:60000000000000000})
SB.contract.methods.bet(2).send({from:A[8],value:90000000000000000})
SB.contract.methods.bet(2).send({from:A[9],value:90000000000000000})

After that, the admin account (A[0]) will report the game started will be reporting the scores of the game.

SB.contract.methods.reportGameEnded().send({from:A[0]})
SB.contract.methods.setScoreForSanFrancisco(20).send({from:A[0]})
SB.contract.methods.setScoreForKansasCity(31).send({from:A[0]})

Then, the admin will report the end of the game and the scores will effectively become immutable.

SB.contract.methods.reportGameEnded().send({from:A[0]})

Now, users can claim their payoffs!

SB.contract.methods.claimPayoff().send({from:A[0]})
