Testing task

Create a smart contract named Splitter whereby:

• there are 3 people: Alice, Bob and Carol.
• we should see the balance of the Splitter contract on the Web page.
• whenever Alice sends ether to the contract for it to be split, half of it goes to Bob and the other half to Carol.
• we can see the balances of Alice, Bob and Carol on the Web page.
• Alice can use the Web page to split her ether.

It would be even better if you could team up with different people impersonating Alice, Bob and Carol, all cooperating on a test net.

Prerequisites

• Users: (A)lice, (B)ob and (C)arol
• When A sends ETH to B and C, it splits 50/50
• A is able to split ETH on the website
• We are able to see total balance
• We are able to see separate balance of A, B and C.

Setting up your environment

• Check if Node.js and truffle are installed by typing in your terminal:
  • node -v
  • and then truffle version
• Install Ganache
• Initialize truffle truffle init to build a basic Truffle project
• Create package.json file by typing npm init
• Write contracts in the contracts folder.(Splitter.sol, Owned.sol, Toggled.sol)
• Modify truffle-config.js file (truffle.js for Mac).
• Run truffle compile to compile the contract
  • Please check the required version of the Solidity compiler (for all .sol files including imported libraries)
  • by running truffle version.
  • If needed, run npm uninstall -g truffle
  • and the npm install -g truffle
• Create 2_splitter_migration.js in the migrations folder.
• Run Ganache on your machine (select Quickstart)
• Run truffle migrate --reset to migrate the contract.

How to run tests splitter.test.js

• Run Ganache on your machine (select Quickstart)
• truffle test
